个人原创代码：编写Java Application程序的方法，声明一个矩阵类Matrix，成员变量是一个二维数组，设数组元素类型为int，请设计方法：

(1)构造方法：

Matrix() //构造一个10X10个元素的矩阵，没有数据

Matrix(int n,int m) //构造一个nXm个元素的矩阵，数据由随机数产生

Matrix(int table[][]) //以一个整型的二维数组构造一个矩阵

要求使用 this

(2) 实例方法：

public void output() //输出Matrix类中数组的元素值

public void transpose() //输出一个矩阵的转置矩阵

2.随机数求法：

Math.random( )返回0-1的小数,由上题中的Matrix类派生出正方形Square类，在构造方法中调用父类的构造方法（使用super）。-The original code of the individual: the preparation method of the Java Application program to declare a matrix class Matrix member variable is a two-dimensional array, set the array element type int, the design method:

(1) constructor:

Matrix ()// construct a 10X10 one element matrix, there is no data

Matrix (int n, int m)// construct a nXm elements of the matrix, the data generated by the random number

Matrix (int table [] [])// an integer of two-dimensional array construct a matrix

To the use of this

(2) an instance method:

public void output ()// output the array element values ​ ​ in the Matrix class

public void transpose ()// output a matrix transpose matrix

(2) random number and method:

Math.random () back to 0-1 decimal, square Square class derived from the Matrix class in the previous question, in the constructor to call the superclass constructor (using super).
