If else if Statement in Java

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

Let's start

Syntax: 

• It is used to test the condition.
• If executes only one condition at a time.
• The condition which is true first from the top will execute.
• if else if statement is used where we have to deal with only one condition at a time.

Example 1:

import java.util.Scanner;
class Easy
{
 public static void main(String[] args) 
 {
  Scanner in=new Scanner(System.in);
  int no=5;
  if(no>2)//condition true
  {
   System.out.println("Hello1");   
  }
  else if(no<2)//condition false
  {
   System.out.println("Hello2");   
  }
  else if(no==5)//condition true
  {
   System.out.println("Hello3");
  }
  else
  {
   System.out.println("Hello4");
  }
 }
}
/*
### Output ###
Hello1
because it executes only one condition 
which becomes true first from top.
*/

Here in the above example the value of number is 5 so condition first and third will be true but if else if statement execute only one condition which is true first from top so condition one will execute and the output will be Hello1

Note: If all the conditions will become false the else part will execute.

Example 2: Show result according to percent.

This is very interesting example of this topic here we are going to show result according to obtained percent.

Suppose that 

First division is in between  60 to 100

Second division is in between  45 to 59

Third division is in between  33 to 44

Fail                                         < 33

you can change this range as per your requirements, i am just telling how to code for this program.

To  make this program we will take a single variable of type float and after taking user input we will apply condition on it and print result according to percent.

import java.util.Scanner;
class Easy
{
 public static void main(String[] args) 
 {
  Scanner in=new Scanner(System.in);
  float p;//declaring variable for percent
  System.out.println("Enter your percent");
  p=in.nextFloat();
  if(p>=60)
   System.out.println("First div");    
  else if(p>=45)
   System.out.println("Second div"); 
  else if(p>=33)
   System.out.println("Third div");
  else
   System.out.println("Sorry!! you are fail!!"); 
 }
}
/*
### Output ###
Enter your percent
50
Second div
*/
