The document describes a Java program that takes a user input for the number n and prints out the numbers from 1 to n on separate lines. It uses a Scanner to get the input number, a while loop to iterate up to n, and an inner for loop to print out the numbers from 1 to n on each line.

1. Write a program that takes an input of n and prints the numbers from 1 to n ( for n lines):
Solution
MainProgram.java
import java.util.Scanner;
public class MainProgram {
public static void main(String[] args){
int s=1;
Scanner in=new Scanner(System.in);
System.out.println("Enter your number elements: ");
int n=in.nextInt();
while(s<=n)
{for(int i=1; i<=n; i++){
System.out.print(i);
}
System.out.println();
s++;
}
}}
Output :
Enter your number elements:
6

123456
123456
