Java 数组搜索 [英] Java Array Searching

问题描述

在java中一个数组有三个词{'bad','bat','hat'}.我必须编写一个函数，该函数将像字典一样从数组中搜索.

In java an array has three words {'bad','bat','hat'}. I have to write a function which will search like dictionary from array.

示例:如果我搜索 at，那么该函数将返回所有包含 at 的单词(例如 bat 和 hat 将显示在输出中)，如果我搜索单个字符字符，那么它将返回所有具有该字符的单词.Java 中是否有可用的内置函数?

Example: If I search at then the function will return all the words which have at in it (like bat and hat will be shown in the output) and if I search a single character character then it will return all those words which have that character. Is there any built-in function available in Java?

例如:if (string.contains(item1) || string.contains(item2) || string.contains(item3))

推荐答案

您可以流式传输数组，并使用 String::contains.

You could stream the array, and filter using String::contains.

String[] words = {"bad", "bat","hat"};
String filter = "at";

List<String> list = Stream.of(words)
        .filter(word -> word.contains(filter))
        .collect(Collectors.toList());

System.out.println(list);
