数组键盘初始化赋值及线性查找索引

JAVA：数组键盘初始化赋值及线性查找索引

package com.chj.contact;

import java.util.Scanner;

public class Search {
	public static void main(String[] args) {
		System.out.println("请输入数组长度：");
		Scanner scan = new Scanner(System.in);
		int k = scan.nextInt();
		int[] arr = new int[k];
		System.out.println("请给数组赋值：");
		// 通过键盘给数组赋值
		for (int i = 0; i < k; i++) {
			Scanner scan1 = new Scanner(System.in);
			arr[i] = scan1.nextInt();
		}
		// 查找值
		System.out.println("请输入查找值：");
		Scanner scan1 = new Scanner(System.in);
		int destination = scan1.nextInt();
		// 进行索引
		boolean isFlag = true;
		for (int i = 0; i < arr.length; i++) {
			if (arr[i] == destination) {
				System.out.println("该数" + destination + "存在\t" + "索引为：" + i);
				isFlag = false;
				break;
			}
		}
		if (isFlag) {
			System.out.println("该数" + destination + "不存在\t");
		}
