How do you convert a number value into that amount of characters? [duplicate]

by

I want to convert a number (20) into vertical lines and have those lines display a character (*) increasing by one as the lines increase.

I have:

import java.util.*;

public class increase {

    public static void main(String[]args) {
        Scanner input = new Scanner (System.in);
        
        System.out.println("Please enter the rumber of rows.");
        int tot = input.nextInt();
        
        for(int rows=0; rows<=tot; rows++) {
            System.out.println((rows to characters here));
        }
    }
}

  • Can you, please, give an example of what you want? For an example, the input does not necessarily have to be 20.

    – 

  • 1

    something like "*".repeat(count) ? But not clear what is meant by “rows to characters“. These whole question seem like one of the many draw a triangle pattern assignments

  • Try the following, for (int i = 1; i <= 20; i++) System.out.println(“*”.repeat(i));.

  • The question might not be a duplicate of the question linked in the closed notice. But, this question is lacking in details, so could be closed for that reason.

You can achieve this by modifying your for loop to control the number of characters printed on each line:

import java.util.*;

public class Increase {
    public static void main(String[] args) {

        Scanner input = new Scanner(System.in);

        System.out.println("Please enter the number of rows.");
        int tot = input.nextInt();

        for (int rows = 1; rows <= tot; rows++) {
            // Print '*' characters based on the current row number
            for (int i = 1; i <= rows; i++) {
                System.out.print("*");
            }
            // Move to the next line after printing the characters
            System.out.println();
        }
    }
}
