我在学习JAVA的讲义

class Ex070204{
	static int[][] transpose(int[][] x){
		int[][] y= new int[x[0].length][x.length];
		for (int i=0;i<x.length;i++){
			for (int j=0;j<x.length;j++){
				y[j][i]=x[i][j];
				}
			}
		return y;
	}
	public static void main(String[] args){
		int[][] x = new int[4][6];
		for (int i=0;i<x.length;i++)
			for (int j=0;j<x[0].length;j++)
				x[i][j]=(int)(Math.random()*101);

		int[][] y=transpose(x);
		System.out.println("初始矩阵是: ");
		for (int i=0;i<x.length;i++){
			for (int j=0;j<x.length;j++)
				System.out.print(""+x[i][j]+"\t");
			System.out.println();
		}
		System.out.println("\n转置矩阵是: ");
		for (int i=0;i<x.length;i++){
