File Name Matches Type (ARCH4005)

Key java.naming.file-name-matches-type · Severity info · Category naming

In Java a source file’s name should match its primary top-level type. When it doesn’t, navigation and reading the codebase become harder.

Incorrect

Account.java

public class OrderService {   // does not match file name
    void place() { }
}

Correct

OrderService.java

public class OrderService {
    void place() { }
}

Fix

Rename the file to match its primary public type (minus the extension).
