问题及代码：
    
    
    Main.java

            Scanner cin = new Scanner(System.in);  
            row = cin.nextInt();  
            column = cin.nextInt();  
            System.out.println("Enter the array: ");

            }  
            Location a=new Location(row,column,array);
            Point x=new Point();
            x=a.getmaxPoint();
            System.out.println("The location of the largest element is "+(int)a.max +" at ("+(int)x.getx()+","+(int)x.gety()+")");  
        }  
    }
    
    
    Location.java

                    if(array[i][j]>max)
                    {
                    	max=array[i][j];
                    	maxPoint.setPoint(i,j);

    Point.java
