如下程序的输出结果是（ ）。public class Main { public static void main(String[] args) { int[] x = {1, 2, 3, 4, 5}; increase(x); int[] y = {1, 2, 3, 4, 5}; increase(y[0]); System.out.println(x[0] + " " + y[0]); } public static void increase(int[] x) { for(int i = 0; i < x.length; i++) x[i]++; } public static void increase(int y) { y++; }}
