问题及代码：
Main.java
package first;  
import java.util.Scanner;  
public class Main {  
    public static void main(String[] args) {  
        int row, column ;  
        System.out  
                .print("Enter the number of tows anf columns of the array: ");  
        Scanner cin = new Scanner(System.in);  
        row = cin.nextInt();  
        column = cin.nextInt();  
        System.out.println("Enter the array: ");  
        double [][]array = new double[row][column];
        for(int i=0;i<row;++i)  
        {  
            for(int j=0;j<column;++j)  
            {  
                array[i][j]=cin.nextDouble();  
            }  
        }  
        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
package first;  
public class  Location {  
    public int row, column;
    double [][]array;
    double max;
    Point maxPoint=new Point();  
    Location (int a,int b,double a1[][])
    {
        row=a;
        column=b;
        array=a1;
    }
    Point getmaxPoint()
    {
        max=array[0][0];
        for(int i=0;i<row;++i)  
        {  
            for(int j=0;j<column;++j)  
            {  
                if(array[i][j]>max)
                {
                    max=array[i][j];
                    maxPoint.setPoint(i,j);
                }
            }  
        }
        return maxPoint;
    }   
}
Point.java
package first;
public class Point {
    double a,b;
    Point()
    {
        a=0;
        b=0;
    }
    Point(double x,double y)
    {
        a=x;
        b=y;
    }
    void setPoint(double x,double y)
    {
        a=x;
        b=y;
    }
    double getx()
    {
        return a;
    }
    double gety()
    {
        return b;
    }
}
运行结果：
