Arrays

public class ArraysDemo {
    public static void main(String[] args) {
        int temp[] = {3, 5, 7, 9, 1, 2, 6, 8};
        Arrays.sort(temp);
        System.out.println("排序后的数组 ： ");
        System.out.println(Arrays.toString(temp));
        int point = Arrays.binarySearch(temp, 3);
        System.out.println(point);
        Arrays.fill(temp, 3);
        System.out.println("数组填充 ： ");
        System.out.println(Arrays.toString(temp));
    }
}

Output

排序后的数组 ： 
[1, 2, 3, 5, 6, 7, 8, 9]
2
数组填充 ： 
[3, 3, 3, 3, 3, 3, 3, 3]
