Checked vs. Unchecked Exceptions

Difference between Exceptions

Imagine there are two types.
of potential problems ⚠️
in any construction project:
Foreseeable Risks and
Unforeseeable Accidents.

Checked Exceptions are the
Foreseeable Risks which the.
java compiler is able to detect.

Unchecked Exceptions are the
Unforeseeable accidents or.
programmer errors that are
produced while the JVM is
being run.

This is how differ the
Compiler VS Runtime Error.

Common Checked Exceptions

IOException, SQLException, FileNotFoundException, InterruptedException.

Common Unchecked Exceptions

NullPointerException, ArrayIndexOutOfBoundsException, ArithmeticException, ClassCastException.
