java - 在Java中查找数组中的多个搜索结果

Question

我制作了一个由名字组成的数组。我有一个搜索函数，可以搜索数组的元素，并且工作正常。但是，对于数组的多个元素，我不知道如何打印返回了多少个结果。例如，如果在我的示例中找到“John”(确实如此)，我不知道如何表明找到了多个结果。请有人帮助我。我需要让“计数”为找到的每个结果增加 1 倍。这是我的代码:`

import java.util.*;

class Search {
    public static void main(String[] args) {

    Scanner search = new Scanner(System.in); 
       String[] firstName = new String[]{"John", "Thomas", "Samuel", "Chris", "Daniel", "Joey", "David", "Joshua", "Michael", "John"};
       Arrays.sort(firstName);
       System.out.print("Enter a search term: ");
       String name = search.next();

       int i;

       boolean foundIt = false;

    search:
       for (i = 0; i < firstName.length; i++) {
           if (firstName[i] == name) {
                   foundIt = true;

               }
           }


       if (foundIt = true){
            System.out.println("Your search term of " + name + " produced " + count + " search results");
       }

       else {
           System.out.println("Your search term of " + name + " did not return any results");
       }
   }
}

您可以将 boolean 型foundIt更改为int count，并在将foundIt设置为true的位置递增。

所以类似:

int count = 0;

search:
   for (i = 0; i < firstName.length; i++) {
       if (firstName[i] == name) {
               count++;
       }
   }


   if (count > 0){
        System.out.println("Your search term of " + name + " produced " + count + " search results");
   }

   else {
       System.out.println("Your search term of " + name + " did not return any results");
   }
