有关2为数列的问题，求帮助
要求用一个类确定二位数列中最大值和最大值的位置。这个类包含public data field row,column,and maxValue去储存最大值和它的index，这个数列的row和column是整数类型，maxValue是double类型。使用public static Location locationLargest(double [][] a)作为类函数获得二维函数中最大值的位置。获得的值是一个instance of location. 用一个test 程序让用户输入一个二位数列，别且显示数列中最大值的位置。
以下是sample：
Enter the number of rows and columns of the array: 3 4
enter the array
35 2 10 4.3
23.5 4.5 3 45
33 44 5.5 9.6
The location of the largest element is 45 at (2,4)
哪位大神能帮忙做一下么，谢谢了。
