java

Question 1

We will go with some terminology

Answer 1

In Java when we write code, you will make a source code file which has .java extension, compile it using the javac compiler, and then run the compiled bytecode on a Java virtual machine.
After the Java code is compiled, the bytecode gets generated, which can be executed on any machine using JVM.
When you compile, java actually looks for syntax error so until you have the right syntax, the program will not run.
Bytecode is the .class file.

This is why Java is platform independent because you can run the bytecode in any Operating system.

Question 2

JVM

Question 3

Be able to write the main method

Answer 3

The main() method is where your program starts running.
Without main method JVM
It has public keywords so that everyone can acess it.
This keyword denotes it is a class. This is the name of the class. The opening curly brace and the end braces are required.
Every satement need to end in the semicolon.
