*6.17(显示0和1构成的矩阵)编写一个方法,使用下面的方法头显示n * n的矩阵: public static void printMatrix(int n) 每个元素都是随机产生的0或1。编写一个测试程序,提示用户输入n,显示一个n * n矩阵。 以下是一个运行示例: Enter n:3 0 1 0 0 0 0 1 1 1 *6.17(Display matrix of 0s and 1s)Write a method that displays an n-by-n matrix using the following header: public static void printMatrix(int n) Each element is 0 or 1, which is generated randomly. Write a test program that prompts the user to enter n and displays an n-by-n matrix. Here is a sample run: Enter n:3 0 1 0 0 0 0 1 1 1
