3.  
4. public class ifExample { 
5.  
6. public static void main(String[] args) {
7.  
8. if(true){

Java program to compare two numbers in java

1. package com.instanceofjava; 
2. import java.lang.*; 
3.  
4. public class simpleIfExample { 
5.   
7. public static void main(String[] args) {
8.  
9.   int x= 37;
10.   int y= 37;
11.                
12. if(x==y){ 
13.     System.out.println(x+ " is equal to " + y);
14. }
15.  
16. if(x>y){
17.     System.out.println(x+ " is greater than " + y);
18. }
19.  
20. if(x<y){
21.     System.out.println(x+ " is less than " + y);
22. }
23. }

Output:

1. 37 is equal to 37

 Else Statement:

•  if(condition){ //} else { // }

5.   
7. public static void main(String[] args) {
8.  
9.   int x= 37;
10.   int y= 37;
11.                
12. if(x==y){
13.     System.out.println(x+ " is equal to " + y);
14. }else if(x>y){
15.     System.out.println(x+ " is greater than " + y);
16. }else{
17.     System.out.println(x+ " is less than " + y);
18. }
19. }

1. package com.instanceofjava; 
2. import java.lang.*; 
3.  
4. public class ifElseExample { 
5.   
7. public static void main(String[] args) {
8.  
9.     int year = 2015;                      
10.   //if year is divisible by 4, it is a leap year
11. 
    
12.  if((year % 400 == 0) || ((year % 4 == 0) && (year % 100 != 0)))
13.  System.out.println("Year " + year + " is a leap year");
14.  else
15.       System.out.println( year + " is not a leap year");
16.   
17.  
18. }

Output:

1. 2015 is not a leap year

6. public static void main(String[] args) {
7.   
8. int a=10;
9. if((a%2)==0){
10.  
11.  System.out.println(a+"is even number");
12.  
13. }else{ 
14. 
    
15.     System.out.println(a+"is odd number");
16.
