如何创建正则表达式以匹配Java中单词的结尾？

Question

Need regex for matching { character and every line that ends with this character. For example: (isMoving){

Tried:

^.?\{$

but it works only for single {

Answer 1

.? means zero or one character. You want to match zero or more. Also the curly brace is a special regex character that is used for quantifying the occurrences of a certain pattern, and so it should be escaped:

^.*\{$

Answer 2

The Java string representation of the regex you want is ".*\\\\{" for use like

if (lineText.matches(".*\\{")) { ... }

A good place to experiment with such things is RegexPlanet's Java page
