java的二维数组

public class Matrix { public static void main(String[] args) { int[][] myarr = {{0,0,0,0},{0,0,0,0},{0,0,0,0}}; //int[][] myarr = new int[3][4]; for (int i = 0 ; i<myarr.length ;i++ ) { for (int j = 0;j<myarr[i].length ;j++ ) { System.out.print(myarr[i][j]+" "); } System.out.println(); } } }
