# Comparing References Inspection Sample [![JetBrains IntelliJ Platform SDK Docs](https://jb.gg/badges/docs.svg)][docs]
*Reference: [Code Inspections in IntelliJ SDK Docs][docs:code_inspections]*

## Quickstart

Comparing References Inspection Sample demonstrates the implementation of the [Code Inspections][docs:code_inspections] feature for Java classes.

The plugin inspects your Java code and highlights any fragments containing the comparison of two `String` or `Date` variables.
If such a check finds a comparison using the `==` or !`=` operators instead of the `.equals()` method, the plugin proposes a *quick-fix* action.
