How do you print a character a random number of times?

[Ashley Kin]

Hi, I'm trying to write a method that will print a string of a random number of X's (from 5 to 20) on a line, then another number of X's on the next line, etc. until the random number = 16.
I have to use while loops and probably fencepost algorithms. I'm confused with how to print the number of x's the random number of times over and over.
Right now, I'm pretty sure my for loop is wrong or unnecessary.
Any help is greatly appreciated, thanks!

So far, this is my code:

public static void randomX() 
	{
		int x = 0;
		while (x != 16)
		{
			x = (int)(Math.random()*20) + 5;
			for (int i = 0; i <= x; i++);
			{
				System.out.print("x");
			}
		}
	}

And what happens when you run that code? I can only see one error.

[Campbell Ritchie]

Make that two errors.

three. I ought to learn to read.

Four. Most of them standard beginners’ errors. Look at the end of the line beginning for

Well, it's only printing one line of x's. I need it to continue to print lines of random numbers of x's until the random number is 16.
I'm thinking I went wrong with the for loop?

Earlier, I wrote:. . . Look at the end of the line beginning for

If I drop any heavier hints, they will go through the floor.

Yes, there's a small problem with big consequences at the end of line 7.

Have you really not read that line, AK? Look very carefully. You have even had hints which part of the line to look at first.

By the way: Insert this line before the line saying print("x")

//      Line only there for testing, so you can delete it later.
        System.out.printf("x = %2d: ", x); //test

If you are lucky, that will bring the other three errors to your notice. If you are unlucky, only two of them. One of those three errors is related to an error I pointed out yesterday in a different thread of yours about a different program.

public static void randomX()   
    {  
		throw new IfCampbellSeesThisCodeHeWillDeleteItException();
    
		
	}

[Campbell Ritchie]

No, no, no, no, no. You, Harsha Smith, are going to deprive AK of any chance of learning if you simply post code like that
