以下程序代码中有什么错？public class TestObjectArray {public static void main(String[] args) {Integer[] list1 = { 12, 24, 55, 1 };Double[] list2 = { 12.4, 24.0, 55.2, 1.0 };int[] list3 = { 1, 2, 3 };printArray(list1);printArray(list2);printArray(list3);}public static void printArray(Object[] list) {for (Object o : list)System.out.print(o + " ");System.out.println();}}
