Java program to print numbers from 1 to N using for loop
This is an Example of java for loop - In this java program, we are going to print numbers from 1 to N using for loop.
Submitted by Chandra Shekhar, on March 09, 2018
To print numbers from 1 to N, we need to read the value of N by the user and then run a loop (we are using for loop here), logic to print numbers:
- First, we are creating an object named scanner of Scanner class to read the input.
- Declared a variable named n to store the value, given by the user, to read the input – we are using scanner.nextInt() – Here, nextInt() is the method of Scanner class, that will read an integer value.
- Then, using for loop from 1 to N to print the numbers from 1 to N.
Example:
Input:
Enter the value of N: 15
Numbers from 1 to 15

Program to print the number from 1 to N using for loop in java
import java.util.Scanner;
public class Print_1_To_N_UsingFor
{
public static void main(String[] args)
{
//create object of scanner class
Scanner scanner = new Scanner(System.in);
// enter the value of " n ".
System.out.print("Enter the value n : ");
// read the value.
int n = scanner.nextInt();
System.out.println("Numbers are : " );
for(int i=1; i<=n; i++)
{
System.out.println(i);
}
}
}
Output
Enter the value n : 15
Numbers are :
