Guys when i omit

Question

throws Exception
The code won't compile
Please tell me why

import java.io.*;

public class Solution{
public static void main(String[] args) throws Exception{

BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));

String s = reader.readLine();

System.out.println(s+" makes $12000 a year. Ha-ha-ha");

}
}

Answer 1

BufferedReader throws IOException, which is a checked exception. Checked exceptions are checked by the compiler at compile time and must be handled either by try catch or by throwing the exception up the callstack to a point at which it is handled. Since this is used in the main method and not handled via a try catch it is thrown up to the JVM where it is handled. Omitting either results in the error.
