From source file:Main.java

public static void main(String[] args) {
    CharSequence inputStr = "quit";
    String patternStr = "q";
    String replacementStr = "s";

    Pattern pattern = Pattern.compile(patternStr);

    Matcher matcher = pattern.matcher(inputStr);
    String output = matcher.replaceAll(replacementStr);
}

From source file:Main.java

    Scanner scanner = new Scanner(s);

    System.out.println(scanner.hasNext(Pattern.compile(".com")));

    System.out.println(scanner.hasNext(Pattern.compile("1")));

    // print the rest of the string
    System.out.println(scanner.nextLine());

    scanner.close();/*from ww  w. ja v  a 2 s.c  o  m*/
}
