At the command prompt type java space hyphen version and press Enter.
We see that the version number of the jdk has been displayed.
Depending on the version that you used your version number could be different.
So, we have successfully installed the jdk.
|
| Open the code in TextEditor.
|
Now, let us run a simple Java program and see if it works.
I already have the following code saved in the file name TestProgram dot java.
Let me compile and run this code.
This code simply displays We have successfully run a Java Program on the Terminal.
So let us go back to the Terminal.
Remember that I have saved the file TestProgram dot java in the Home directory.
