You can master these tricks and become adept at using the Bash shell, which is used as default on majority of Linux distributions. So here are seven tricks that have been outlined below mainly for the less experienced users. </span><br /> <span style="color: black; font-family: verdana; font-size: small;"><br /></span> <span style="font-size: small;"><br /><span style="color: black; font-family: verdana;"><b>1. Tab Completion –</b> This helps in saving time and is quite useful if you are unsure about a file or a command’s precise name. For instance, if there is a file with a really lengthy name and you want to delete it, you will need to type the file name escaping the space characters properly i.e you need to (insert the \ character before each space).<br /><br />If you type rm r and press Tab, the Bash will instantly fill the file’s name for you. In case of many files beginning with the letter r, Bash will not be able to identify the one you need. <br /><br /><b>2. Pipes –</b> This allows you to send the output of a command to a different command. According the UNIX every program is a small utility, which specializes in doing one thing. For instance, the ls command is used to list the files in the current directory and the grep command is used for searching its input for a specific term.<br /><br />If you combine these with pipes then you can conduct search for a file in the current directory. <br />ls | grep word<br /><br /><b>3. Wild Cards -</b> The * character (the asterisk) is a wild card that can be used for matching anything. For instance, if you wish to delete both the long file name and we wanted to delete both the “really long file name” and “really very long file name” from the current directory, you can run the command:<br />rm really*name<br /><br /><b>4. Output Redirection -</b> The > character can be used to redirect a command’s output to a file in place of another command. For instance, the line below runs the ls command to list the files in the current directory. However, in place of printing that list to the terminal, it prints the list to a file named “file1” in the current directory:<br />ls > file1<br /><br /><b>5. Command History –</b> The Bash can recall a history of the commands typed into it. You can make use of the up and down arrow keys for scrolling through the commands that have been used by you recently. The history command prints out a list of these commands to pipe it to grep to search for commands used recently.<br />~, . & ..<br /><br />The ~ character called the tilde symbolizes the current user’s home directory. In place of typing cd /home/name for going to home directory, you can type cd ~ instead.<br /><br /><b>6. Run a Command in the Background –</b> As a standard Bash executes each command that is run by you in the current terminal. It’s okay but what about when you want to launch an application and continue using the terminal. By typing firefox for launching Firefox, this will take over your terminal and show error messages and other output till you close it. By adding the & operator to the end of the command for allowing Bash to execute the program in the background use:<br />firefox &<br /><br /><b>7. Conditional Execution –</b> Bash can be used for running two commands in sequence. The second command can only be executed once the first command is completed successfully. For doing this you need to put both commands on the same line and separate it by a &&, or double ampersand.<br /><br />For instance, the sleep command obtains a value in a matter of a few seconds, counts down, and completes successfully. It’s not useful by itself but can be used for running another command after a delay. The command given below will wait for five seconds and launch the gnome-screenshot tool:<br />sleep 5 && gnome-screenshot</span></span>

Hacking is a global issue and which send the Internet world into turbulence. Hacking news reminds us every now and then that all your devices are vulnerable to hacks and you can become a victim anytime. A detailed report about the scariest side of hacking was recently released by WebHostingBuzz which gives us a list 10 scariest hacks and also possibilities in the world.</span><br /> <br /> <span style="color: black; font-family: verdana; font-size: small;"><span style="color: black; font-family: verdana;"><b>1. Commercial Plane Hacks: </b><br /><br />It's possible that satellite communication equipment can be hacked on passenger jets through Wi-Fi systems. In this way avionics equipment can be easily hacked and satellite communications can also be disrupted, which will have a direct impact on navigation and safety systems.<br /><br /><b> 2. Smart TVs: </b><br /><br />If your smart TV allows you to do social networking, then the apps can also allow hackers spy on you, the set's owner directly. These televisions have minimum level of security measures which may leave you highly vulnerable in front of hackers.<br /><br /><b> 3. Medical Equipment: </b><br /><br />Medical equipment which get implanted on your body like an insulin pump or a pacemaker may land you in the middle of hacking threats due to the wireless functions going on inside the machines.<br /><br /><b> 4. Appliances: </b><br /><br />In 2012, German researchers used smart electric meters to access information about residents' personal daily data which proves smart devices or appliances at our house leave us vulnerable to hackers.<br /><br /><b> 5. Power Plants: </b><br /><br />In 2013 a research report released that vulnerabilities are also present in power plants across the U.S. and Canada. These vulnerabilities keep us open to hacking possibilities and if this hack happens then all the servers which control power plants, electronic substations and water utilities, will be hijacked all throughout.<br /><br /><b> 6. Vehicles: </b><br /><br />Modern cars which have electronic control units are quite vulnerable to hacks as any outsider can unlock the car after hacking these devices and then just sends a text and starts the vehicle, leaving you completely clueless thereafter.<br /><br /><b> 7. Drones: </b><br /><br />In 2011 An American drone was crashed by Iranian military as false GPS signals were delivered. Reports and claims by the U.S. military says that the crash-landing was caused by a routine malfunction but experts revealed that the drone was a victim of one of the scariest hacks in the world.<br /><br /><b> 8. Voicemails: </b><br /><br />In July 2011, a phone hacking scandal rocked the world as British tabloid News of the World was shut down following the incident. Then revelations came around that the news company used to hack phones of celebrities and others and also used to gain access to their voicemails. Voicemail hacks are obviously one of the scariest ones ever in this world.<br /><br /><b> 9. ATMs: </b><br /><br />Bank of Montreal ATMs were hacked by two Canadian school-going boys in June 2014 which alarmed banks to enhance their security measures. Weak passwords, configuration issues and other basic security flaws leave ATMs vulnerable to hacks.<br /><br /><b> 10. Photos: </b><br /><br />This is the latest biggest example of hacking when Hollywood celebrities' nude pictures were posted online in August. These photos were stolen from iCloud like back-up services. More than 100 names were present on the hacker's list and this incident also sparked an FBI inquiry.</span> </span>

So, the main function also has to be a part of a class. Moreover, in Java there is one main() function for every class. This can come in handy when writing unit tests for the class.<br /><br />class HelloWorld<br />{<br /> public static void main(String X[])<br /> {<br /> System.out.println( "Hello, World" );<br /> }<br />}<br /><br /><b>Compiling</b><br /><br /><i>C++</i><br /><br />In C++, you will be compiling as, <br /><br />g++ X.cc -o outfile<br /><br />This will then be run with,<br /><br /> ./outfile<br /> <br /><i>Java</i><br /><br />In Java, you will compile the classes in X.java. <br /><br />javac X.java <br /><br />You have to run this by invoking the static main method.<br /><br /><b>Class declarations</b><br /><br />While C++ requires a semicolon at the end of class declarations, Java does not have any such requirement.<br /><br /><i>C++</i><br /><br />class X{};<br /><br /><i>Java</i><br /><br />class X{}<br /><br /><b>Method declarations</b><br /><br />A method declaration in Java must be a part of a class always. Otherwise, both the languages are quite the same syntactically on this front. You can also use the public, private and protected access specifications in Java.<br /><br /><b>Constructors and destructors</b><br /><br />In the case of constructors, the syntax in both C++ and Java is the same. Java though has no exact replacement for destructors. <br /><br /><b>Static members</b><br /><br />Static members (variables and functions) are also declared in the same way in both the languages. But, Java allows for static initialisation blocks in order to initialise static variables.<br /><br />class Foo <br />{<br /> static private int x;<br /> // static initialization block<br /> { x = 5; }<br />}<br /><br /><b>Scoop static namespaces and methods</b><br /><br /><i>C++</i><br /><br />In C++, you will use the Class::method form in order to scoop static methods.<br /><br />class MyClass<br />{<br /> public:<br /> static do();<br />};<br /><br />Use this by,<br /><br />MyClass::do();<br /><br /><i>Java</i><br /><br />In Java, on the other hand, scooping comes with the use of the .again parameter. This is similar to accessing the fields of a class.<br /> <br />class MyClass<br />{<br /> public static do()<br /> {<br /> // do something<br /> }<br />}<br /><br />To use the static method.<br /><br />MyClass.doStuff();<br /><br />Object declarations<br />C++<br /><br /> // on the stack<br /> myClass x;<br /><br /> // or on the heap<br /> myClass *x = new myClass;<br /> <br /><b>Accessing fields from various objects</b><br /><br /><i>C++</i><br /><br />In order to access fields from classes and other such objects, the programmer has to use dots. <br /><br />myClass x;<br />x.field;<br /><br />If a pointed is involved, then the narrow operator (->) has to be used.<br /><br />myClass x = new MyClass();<br />x->field;<br /><br /><i>Java</i><br /><br />In Java, only the dot is used. Since we always use references in Java, even pointers are accessed using the dot.<br /><br />myClass x = new MyClass();<br />x.field;<br /><br /><b>Protection levels</b><br /><br />They are specified in a different manner.<br /><br /><i>C++</i><br /><br /> public:<br /> void X();<br /> void Y();<br /><br /><i>Java</i><br /><br /> public void X();<br /> public void Y();<br /> <br /><br /><b>Virtual functions</b><br /><br /><i>C++</i><br /><br />virtual int X(); <br /><br />Virtual functions can also be used non virtually. You can simply say into X().<br /><br /><i>Java</i><br /><br /> int foo(); // or, final int foo();<br /><br />In Java, functions are always virtual by default. You use ‘final’ in order to avoid them from being overridden. <br /><br /><b>Abstract Classes</b><br /><br /><i>C++</i><br /><br />All you need to do is include public virtual functions./<br /><br /> class X{ public: virtual void X() = 0; };<br /><br /><i>Java</i><br /><br />In Java the syntax allows the programmer to be explicit.<br /><br /> abstract class X{ public abstract void X(); }<br /><br />If you want to specify an interface, then say,<br /> interface X{ public void foo(); }<br /><br />In that case though, you will have to implement it by,<br /> class Y implements X<br /> {<br /> public void M() { /* do something */ }<br /> }<br /> <br /><b>Memory management</b><br /><br />This is also pretty much the same in both the languages, except that Java has garbage collection, so no delete for Java. </span>
