java类冲突检测源码

以下是一个简单的Java类冲突检测源码示例：

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
import java.util.Set;

public class ClassConflictDetector {

    public static void main(String[] args) {
        List<String> classNames = new ArrayList<>();
        classNames.add("com.example.MyClass");
        classNames.add("com.example.another.MyClass");
        classNames.add("com.example.YetAnotherClass");

        Map<String, Integer> classCounts = new HashMap<>();

        for (String className : classNames) {
            String packageName = getPackageName(className);
            Integer count = classCounts.get(packageName);
            if (count == null) {
                count = 0;
            }
            count++;
            classCounts.put(packageName, count);
        }

        Set<String> packages = classCounts.keySet();
        for (String packageName : packages) {
            Integer count = classCounts.get(packageName);
            if (count > 1) {
                System.out.println("Conflicting classes found in package " + packageName);
            }
        }
    }

    private static String getPackageName(String className) {
        int lastDotIndex = className.lastIndexOf('.');
        if (lastDotIndex == -1) {
            return "";
        }
        return className.substring(0, lastDotIndex);
    }
}

这个示例代码接受一个类名列表，并检查是否有相同包名的类名称。如果有，则输出“Conflicting classes found in package [package name]”消息。
