Verification of Java Path.

In this article,what is  Java path? and Verification of Java path? is explained in detail with images of how to set the path.

The class path variable is one way to tell the applications, including the Java Development Kit (JDK) tools, where to look for user classes.(Classes that are part of the JRE,JDK platform, and extensions should be defined through other means, such as the class path or the extensions directory).

Step 1:Open the command prompt by typing cmd in the start menu or you can directly open by pressing (windows+r) and type CMD.

Step 2:CMD will be visible as below.  (From the topic what is  Java path? and Verification of Java path? )

Step 3:Type Javac command and press enter, it should show the paths in the Command prompt CMD.

Now the Java path is verified and we can start developing programs on Java. 

Note

Set the Verification of Java path environment variable, if you want to be able to conveniently run the executables (javac.exe, java.exe, javadoc.exe, and so on) from any directory without having to type the full path of the command. If you do not set the path variable, you need to specify the full path to the executable every time you run it, such as:

 C:\Java\jdk1.7.0\bin\javac example.java

The path environment variable is a series of directories separated by semicolons ";". Microsoft Windows looks for programs in the path directories in order(from left to right). You should have only one bin directory for the JDK in the path at a time (those following the first are ignored), so if one is already present, you can update that particular entry.

The following is an example of the path environment variable:
    C:\Java\jdk1.7.0\bin;C:\Windows\System32\;C:\Windows\;C:\Windows\System32\Wbem

It is useful to set the path environment variable permanently so it will persist after rebooting. To make a permanent change to the path variable, use the System icon in the Control Panel. The precise procedure varies depending on the version of the Windows.   (From the topic what is  Java path? and Verification of Java path? )
