Usage

From source file:Main.java

public static void main(String[] args) {

    // get a number as float
    Number x = new Float(123456f);

    // get a number as double
    Number y = new Double(9876);

    // print their value as short
    System.out.println("x as float :" + x + ", x as short:" + x.shortValue());
    System.out.println("y as double:" + y + ", y as short:" + y.shortValue());
