Ladder if-else statement
The ladder if-else statement is used to check the set of conditions in sequence. The ladder if-else statement is similar to if-else, but here we can check multiple conditions one after one until a condition is evaluated as true.
Syntax
if (<condition 1>) {
// Code to be executed if condition 1 is true
} else if (<condition 2>) {
// Code to be executed if condition 2 is true
} else if (<condition 3>) {
// Code to be executed if condition 3 is true
}
// N number of else if...
else {
// Code to be executed if all the conditions are false
}Example
In this program, we are going to find a grade for a student from the given percentage of all marks.
import java.util.Scanner;
public class LadderIfElseExample {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
System.out.println("Enter percentage : ");
int percentage = scanner.nextInt();
// ladder if else statement
if (percentage >= 90) {
System.out.println("A+ Grade");
} else if (percentage >= 80) {
System.out.println("A Grade");
} else if (percentage >= 70) {
System.out.println("B Grade");
} else if (percentage >= 60) {
System.out.println("C Grade");
} else if (percentage >= 50) {
System.out.println("D Grade");
} else {
System.out.println("Fail!");
}
}
