The Java Else If Statement is an extension to Java If Else Statement and it is very useful when we have to check several conditions. We can also use the Nested If statement to achieve the same but as the number of conditions increase, code complexity will also increase. Let us see the syntax of the Else if in Java programming:
Java Else If Statement Syntax
The syntax of the Else If in Java Programming language is as follows:
|
1 2 3 4 5 6 7 8 9 10 11 |
if (condition 1) statement 1 else if (condition 2) statement 2 else if (condition 3) statement 3 ........... else if (condition N) statement N else default statements |
x = 18, y = 14
Condition 1: if (x != y) //TRUE
Condition 2: else if (x > y) //TRUE
In these situations, statements under the Condition 1 will be executed because ELSE IF conditions will only be executed if its previous IF or ELSE IF statement fails.
Flow Chart of a Java Else If Statement
Following picture will show you the flow chart behind this Else If in Java
Java Else If Statement example
This Java program allows the user to enter his / her grand total (total 6 subject marks). Using Else if in Java, we are going to calculate whether he / she is eligible for scholarship or not

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 |
// Example for Java Else If Statement package ConditionalStatements; import java.util.Scanner; public class ElseIfStatement { private static Scanner sc; public static void main(String[] args) { int totalmarks; sc = new Scanner(System.in); //Imagine you have 6 subjects and Grand total is 600 System.out.println(" Please Enter your Total Marks: "); totalmarks = sc.nextInt(); if (totalmarks >= 540) { System.out.println("Congratulations"); System.out.println("You are eligible for Full Scholarship"); } else if (totalmarks >= 480) { System.out.println("Congratulations"); System.out.println("You are eligible for 50 Percent Scholarship"); } else if (totalmarks >= 400) { System.out.println("Congratulations"); System.out.println("You are eligible for 10 Percent Scholarship"); } else { System.out.println("You are Not eligible for Scholarship"); System.out.println("We are really Sorry for You"); } } } |
OUTPUT 1: From the below screenshot you can observe that, We entered the totalmarks = 580. Here first If condition is TRUE so, statements inside the first If block will be executed.
OUTPUT 2: We are going to enter totalmarks = 510 means first IF condition is FALSE. It will check the else if (totalmarks >= 480), which is TRUE so it will print the statements inside this block. Although else if (Totalmarks >= 400) condition is TRUE, but it won’t check this condition.
OUTPUT 3: We are going to enter totalmarks = 450 means first IF condition, else if (totalmarks >= 480) are FALSE. So, It will check the else if (totalmarks >= 401), which is TRUE so it will print the statements inside this block.
OUTPUT 4: We are going to enter totalmarks = 380 means all the IF conditions Fail. So, It will print the statements inside the else block.
