regex-Simple Regular Expression parsing problem

Regexphpjava

The following is the other side to the parsing template PHP regular, want to use in Java, because it is a small white, hope to get everyone's help, thanks, thank you!!
My question: I understand preg_replace (); This method requires three parameters, the first is a regular expression, the second is a replacement string, the third is the template code, and finally the replacement template code is returned. In Java, the first parameter error, do not know if the syntax is not correct, if in Java and how to use, I hope the heroes pointing!!
/**
* Parsing templates
*
* @param $str Template content
* @return Ture
*/
Public Function Template_parse ($STR) {
$str = Preg_replace ("/{view\s+ (. +)}/", " ", $str);
$str = Preg_replace ("/{template\s+ (. +)}/", " ", $str);
$str = Preg_replace ("/{include\s+ (. +)}/", " ", $str);
return $str;
}
