Display even and odd numbers without if statement in Java

Display even and odd numbers without if statement in Java

In this tutorial, we will discuss the concept of Display even and odd numbers without if statement in Java language.

In this post, we are going to learn how to display even and odd numbers without if statement in Java language.

 

First, we must understand how to identify an odd and even numbers

What is Even or Odd

When the number is divided by 2 and the balance becomes zero and the above number is called as the even number – eg 2,4,6,8,10

and on the other sides when it is divided by 2 and balance becomes 1 they are called odd numbers or uneven numbers

 

In my previous post, I have explained the various approaches to print odd and even numbers using if statements in Java programming language

 

here, we will discuss how to display odd and even numbers without if statements

 

There are three programs given below

Print even and odd numbers using for loop

Program 1

The program allows the user to enter the maximum number for display odd and even numbers using for loop in Java language

Then, it will display the even and odd numbers without if statements in Java language

import java.util.Scanner;
class EvenOddDisplay{
public static void main (String args[]){
Scanner scan=new Scanner(System.in);
//create a scanner object for input

System.out.print("Enter the maximum number\n");

int num=scan.nextInt();

//print even number using for loop without if statements
System.out.print("Even numbers are:");
for(int i=0; i<=num; i+=2){
System.out.print(i+" ");

}

//print odd number using for loop without if statements
System.out.print("\n\nOdd numbers are:");
for(int i=1; i<=num; i+=2){
System.out.print(i+" ");

}
}
}

 

When the above code is executed, it produces the following results

Enter the maximum number
25
Even numbers are: 0  2  4  6  8  10  12  14  16  18  20  22  24

Odd numbers are: 1  3  5  7  9  11  13  15  17  19  21  23  25

 

Print even and odd numbers using while loop

Program 2

The program allows the user to enter the maximum number for display odd and even numbers using while loop in Java language

Then, it will display the even and odd numbers without if statements in Java language

import java.util.Scanner;
class EvenOddDisplay1{
public static void main (String args[]){
Scanner scan=new Scanner(System.in);
//create a scanner object for input

System.out.print("Enter the maximum number\n");

int num=scan.nextInt();

//print even number using for loop without if statements
System.out.print("Even numbers are:");
int i=0; 
while(i<=num){
System.out.print(i+" ");
 i+=2;
}

//print odd number using for loop without if statements
System.out.print("\n\nOdd numbers are:");
i=1; 
while(i<=num){
System.out.print(i+" ");
 i+=2;
}
}
}

When the above code is executed, it produces the following results

Enter the maximum number
30
Even numbers are: 0  2  4  6  8  10  12  14  16  18  20  22  24 26  28  30

Odd numbers are: 1  3  5  7  9  11  13  15  17  19  21  23  25  2  29

 

Print even and odd numbers using the do-while loop

Program 3

The program allows the user to enter the maximum number for print odd and even numbers using do while loop in Java language

Then, it will display the even and odd numbers without if statements in Java language

import java.util.Scanner;
class EvenOddDisplay2{
public static void main (String args[]){
Scanner scan=new Scanner(System.in);
//create a scanner object for input

System.out.print("Enter the maximum number\n");

int num=scan.nextInt();

//print even number using for loop without if statements
System.out.print("Even numbers are:");
int i=0; 
do{
System.out.print(i+" ");
 i+=2;
}while(i<=num);

//print odd number using for loop without if statements
System.out.print("\n\nOdd numbers are:");
i=1; 
do{
System.out.print(i+" ");
 i+=2;
}while(i<=num);
}
}

 

When the above code is executed, it produces the following results

Enter the maximum number
30
Even numbers are: 0  2  4  6  8  10  12  14  16  18  20  22  24 26  28  30

Odd numbers are: 1  3  5  7  9  11  13  15  17  19  21  23  25  2  29
