package Library;
import java.util.Scanner;
import java.util.Arrays;
public class shuming extends Exception {
public static void main(String[] args) {
String [] book=new String[]{"Thank in Java","Head First In Java","C pro"};
System.out.println(Arrays.toString(book));
try {
Scanner inqut=new Scanner(System.in);
int name = inqut.nextInt();
} catch (Exception e) {
String one=e.getMessage();
System.out.println(one);
}
}
}请问这里调用getMessage()方法输出的时候 我明明输入一段字符串 为什么输出结果是null 空??getmessage不应该输出异常信息吗?为什么我不能输出异常信息
