A regular expression, specified as a string, must first be compiled into an instance of this class. The resulting pattern can then be used to create a
Matcher object that can match arbitrary
A typical invocation sequence is thus
Pattern p = Pattern.compile("a*b"); Matcher m = p.matcher("aaaaab"); boolean b = m.matches();
Example
import java.util.regex.*;
class Demo
{
public static void main(String[] args)
{
String p1="[7-9]{1}[0-9]{9}";
Pattern p = Pattern.compile(p1);
Matcher m = p.matcher("9909556848");
if( m.matches())
{
System.out.println("Match");
}
else
{
System.out.println("Not Match");
}
}
}
