如何检查字符串是否包含搜索项

Question

我有一个String和一个String[]充满搜索项目.

如何检查我是否String包含所有搜索项？

这是一个例子:

情况1:

String text = "this is a stupid test";
String[] searchItems = new String[2];
searchItems[0] = "stupid";
searchItems[1] = "test";

案例2:

String text = "this is a stupid test";
String[] searchItems = new String[2];
searchItems[0] = "stupid";
searchItems[1] = "tes";

在情况1中,该方法应该返回true,但在情况2中该方法应该返回false.

Answer 1

您可以使用正则表达式中的单词边界来执行此操作:

boolean result = true;
for (String item : searchItems) {
    String pattern = ".*\\b" + item + "\\b.*";
    // by using the &&, result will be true only if text matches all patterns.
    result = result && text.matches(pattern);
}

边界确保只有在文本中出现整个单词时才匹配搜索项.所以,"tes"不会匹配"test"因为"\btes\b"不是子串"\btest\b".
