Usage

From source file:Main.java

public static void main(String[] args) {

    // get a number as integer
    Number x = new Integer(123456);

    // get a number as float
    Number y = new Float(9876f);

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

}

From source file:Main.java

public static void main(String[] argv) {

    List<Number> numlist = new ArrayList<Number>();

    numlist.add(new Integer(123));
    numlist.add(new Float(123));
}

From source file:Main.java

public static void main(String[] argv) throws Exception {
    JFormattedTextField tft2 = new JFormattedTextField(new DecimalFormat("#.0"));
    tft2.setValue(new Float(123.4F));

    // Retrieve the value from the text field
    Float floatValue = (Float) tft2.getValue();

}

From source file:Test.java

public static void main(String[] args) {
    ArrayList<Integer> a1 = new ArrayList<>();
    a1.add(new Integer(1));
    a1.add(2);//from   w  w  w.ja  va  2  s  .  c o m
