数组—查找

.顺序查找，二分查找

.字符串的比较用equals ()

.引擎，改变参数值，触发程序

import java.util.Scanner;

public class lianxi {

    public static void main(String[] args) {
        
    //顺序查找，二分查找
        //顺序查找
      String[] names ={"白眉鹰王","金毛狮王","紫衫龙王","青逸蝠王"};
      Scanner myScanner = new Scanner(System.in);
      System.out.println("请输入名字");
      String  findName = myScanner.next();
      int index = -1;
         //字符串的比较用equals
        for(int i = 0;i< names.length;i++){
            if(findName.equals(names[i])){
                System.out.println("恭喜你找到了"+findName);
                System.out.println("下标为"+i);
               index =i;
                break;//退出

            }

        }if(index ==-1){
            System.out.println("很遗憾，没有找到");
        }
  }}
