java Arrays工具类部分方法

        //Arrays.toString()
        int[] a = new int[]{1,2,3,4,5,6};
        System.out.println(a);
        System.out.println(a.toString());
        System.out.println(Arrays.toString(a));

        //Arrays.sort()
        int[] b = new int[]{6,3,7,1,3,8,4,3,0,3,2};
        System.out.println(Arrays.toString(b));
        Arrays.sort(b);
        System.out.println(Arrays.toString(b));

        //Arrays.binarySearch()
        int[] c = {18,62,68,82,65,9};
        Arrays.sort(c);
        System.out.println(Arrays.binarySearch(c,65));

        //Arrays.equals()
        int[] d = {18,62,68,82,65,9};
        int[] e = {18,62,68,82,65,9};
        int[] f = {18,62,68,82,65,8};
        System.out.println(Arrays.equals(d,e));
        System.out.println(Arrays.equals(d,f));
        System.out.println(Arrays.equals(e,f));

        //Arrays.fill()
        int[] g = new int[10];
        Arrays.fill(g,5);
        System.out.println(Arrays.toString(g));

输出结果如下

[I@1b6d3586
[1, 2, 3, 4, 5, 6]
[6, 3, 7, 1, 3, 8, 4, 3, 0, 3, 2]
[0, 1, 2, 3, 3, 3, 3, 4, 6, 7, 8]

true
false
false
[5, 5, 5, 5, 5, 5, 5, 5, 5, 5]
