Unreported exception java.lang.exception

Question

Unreported exception java.lang.exception : Must be caught or declared to be throw. Why this problem will occur? Is it some simple method that can help to solve this problems

Answer 1

1. There are 2 ways to handle the exception.

 - Either `declare` it
 - or `Handle` it.

2. encrypt() method above throws an Exception

So either declare it on the method declaration in which you are calling it.

eg:

public void MyCallingMethod() throws Exception{

     byte[] pass = encrypt(password);
     String pw = new String(pass);


}

Or handle it with try/catch block, finally is optional

try{

     byte[] pass = encrypt(password);
     String pw = new String(pass);
   }catch(Exception ex){


  }
