JVM Process During Complilation

Compiler :A software which converts high level language to machine level language. It complies the instructions at once and lists all the errors.
Interpreter : A software which converts High level language to machine level language line by line .It does not move to next line until the error is corrected.
Source Code : A set of instructions written in high level language which is taken as an input from the user .
Machine code : The source code which is Complied/Interpreted is known as Machine code .
Byte Code : Byte code is the simplest Form of Source code. Source code is compiled to an intermediate code called Byte code. It can easily pass from one computer to another.
Object Code :The conversion of high-level language to a machine code with help of a translator known as Object code.
Java Virtual Machine (JVM) :It is a virtual processor which processes byte code to machine code for various platforms. So ,Java Interpreter is known as JVM.
Compilation :The type of language conversion is termed as Compilation.
Interpretation : The process of conversion of the language is called Interpretation.

Write Java program to allow the user to input his/her age. Then the program will show if the person is eligible to vote. A person who is eligible to vote must be older than or equal to 18 years old.

import java.util.*;  class Vote { public static void main(String args[]) { int age; Scanner sc=new Scanner(System.in); System.out.print("What is your age?"); age=sc.nextInt(); if(age>=18) System.out.println("You are eligible to vote."); else System.out.println("You are not eligible to vote."); } } Output:What is your age? 18 You are eligible to vote.
