检查ArrayList中是否存在值

import java.util.ArrayList;

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

        String valueToCheck = "banana";
        boolean containsValue = arrayList.contains(valueToCheck);

        if (containsValue) {
            System.out.println("ArrayList中存在值：" + valueToCheck);
        } else {
            System.out.println("ArrayList中不存在值：" + valueToCheck);
        }
    }
