Java if, if...else Statement Examples

In this program, you'll learn to the usage of  if else by a given number. This is done by using a if else statement in Java.

Example 1 : If Student marks is grater than equal 60 print "passed" else "failed"

import java.util.Scanner;
public class Grade {
    public static void main(String args[]) {
        Scanner input = new Scanner(System.in);
        System.out.println("Enter your mark : ");
        int m = input.nextInt();
        System.out.print("Your result is ");
        if (m >= 60 && m <= 100) {
            System.out.println("Pass");
        } else if (m >= 0 && m <= 59) {
            System.out.println("Fail");
        } else {
            System.out.println("Your marks rang is wrong!");
        }
    }
}

When you run the program, the output will be:

Enter your mark : 
60
Your result is Pass

 

Enter your mark : 
120
Your result is Your marks rang is wrong!

 

Enter your mark : 
50
Your result is Fail

 

 

Example 2 : Write a program to work out how much a person pay to cinema ,Assume that the full price is Rs.200.00 ,The program should input the age and decide the following basis; under 5-free; age 5-12-full price; age 55 or over-free; *age limit between 0-100

import java.util.Scanner;

public class Ticket {
    public static void main(String args[]) {
        Scanner input = new Scanner(System.in);
        int p, a;
        p = 200;
        System.out.println("Enter your age : ");
        a = input.nextInt();
        System.out.print("Your ticket price is  ");
        if (a >= 55 && a <= 100) {
            System.out.println("free");
        } else if (a >= 13 && a <= 54) {
            System.out.println("Rs:" + p);
        } else if (a >= 5 && a <= 12) {
            System.out.println("Rs:" + p / 2);
        } else if (a >= 1 && a <= 11) {
            System.out.println("free");
        } else System.out.println("your age range is wrong!");
    }
}

When you run the program, the output will be:

Enter your age : 
100
Your ticket price is  free

 

Enter your age : 
25
Your ticket price is  Rs:200

Example 3 : Write a program to input three numbers and display them increasing numerical size

import java.util.Scanner;

public class Order {
    static public void main(String args[]) {
        Scanner input = new Scanner(System.in);
        int x, y, z;
        System.out.println("enter the value of x : ");
        x = input.nextInt();
        System.out.println("enter the value of y : ");
        y = input.nextInt();
        System.out.println("enter the value of z : ");
        z = input.nextInt();
        System.out.print("Decreasing order of three numbers : ");
        if (x > y && y > z) {
            System.out.println(x + "," + y + "," + z);
        }
        if (x > z && z > y) {
            System.out.println(x + "," + z + "," + y);
        }
        if (y > x && x > z) {
            System.out.println(y + "," + x + "," + z);
        }
        if (y > z && z > x) {
            System.out.println(y + "," + z + "," + x);
        }
        if (z > y && y > x) {
            System.out.println(z + "," + y + "," + x);
        }
        if (z > x && x > y) {
            System.out.println(z + "," + x + "," + y);
        }
    }
}

When you run the program, the output will be:

enter the value of x : 
5
enter the value of y : 
1
enter the value of z : 
56
Decreasing order of three numbers : 56,5,1
