Java program

To start things of we will need a simple Java program. If you dont have it. Use this one. Save it as: DataTypes.java

First we need to find a compiler it will be usually found in C:\Program Files\Java\jdk1.8.0_152\bin
Find your file DataTypes.java . We have saved it this directory C:\Java
Next open CMD (Command prompt)
Type this line of code: cd C:\Program Files\Java\jdk1.8.0_152\bin
You will end up in C:\Program Files\Java\jdk1.8.0_152\bin>
Next we can type the command to compile. It will be this: javac C:\Java\DataTypes.java
Command line will execute, but nothing will be prompted. In the same location C:\Java you will find a compiled file DataTypes.class
If you want to run this program type: java -cp C:\Java\ DataTypes
That it is.
