Returns the value of this Double as a float after a narrowing primitive conversion.

Usage

From source file:Main.java

From source file:Main.java

public static void main(String[] args) {
    Integer intObj = Integer.valueOf(100);

    // Gets byte from Integer
    byte b = intObj.byteValue();

    // Gets double from Integer
    double dd = intObj.doubleValue();
    System.out.println("intObj = " + intObj);
    System.out.println("byte from  intObj = " + b);
    System.out.println("double from  intObj = " + dd);

    // Creates a Double object
    Double doubleObj = Double.valueOf("123.45");

    // Gets different types of primitive values from Double
    double d = doubleObj.doubleValue();
    float f = doubleObj.floatValue();
    int i = doubleObj.intValue();
    long l = doubleObj.longValue();

    System.out.println("doubleObj = " + doubleObj);
