Java FAQ: Top Questions

Exception handling in Java manages runtime errors, ensuring program reliability using try , catch , finally , throw , and throws .

• try-catch: Code that might throw an exception is placed in a try block; exceptions are caught in catch blocks.
• finally: Executes code (e.g., resource cleanup) regardless of whether an exception occurs.
• throw: Explicitly throws an exception.
• throws: Declares exceptions a method might throw.
• Checked vs. Unchecked: Checked exceptions (e.g., IOException ) must be handled or declared; unchecked (e.g., NullPointerException ) need not.
