在Java中,如何检查集合是否包含特定类的实例？

import java.util.List;
import java.util.stream.Collectors;

public class Main {
    public static void main(String[] args) {
        List<Object> list = new ArrayList<>();
        list.add(new MyClass());
        list.add(new AnotherClass());

        boolean containsMyClass = list.stream()
                .anyMatch(obj -> obj instanceof MyClass);

        System.out.println("Contains MyClass: " + containsMyClass);
    }
}

class MyClass {
}

class AnotherClass {
}

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

public class Main {
    public static void main(String[] args) {
        List<Object> list = new ArrayList<>();
        list.add(new MyClass());
        list.add(new AnotherClass());

        boolean containsMyClass = false;
        for (Object obj : list) {
            if (obj instanceof MyClass) {
                containsMyClass = true;
                break;
            }
        }

        System.out.println("Contains MyClass: " + containsMyClass);
    }
}

class MyClass {
}

class AnotherClass {
}
