| If - Else decision statement in Java Examples |
In Java, decision statements play a major role. Without using decision statements make your code may be lengthy or maybe you can't achieve your goal. This post contains some examples of java if-else decision statements. These examples help you to build your basics and you will get to know how you can write or use decision statements in Java Program. So let's begin!!
Examples
Example 1: Write a program in java to print whether the number is even or odd.
Code
public class evenodd {
public static void main(String args[]){
// Create a Scanner object
Scanner sc = new Scanner(System.in);
System.out.println("Enter the Number");
int Number = sc.nextInt();
if (Number%2==0){
System.out.println("The given number is Even");
}
else{
System.out.println("The number is Odd");
}
}
}
Output
Enter the Number
665
The number is Odd
Example 2: Write a program in Java to find that whether the input number is divisible by 2, 3, and 5.
Code
import java.util.Scanner;
public class JavaProgram {
public static void main(String args[]){
Scanner sc = new Scanner(System.in);
// Create a Scanner object
System.out.println("Enter the Number");
int Number = sc.nextInt();
if (Number%2==0 && Number%3==0 && Number%5==0){
System.out.println("This Number is correct");
}
else{
System.out.println("Try another Number");
}
}
}
Output
Enter the Number
30
This Number is correct
Enter the Number
6
Try another Number
Example 3: Write a program in java to print whether the number enter by the user is positive or not.
Code
import java.util.Scanner;
public class JavaProgram {
public static void main(String args[]){
Scanner sc = new Scanner(System.in);
// Create a Scanner object
System.out.println("Enter the Number");
int Number = sc.nextInt();
if (Number>0 & Number ==0){
System.out.println("This Number is positive");
}
else{
System.out.println("This Number is Negative");
}
}
}
Output
Enter the Number
-1
This Number is Negative
Example 4: Write a program in java to print whether the student is pass or fail on the basis of percentage.
Code
import java.util.Scanner;
public class JavaProgram {
public static void main(String args[]){
Scanner sc = new Scanner(System.in);
// Create a Scanner object
System.out.println("Enter the Percentage");
int Number = sc.nextInt();
if (Number>=40){
System.out.println("Student is Pass");
}
else{
System.out.println("Student is fail");
}
}
}
Output
Enter the Percentage
30
Student is fail
Enter the Percentage
54
Student is Pass
Example 5: Write a program in java to check whether the inputs given by the user are rectangle measurements or not.
Code
import java.util.Scanner;
public class Checkrectangle {
public static void main (String args[]){
Scanner sc = new Scanner(System.in);
// Create a Scanner object
System.out.println("Enter the Length Measurement");
int Length = sc.nextInt();
System.out.println("Enter the Breadth Measurement");
int Breadth = sc.nextInt();
if(Length>Breadth){
int c= Length*Breadth;
System.out.println("Area of Rectangle is: "+c);
}
else{
System.out.println("Please Enter the valid Dimensions
for the Rectangle as per the values assigned");
}
}
}
Output
Enter the Length Measurement
40
Enter the Breadth Measurement
30
Area of Rectangle is: 1200
Enter the Length Measurement
50
Enter the Breadth Measurement
60
Please Enter the valid Dimensions for the Rectangle as per the values assigned
