题目内容
请看下列代码public class Num {public static void main(String[] args) {go();}public static void go() {String o = "";for (int x = 0; x < 3; x++) {for (int y = 0; y < 2; y++) {if (x == 1)break;if (x == 2 && y == 1)break;o = o + x + y;}}System.out.println(o);}}

public class Num {public static void main(String[] args) {int x = 3;int y = 5;go(x, y);System.out.printf("x=%d,y=%d", x, y);}protected static void go(int num1, int num2) {if (num1 > num2) {num1 *= 2;} else {num2 += 5;}}}
下列代码的运行结果为：（）public class Num {public static void main(String[] args) {int[] arr={3,5};go(arr);for(int i:arr){System.out.print(i+" ");}}protected static void go(int[] num) {if (num[0] > num[1]) {num[0] *= 2;} else {num[1] += 5;}}}
下列代码的运行结果是（）public class NumOfEgg {public static void main(String[] args) {System.out.println("value =" + switchIt(4));}public static int switchIt(int x) {int j = 1;switch (x) {case 1:j++;case 2:j++;case 3:j++;case 4:j++;case 5:j++;default:j++;}return j + x;}}
