621: Highlights

• If you want to catch an exception, then instantiate the following pattern:

  try { 
   ... 
   Statement with potential to throw exception 
   ... 
  } 
  catch (exception-class name parameter) { 
   exception-handling statements 
  } 
  

• If you want to catch input–output exceptions, then write a try–catch statement focused on the FileNotFoundException or IOException class.
• If you want to shut down a program, then write the following statement:

  System.exit(0); 
  

• If you want to add clean-up statements to a try statement, then add a finally block by instantiating the following pattern:

  finally { 
   clean-up statements 
  }
