## Why is this an issue?

Calling `String.isEmpty()` clearly communicates the code’s intention, which is to test if the string is empty. Using `String.length() == 0` is less direct and makes the code less readable.

## How to fix it

### Code examples

#### Noncompliant code example

    if ("string".length() == 0) { /* … */ } // Noncompliant

    if ("string".length() > 0) { /* … */ } // Noncompliant

#### Compliant solution

    if ("string".isEmpty()){ /* … */ }

    if (!"string".isEmpty()){ /* … */ }
