检查现有数组是否已给定值

const array = [1, 2, 3, 4, 5];
const value = 3;

if (array.includes(value)) {
  console.log('数组包含给定值');
} else {
  console.log('数组不包含给定值');
}

import java.util.ArrayList;

public class Main {
    public static void main(String[] args) {
        ArrayList<Integer> list = new ArrayList<>();
        list.add(1);
        list.add(2);
        list.add(3);
        list.add(4);
        list.add(5);
        
        int value = 3;

        if (list.contains(value)) {
            System.out.println("数组包含给定值");
        } else {
            System.out.println("数组不包含给定值");
        }
    }
}

SELECT * FROM table_name WHERE column_name = '给定值';
