18-Sep-2024

Learn how to use if-else statements to make decisions in Java programs

In the if-else 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 the else block is executed.

Syntax :



if(condition) {

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

}
else {

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

}



Flow Chart:




 Example:



import java.util.Scanner;
public class if_elsetest {

    /**
     * @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");

}
else{

        System.out.println("not adult");

      }

    }

}
     


In this example, if age is grater than 18  then if block will exucuted ( output is adult ) other wise else block will exucuted ( output is not adult ).
