不知道怎么更正确地问,所以会尽我所能.
我们正在搜索一个示例字符串,另一个模式字符串:
我需要一些方法来弄清楚示例是否包含模式(我想到的是像example.indexOf(pattern)> - 1)
Pattern = "b*b"
Example = "gjsdng" - false;
Example = "bob" - true;
Example = "bab" - true;
Example = "gdfgbUbfg" - true;

您可以使用带有正则表达式模式的String#matches(regex)方法.*?b.b.*来匹配文本.
System.out.println("gjsdng".matches(".*?b.b.*")); //false
System.out.println("bob".matches(".*?b.b.*")); //true
System.out.println("bab".matches(".*?b.b.*")); //true
System.out.println("gdfgbUbfg".matches(".*?b.b.*")); // true
