二维数组（Java入坑）11

创建Java文件Demo.java

public class Demo {
	public static void main(String[] args) {
		
		// 创建二维数组
		int[][] arr = new int[4][4];
		
		// 给第一个数组的第二个数赋值
		arr[0][1] = 2;
		
		int[][] brr = new int[][] {{2,4,5,6},{7,8,9},{10,1,0}};
		
		int[][] crr = {{2,4,5,6,},{7,8,9},{10,1,0}};
		
		// 循环遍历二维数组
		for (int i = 0; i < brr.length; i++) {
			for (int j = 0; j < brr[i].length; j++) {
				System.out.print(brr[i][j]+" ");
			}
			System.out.println("");
		}
