2D array

Hello,

Could someone help me out, I am very new to programming( as one could tell by the Question I am about to ask.)

I am trying to assign a value to random spots in a 2D array. This is what I have so far:

Code:

[COLOR=Blue]
   /** 
     * Generates random coordinates, puts them into a new CoordinatePair,
     * returns CoordinatePair - This method is complete and requires no change.
     * @return a randomly-generated pair of coordinates within the bounds of the
     * grid
     */[/COLOR]
    private CoordinatePair getRandomCoordinates()
    {
        CoordinatePair coords = new CoordinatePair();  // create a new coordinate pair object
        coords.setRow(random.nextInt(ROWS));           // randomly select a row, put row info into object
        coords.setColumn(random.nextInt(COLUMNS));     // randomly select a column, put column info into object
        return coords;                                 // return the object
    }
    
   [COLOR=Blue] /**
     * Invokes getRandomCoordinates() to put a specific value into the number of
     * grid positions specified by the first parameter, e.g. 
     * setRandomCoordinates(5, 'T') will set the target char 'T' into 5 different
     * locations in the grid on which it is invoked. This method will be invoked on the 
     * working grid.
     * @param the number of randomly-generated coordinates to set with the value,
     * the target value to set
     */
 [/COLOR]   

This is where I need help, setting up this next method:

public void setRandomCoordinates(int numCoordsToSet, char valueToSet)
