如何在Java中的String.contains（）方法中使用正则表达式

Question

我想检查一个字符串是否按顺序包含单词“ stores”，“ store”和“ product”。无论它们之间是什么。

我尝试使用someString.contains(stores%store%product);并且.contains("stores%store%product");

我是否需要显式声明一个正则表达式并将其传递给方法，还是根本无法传递正则表达式？

public static void main(String[] args) {&nbsp; &nbsp; String test = "something hear - to - find some to or tows";&nbsp; &nbsp; System.out.println("1.result: " + contains("- to -( \\w+) som", test, null));&nbsp; &nbsp; System.out.println("2.result: " + contains("- to -( \\w+) som", test, 5));}static boolean contains(String pattern, String text, Integer fromIndex){&nbsp; &nbsp; if(fromIndex != null && fromIndex < text.length())&nbsp; &nbsp; &nbsp; &nbsp; return Pattern.compile(pattern).matcher(text).find();&nbsp; &nbsp; return Pattern.compile(pattern).matcher(text).find();}1.结果：正确2.结果：正确
