其中有一个常用的编程思想：
由于是遍历查找，不能用if-else来输出没有找到，而应该设置一个索引index，如果找到就将index的值设置成下标的值，如果遍历结束后index仍为初始值，才是没有找到

import java.util.Scanner;
public class SeqSearch {

	public static void main(String[] args) {
		String[] names = {"liming", "jenny", "danny", "monster"};
		Scanner myScanner = new Scanner(System.in);
		int index = -1;
		System.out.print("please enter the name:");

		String findName = myScanner.next();
		for (int i = 0; i < names.length; i++) {
			if (findName.equals(names[i])) {
				index = i;
				System.out.println("find! the position is " + index);
				break;
			}
			// else{
			// 	System.out.print("not find!");
			// }
		}
		if (index == -1) {
			System.out.println("sorry, not find!");
		}

	}
