I want to write the method PrintIsFun (int n), which prints the word Java n times. If n is negative, let the method print Error: negative n

My current code only works good for 1, if number is 2 it all becomes messy:

public static void main(String[] args){
    PrintIsFun(2);
}
public static void PrintIsFun(int n) {
    if (n < 0) {
        System.out.println("Error: negative n");
    } else {
        for (int i = 0; i < n; i  ) {
                System.out.print("   J    a   v     v  a ");
                System.out.print("   J   a a   v   v  a a ");
                System.out.print("J  J  aaaaa   V V  aaaaa ");
                System.out.print(" JJ  a     a   V  a     a ");
            }
        }
    }

Desired output if my n for example is 2

The solution. For loop for each row and few spaces in print statement and voila.

public static void PrintIsFun(int n) {
    if (n < 0) {
        System.out.println("Error: negative n");
    } 
    else {
        //first row
        for (int i = 0; i < n; i  ) {
            System.out.print("     J    a   v     v  a   ");
        }
        System.out.println();
        //second row
        for (int i = 0; i < n; i  ) {
            System.out.print("     J   a a   v   v  a a  ");
        }
        System.out.println();
        //three row
        for (int i = 0; i < n; i  ) {
            System.out.print("  J  J  aaaaa   V V  aaaaa ");
        }
        System.out.println();
        //fourth row
        for (int i = 0; i < n; i  ) {
            System.out.print("   JJ  a     a   V  a     a");
        }
        System.out.println();
    }
}

to print your desired output. I think you have to change your code like this below.

public static void PrintIsFun(int n) {
    if (n < 0) {
        System.out.println("Error: negative n");
    } else {
        for (int i = 0; i < n; i  ) {
            System.out.print("   J    a   v     v  a ");
        }
        System.out.println();
        for (int i = 0; i < n; i  ) {
            System.out.print("   J   a a   v   v  a a ");
        }
        System.out.println();
        for (int i = 0; i < n; i  ) {
            System.out.print("J  J  aaaaa   V V  aaaaa ");
        }
        System.out.println();
        for (int i = 0; i < n; i  ) {
            System.out.print(" JJ  a     a   V  a     a ");
        }
        System.out.println();
    }

it seems code isn't good which I wrote. Try to make your own code

If you want to print the ASCII-art on the same level you should use a for cycle on every print: by doing this way, at the second iteration of the cycle you will print on the 5th line, you can't come back to the 1st
