    Default ArrayIndexOutOfBoundsException

    So far, my loop will print the first element and then it errors out. Any suggestions would be great.

    public class Test {
     
    	/**
    	 * @param args
    	 */
    	public static void main(String[] args)
            {
    		Person a = new Staff(27, "Smith", "Gary", "Professor");
    		Person b = new Staff(12, "Doe", "Jane"," Professor");	
    		Person c = new Staff(6, "Anderson", "John", "Professor");
    		Person d = new Student(145, "Bee", "Corey", "Senior", "AMCS", "CS-250");
     
    		Person array[][] = {{a}, {b}, {c}, {d}};
     
    		for(int i=0; i<array.length; i++)
    		{
    			for(int j=0; i<array[i].length; j++)
    			{
    				System.out.print(array[i][j]);	//java.lang.ArrayIndexOutOfBoundsException: 1
    			}
    			System.out.println();
    		}
     
    	}
     
    }

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

    should be:

    for(int j=0; [b]j[/b]<array[i].length; j++)

    You accidentally put an i instead of a j in your condition. Fairly simple and understandable mistake.
