从键盘上输入输入5个整数到数组,求出数组中的所有偶数，用java语言？

参考技术A public static void main(String[] args)
int a[] = new int[5];
Scanner sc = new Scanner(System.in);
String o = "";
for (int i = 0; i < a.length; i++)
System.out.print("请输入第"+(i+1)+"位整数:");
a[i] = sc.nextInt();//只能录入整数
if (a[i]%2==0)
o+=","+a[i];


System.out.println("偶数为："+o.substring(1));
System.out.println("录入数组为："+Arrays.toString(a));
