If else statement in Java

Hello friends how are you, today in this blog i will teach you what is if else statement, syntax of if else , how if else statement works and many programs using if else in a very simple way. 

Let's start

Syntax: 

• If else is a part of conditional statement.
• It is used to test the condition.
• If the condition is true body of if will execute otherwise body of else execute.

Example 1:

Here in this example value of a is 10 and value of b is 20 , condition is a>b means it is false because 10 is not greater than 20 so because of false condition else part will execute and output will be b is greater .

class Easy
{
 public static void main(String[] args) 
 {
  int a=10,b=20;
  if(a>b)//a greater than b(false)
  {
   System.out.println("a is greater");
  }
  else
  {
   System.out.println("b is greater");   
  }   
 }
}
/*
### Output ###
b is greater
*/

Example 2: Check given number is even or odd.

Here in this example we are going to check given number is even or odd . A number which is divisible by 2 and generates a remainder of 0 is called even number.

So here we will take a single variable for number and after taking user input we will apply condition on it. After dividing the number by 2 if the remainder is 0 then we will print Even otherwise we will print Odd. 

import java.util.Scanner;
class Easy
{
 public static void main(String[] args) 
 {
  Scanner in=new Scanner(System.in);
  int no;
  System.out.println("Enter any number");
  no=in.nextInt();
  //number exactly devided by 2 is called even
  if(no%2==0)
   System.out.println("number is even");    
  else
   System.out.println("number is odd");        
 }
}
/*
### Output ###
Enter any number
5
number is odd
*/
