f.format("%021d", commitCounter);
f.flush();
f.close();
final String basename = sb.toString();
return basename;

get Formated Time 
int intTime = (int) timeInSeconds;
final int hours = intTime / 3600;
intTime = intTime % 3600;
final int min = intTime / 60;
intTime = intTime % 60;

int maxValueSize = 0;
Enumeration<Object> keys = myProps.keys();
while (keys.hasMoreElements()) {
    String key = (String) keys.nextElement();
    String value = myProps.getProperty(key);
    if (key.length() > maxKeySize)
        maxKeySize = key.length();
...
StringGetRawView(String string)
Get Raw View 
byte[] bytes = string.getBytes();
StringBuilder sb = new StringBuilder();
Formatter formatter = new Formatter();
for (int i = 0; i < bytes.length; i++) {
    String raw = Integer.toString((bytes[i] & 0xff) + 0x100, 16).substring(1);
