尝试对文件IO使用nextint()时出现不匹配异常错误

import java.util.Scanner;

public class FileIOExample {

        Scanner scanner = new Scanner(System.in);

        while (scanner.hasNext()) {

            } else {

                System.out.println("非整数类型数据：" + input);
            }
        }

        scanner.close();
    }
