Question

Write code in JAVA

Write a program that will output a right triangle based on user specified input height (int) and specified input symbol (char).The first line will have one user-specified character, such as % or *. Each subsequent line will have one additional user-specified character until the number in the triangle's base reaches specified input height. Output a space after each user-specified character, including after the line's last user-specified character. Hint: Use a nested for loop.

Ex:If the input is:

Enter a character:

*

Enter triangle height:

8

the output is:

*

* *

* * *

* * * *

* * * * *

* * * * * *

* * * * * * *

* * * * * * * *

//TrianglePattern.java
import java.util.Scanner;
public class TrianglePattern {
    public static void main(String[] args) {
        Scanner scan = new Scanner(System.in);

        char ch;
        int n;

        System.out.println("Enter a character:");
        ch = scan.next().charAt(0);

        System.out.println("Enter triangle height:");
        n = scan.nextInt();

        System.out.println("the output is:");
        for(int i = 0;i<n;i++){
            for(int j = 0;j<=i;j++){
                System.out.print(ch+" ");
            }
            System.out.println();
        }
    }
