Java Programs

Java is another powerful and secure programming language, in this page we're trying to cover some simple, important, loop and array programs that will help you building flow how Java works. In order to play java programs on your computer, following are some steps to install Java.

Steps To install Java On Your Computer

First of all download JDK(Java Development Kit) on your computer

After installation click on start menu after that click on run and type cmd and press enter, Now open the folder where your Java programs are saved. For example suppose my programs are saved in java folder in c, Now type on command prompt

Now change directory using command cd java and press enter, Now you are in the java folder on c drive, after that you have to give the path where your JDK is installed after this you are ready to make and execute your program in java
