Usage

From source file:Main.java

public static float getMedian(List<Float> values) {
    Collections.sort(values);
    if (values.size() % 2 == 0) {
        return (values.get(values.size() / 2 - 1) + values.get(values.size() / 2)) / 2;
    } else {/*from   www .j av a 2 s. c o  m*/
        return values.get(values.size() / 2);
    }
}

From source file:Main.java

    List<E> list = new ArrayList<E>(c);
    Collections.sort(list);
    return list;//w w  w. j a  v  a 2  s . c  o  m
}

From source file:Main.java

    return list;//from w w w.j  a  va 2s. c  om
}

From source file:Main.java

}

From source file:Main.java

    String flattenedNames = sb.toString();

    if (flattenedNames.length() > 2) {
        // drop the last comma and space
        flattenedNames = flattenedNames.substring(0, flattenedNames.length() - 2);
    }

    return flattenedNames;
}
