Determining If a String Matches a Pattern Exactly

  

import java.util.regex.Matcher;
import java.util.regex.Pattern;

public class Main {
  public static void main(String[] argv) throws Exception {

    // Compile regular expression
    String patternStr = "b";
    Pattern pattern = Pattern.compile(patternStr);

    // Determine if there is an exact match
    CharSequence inputStr = "a b c";
    Matcher matcher = pattern.matcher(inputStr);
    boolean matchFound = matcher.matches(); 

    // Try a different input
    matcher.reset("b");
    matchFound = matcher.matches(); 

    // Determine if pattern matches beginning of input
    matchFound = matcher.lookingAt();

  }
}
