Java If Statement

In the if control statement. Code will be executed based on a condition. If the condition is true then the if block is executed and if the condition is false then nothing will happen.

Syntax :

if(condition) {

  // if the condition is true then this block of code will execute

}

Flow Chart:

 Example:

import java.util.Scanner;
public class ifest {

    /**
     * @param args
     */
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        int age = sc.nextInt();

        if(age>18){

            System.out.println("adult");

        }

    }

}
      

In this example, if age is grater than 18  then if block will exucuted ( output is adult ). If the condition is false then nothing will happen.
