We knew Form The articles before the JDK and the diffrence between it and the JRE , also we knew what is a complier and what we will use for writing a Java program
BUT How Does the machine understand the code that i write , We all Know That The machine understand only the machine code (0-OR-1) .. So We have to know How the Code that i write can be understood by the machine
JAVA PROGRAM LIFE CYCLE :
1 - You write Your code in a text editor (Ex. Notepad ) Or in an IDE (Ex. Netbeans) The File Saved From The compiler (IDE) Or the text editor is ".JAVA" (Ex. program.Java)
2- Then when you compile your code the file ".JAVA" is compiled to be ".Class" (Ex. program.Class)
3 - Now you have the ".Class" file Portable which can run On any Platform
4 - The ".Class" file is Interpreted By The JVM (Java Virtual Machine ) And The JVM turn the Code That You wrote to machine code ..
