取最大最小题 求解,该如何解决

public class TestInput {    public static void main(String[] args) {    Scanner scanner = new Scanner(System.in);    int max = Integer.MIN_VALUE;    int min = Integer.MAX_VALUE;    System.out.print("请输入一个整数（输入0结束）");    while (scanner.hasNext()) {        try {                int temp = scanner.nextInt();        if (temp == 0)            break;            if (temp > max)            max = temp;        if (temp < min)            min = temp;        System.out.print("请输入一个整数（输入0结束）");        } catch (Exception e) {        try {            throw new Exception("输入错误");        } catch (Exception e1) {            e1.printStackTrace();        }        }    }    System.out.println("最大值为："+ max+" 最小值为：" + min);        }}
