Difference Between Checked and Unchecked Exception in Java

In this post, we will understand the difference between checked and unchecked exceptions in Java.

Checked Exceptions

• They occur at compile time.

• The compiler checks for a checked exception.

• These exceptions can be handled at the compilation time.

• It is a sub-class of the exception class.

• The JVM requires that the exception be caught and handled.

• Example of Checked exception- ‘File Not Found Exception’

Unchecked Exceptions

• These exceptions occur at runtime.

• The compiler doesn’t check for these kinds of exceptions.

• These kinds of exceptions can’t be caught or handled during compilation time.

• This is because the exceptions are generated due to the mistakes in the program.

• These are not a part of the ‘Exception’ class since they are runtime exceptions.

• The JVM doesn’t require the exception to be caught and handled.

• Example of Unchecked Exceptions- ‘No Such Element Exception’
