Question

java readLine()为什么会错误呢?

import java.io.*;
import java.io.BufferedReader;
import java.io.InputStreamReader;

public class revenue {

public static void main(String[] args)
{
BufferedReader in=new BufferedReader(new InputStreamReader(System.in));
String inputLine=in.readLine();
}
}
错误信息:
revenue.java:10: unreported exception java.io.IOException; must be caught or declared to be thrown
String inputLine=in.readLine();

Answer 1

try{
String inputLine=in.readLine();
}
catch(IOException ex){}
