Java中用于字母和数字的模式匹配

Question

I am doing a simple pattern matching, which is not working. Please help

The string is:

The number *TER8347834SC* has problems.

The String contains a number TER8347834SC which may change with different messages, so i need to use regex to match this number while comparing the String. So while comparing String I am using the regex as [A-Z0-0] for TER8347834SC which doesn't match.

I know this is quite simple, but i tried many times, please help me in this.

Answer 1

仅当消息始终与您提到的相同时，您的模式才应该像这样：

String pattern = "The number (.*) has problems.";

Answer 2

Think you mean this,

"\\b[A-Z0-9]+\\b"

Note that \\\\b word boundary is a much needed one.

Answer 3

尝试使用这个：

([A-Z]+[0-9]+)
