Usage

From source file:Main.java

public static void main(String[] args) {
    String testString = " weight 600 KG AND HEIGHT 84900 CM";
    Pattern pattern = Pattern.compile("(?<=HEIGHT)\\s*([0-9]+)\\s*(?=CM)");
    Matcher matcher = pattern.matcher(testString);
    while (matcher.find()) {
        System.out.println("Height: '" + matcher.group(1) + "'");
    }/*from www .j  a v a 2  s .c o m*/
}

From source file:Main.java

public static void main(String[] argv) throws Exception {
    // Use COMMENTS but include a character class with a space

    CharSequence inputStr = "a b";
    String patternStr = "a b";

    // Compile without comments
    Pattern pattern = Pattern.compile(patternStr);
    Matcher matcher = pattern.matcher(inputStr);
    boolean matchFound = matcher.matches();

    // Compile with comments
    pattern = Pattern.compile(patternStr, Pattern.COMMENTS);
    matcher = pattern.matcher(inputStr);
    matchFound = matcher.matches();/*from  w  w  w .  ja v a  2s . c om*/

    patternStr = "a  [\\ ]  b";
    pattern = Pattern.compile(patternStr, Pattern.COMMENTS);
    matcher = pattern.matcher(inputStr);
    matchFound = matcher.matches();
}

From source file:Main.java

public static void main(String args[]) {
