Reading Stack Traces

Learn how to read stack traces to debug Java programs effectively.

Intro

When an exception is not caught, Java prints a stack trace. It shows the error type and the chain of method calls that led to it.

Stack trace format

A stack trace usually has:

  • First line: exception type and message.
  • Following lines: methods and file:line where the error traveled.
