Transcript installing Java. - Whitley County Schools

The Basic Java Tools
A text editor to write Java program source code.
A compiler to translate source code into bytecode.
An interpreter to translate and execute bytecode.
3 Steps of a Java Program
1. Write the Java source in some text editor.
The source code file must end with .java
2. Translate the source code file with a Java
compiler into an intermediate bytecode file
that will end with .class
3. Execute the bytecode file with a Java Virtual
Machine (JVM) program, which is an interpreter.
Note: All three of these steps can be done with a
text editor and the command prompt or an Integrated
Development Environment (IDE), like JCreator.
