Java code to display all even or odd number from 1 to n
In this tutorial, we will discuss the Java code to display all even and odd number from 1 to n
In this program, we are going to learn about how to find odd or even number from 1 to given number using the loops in the Java language
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 side 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 ways to check whether the number is even or odd in Java language
Once This program received the number it will check the given number either odd or even number of given range using loops.
After receiving the input from the user, it is stored in the variable of num and then program divides the value of num by 2 and displays the output
Example for Java code to display all even or odd number from 1 to n
Print all even number using for loop
In this program, we display all even numbers from 1 to n using for loop
import java.util.Scanner;
class Even_Oddtill{
public static void main (String args[]){
int i;
Scanner scan=new Scanner(System.in);
//create a scanner object for input
System.out.print("Print all even number until:\n ");
int num=scan.nextInt();//Reads input from user and stored in variable num
System.out.print("Even number from 1 to "+num+" are: \n");
for(i=1; i<=num; i++){//loop for iterate from 1 to maximum
if(i%2==0){//using modular operator for finding even numbers
System.out.print(i+"\n");
}
}
}
}
When the above code is executed, it produces the following results
Print all even number until: 50 Even number from 1 to 50 are: 2 4 6 8 10 12 14 16 18 20 22 24 26 28 30 32 34 36 38 40 42 44 46 48 50
Program 2
Print all odd number using for loop
In this program, we print all odd numbers from 1 to n using for loop
import java.util.Scanner;
class Even_Oddtill1{
public static void main (String args[]){
int i;
Scanner scan=new Scanner(System.in);
//create a scanner object for input
System.out.print("Print all odd number until:\n");
int num=scan.nextInt();//Reads input from user and stored in variable num
System.out.print("Odd number from 1 to "+num+" are: \n");
for(i=1; i<=num; i++){//loop for iterate from 1 to maximum
if(i%2==1)
System.out.print(i+"\n");
}
}
}
}
When the above code is executed, it produces the following results
Print all odd number until: 50 Odd number from i to 50 are 1 3 5 7 9 11 13 15 17 19 21 23 25 27 29 31 33 35 37 39 41 43 45 47 49
Program 3
In this program, we print all even numbers from 1 to n using while loop
Print all even number using while loop
import java.util.Scanner;
class Even_Oddtill3{
public static void main (String args[]){
int i;
Scanner scan=new Scanner(System.in);
//create a scanner object for input
System.out.print("Print all even number until:\n");
int num=scan.nextInt();//Reads input from user and stored in variable num
System.out.print("even number from i to "+num+" are: \n");
i=1;
while(i<=num){//loop for iterate from 1 to maximum
if(i%2==0){
System.out.print(i+"\n");
}
i++;
}
}
}
When the above code is executed, it produces the following results
Print all even number until: 50 Even number from 1 to 50 are: 2 4 6 8 10 12 14 16 18 20 22 24 26 28 30 32 34 36 38 40 42 44 46 48 50
Print all odd number using while loop
In this program, we print all odd numbers from 1 to n using while loop
Program 4
import java.util.Scanner;
class Even_Oddtill2{

int num=scan.nextInt();//Reads input from user and stored in variable num
System.out.print("Odd number from i to "+num+" are: \n");
i=1;
while(i<=num){//loop for iterate from 1 to maximum
if(i%2==1){
System.out.print(i+"\n");
}
i++;
}
}
}

Program 5
In this program, we print all even numbers from 1 to n using the do-while loop
Print all even number using the do-while loop
import java.util.Scanner;
class Even_Oddtill4{
public static void main (String args[]){
int i;
Scanner scan=new Scanner(System.in);
//create a scanner object for input
System.out.print("Print all even number until:\n");
int num=scan.nextInt();//Reads input from user and stored in variable num
System.out.print("even number from i to "+num+" are: \n");
i=1;
do{ //loop for iterate from 1 to maximum
if(i%2==0){
System.out.print(i+"\n");
}
i++;
}
while(i<=num);
}
}
