In this article, we will discuss the concept of Java program to display all odd or even numbers 1 to n with label using loops
In this post, we will learn how to find and display odd and even numbers with label using the loop.
Here, we will use for loop, while loop, and do-while loop to find and display odd and even numbers from 1 to n in Java programming language.
Program 1
This program allows the user to enter the maximum numbers. It finds and displays even and odd numbers with the label from 1 to entered number using for loop
import java.util.Scanner;
class OddEvenWithLabel{
public static void main(String args[]){
Scanner scan=new Scanner(System.in); //create a scanner object for input
System.out.print("Enter the random number: ");
int num=scan.nextInt();//get input from the user for num1
System.out.print("Display all odd and even number till "+num);
System.out.print("\n\n");
for(int i=1; i<=num; i++){
if(i%2==0){
System.out.print(i+" Is Even");
System.out.print("\t");
}
else{
System.out.print(i+" Is Odd\t");
}
}
}
} When the above code is executed, it produces the following results
Program 2
This program allows the user to enter the maximum numbers. It finds and displays even and odd numbers with the label from 1 to entered number using while loop.
import java.util.Scanner;
class OddEvenWithLabel1{
public static void main(String args[]){
Scanner scan=new Scanner(System.in); //create a scanner object for input
System.out.print("Enter the random number: ");
int num=scan.nextInt();//get input from the user for num1
System.out.print("Display all odd and even number till "+num);
System.out.print("\n\n");
int i=1;
while( i<=num){
if(i%2==0){
System.out.print(i+" Is Even");
System.out.print("\t");
}
else{
System.out.print(i+" Is Odd\t");
}
i++;
}
}
} When the above code is executed, it produces the following results
Program 3
This program allows the user to enter the maximum numbers. It finds and displays even and odd numbers with label 1 to entered number using the do-while loop.
import java.util.Scanner;
class OddEvenWithLabel2{
public static void main(String args[]){
Scanner scan=new Scanner(System.in); //create a scanner object for input
System.out.print("Enter the random number: ");
int num=scan.nextInt();//get input from the user for num1
System.out.print("Display all odd and even number till "+num);
System.out.print("\n\n");
int i=1;
do{
if(i%2==0){
System.out.print(i+" Is Even");
System.out.print("\t");
}
else{
System.out.print(i+" Is Odd\t");
}i++;
}while( i<=num);
}
} When the above code is executed, it produces the following results
