pattern matcher java example
Example 1: java regex matcher example
import java.util.regex.Pattern;
import java.util.regex.Matcher;
public class MatcherExample {
public static void main(String[] args) {
String text =
"This is the text to be searched " +
"for occurrences of the http:// pattern.";
String patternString = ".*http://.*";
Pattern pattern = Pattern.compile(patternString);
Matcher matcher = pattern.matcher(text);
boolean matches = matcher.matches();
int count = 0;
while(matcher.find()) {
count++;
System.out.println("found: " + count + " : "
+ matcher.start() + " - " + matcher.end());
}
}
}

String emailRegEx = ".+@gmail\\.com$";
Pattern pattern = Pattern.compile(emailRegEx);
List<String> list = new ArrayList();
for (int i = 0; i < num; i++){
String name = scanner.next();
String email = scanner.next();
Matcher matcher = pattern.matcher(email);
if (matcher.find()){
list.add(name);
}
}
Collections.sort(list);
for (String name : list){
System.out.println(name);
}
}
