Broad Wildcard Import (ARCH4192)

Key java.quality.wildcard-import · Severity warning · Category quality

Wildcard (*) imports pollute the namespace and hide where a type comes from, setting up name collisions. Import only the types you actually use, explicitly.

Incorrect

import java.util.*;

List<String> names = new ArrayList<>();

Correct

import java.util.List;
import java.util.ArrayList;

List<String> names = new ArrayList<>();

Fix

Replace wildcard imports with explicit imports of only the types actually used.
