java的Arrays.fill()方法对二维数组赋值

解决方案

import java.util.Arrays;
public class Test {	 
	public static void main(String[] args) {
		// TODO Auto-generated method stub
		boolean[][] vis = new boolean[10][10];
		for (int m= 0; m < 10; m++) {//对m行进行赋值
			Arrays.fill(vis[m], false);
		}
	}
}

Arrays.fill(vis, false);

    public static void fill(Object[] a, Object val) {
        for (int i = 0, len = a.length; i < len; i++)
            a[i] = val;
    }

所以它里面只能对一维数组赋值

import java.util.Arrays;
public class Test {	 
	public static void main(String[] args) {
		// TODO Auto-generated method stub
		boolean[] vis = new boolean[10];//定义一个Boolean数组
		Arrays.fill(vis, false);
		Arrays.fill(vis,Boolean.FALSE);//或者
	}
}
