查看ArrayList是否包含Java中的对象的最有效方法

import java.util.ArrayList;

public class Main {
    public static void main(String[] args) {
        ArrayList<String> arrayList = new ArrayList<>();
        arrayList.add("apple");
        arrayList.add("banana");
        arrayList.add("orange");

        String target = "banana";

        boolean containsTarget = arrayList.contains(target);

        if (containsTarget) {
            System.out.println("ArrayList包含目标对象");
        } else {
            System.out.println("ArrayList不包含目标对象");
        }
    }
}
