利用增强for循环进行遍历
public class Demo05 { //二维数组 public static void main(String[] args) { int[][] arrays = {{1,1,1,1},{45,8,9,7},{},{4,5,4,5},{4,9,8}}; printArrays(arrays); } public static void printArrays(int[][] arrays){ for (int[] array : arrays) { for (int i : array) { System.out.print(i + " "); } System.out.println(); } } }
