来自数组的布尔值- java中的函数，从命令行输入

import java.util.Scanner;

public class Main {
    public static boolean getBooleanValue(int[] array, int target) {
        for (int num : array) {
            if (num == target) {
                return true;
            }
        }
        return false;
    }

    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        System.out.print("请输入数组元素个数：");
        int n = scanner.nextInt();
        int[] array = new int[n];
        System.out.println("请输入数组元素：");
        for (int i = 0; i < n; i++) {
            array[i] = scanner.nextInt();
        }
        System.out.print("请输入目标值：");
        int target = scanner.nextInt();

        boolean result = getBooleanValue(array, target);
        System.out.println("数组中是否存在目标值：" + result);
    }
}
