【正则表达式】以 lbl_ 开头，以 } 或 | 符号结尾的字符串，用正则表达式怎么写？程序语言是JAVA

Answer 1

这个是正则匹配: ^lbl\_.*(\}|\|)$
java程序如下：
public class hello {

/**
* @param args
*/
public static void main(String[] args) {
String a="lbl_dddddddddddd }";
String b="lbl_dddddddddddddddd|";
String c=" d";

String regEx ="^lbl_.*(}||)$";

Pattern pattern = Pattern.compile(regEx);
Matcher matchera = pattern.matcher(a);
Matcher matcherb = pattern.matcher(b);
Matcher matcherc = pattern.matcher(c);
boolean rsa = matchera.matches();
boolean rsb = matcherb.matches();
boolean rsc = matcherc.matches();
System.out.println(rsa);
System.out.println(rsb);
System.out.println(rsc);

}}

result:
true
true
false
