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

Usage

From source file:Main.java

public static void main(String[] args) {
    Double doubleObject = new Double("10.01");
    byte b = doubleObject.byteValue();
    System.out.println("byte:" + b);
}

From source file:Main.java

public static void main(String[] args) {
    Double dObj = new Double("10.50");
    byte b = dObj.byteValue();
    System.out.println(b);/*from   w ww  .  jav a  2 s . c om*/

    short s = dObj.shortValue();
    System.out.println(s);

    int i = dObj.intValue();
    System.out.println(i);

    float f = dObj.floatValue();
    System.out.println(f);

    double d = dObj.doubleValue();
    System.out.println(d);
}
