Hi,
I have the following code,it prints out a 5 by 5 matrix and puts "-" in each location.
I need to ask user for the number of * they like to put in the matrix and based on the number they enter replace a random "-" by a "*".
It would be great if you modify my code and help me:
Here is an example:
How many * you want in the matrix?
3
-*---
*----
----*

import java.io.*;
import java.util.*;

class TestRandomArray1 {
private String [][] mBoard; // Good for a two-dimensional world
private int mDimension; // the size of the board
public TestRandomArray1(int dimension) {

mDimension = dimension;
mBoard = new String[mDimension][mDimension];
for (int i = 0; i < mBoard.length; i++)
for (int j = 0; j < mBoard[i].length; j++)
mBoard[i][j] = "-";
}

public void display() {

for (int i = 0; i < mBoard.length; i++) {
for (int j = 0; j < mBoard[i].length; j++)

System.out.print(mBoard[i][j]);

System.out.println();
}

}
public static void main(String[] argv) {

TestRandomArray1 runATest = new TestRandomArray1(5);
runATest.display();
}
}
