Compiling
- 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.
