Return double value as byte, double, float, int, long, short

byte byteValue()
Returns a byte (by casting to a byte).
double doubleValue()
Returns the double value of this Double object.
float floatValue()
Returns the float value of this Double object.
int intValue()
Returns the value of this Double as an int (by casting to type int).
long longValue()
Returns the value of this Double as a long (by casting to type long).
short shortValue()
Returns the value of this Double as a short (by casting to a short).

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

    short s = doubleObject.shortValue();
    System.out.println("short:"+s);

    int i = doubleObject.intValue();
    System.out.println("int:"+i);

    float f = doubleObject.floatValue();
    System.out.println("float"+f);

    double d = doubleObject.doubleValue();
    System.out.println("double:"+d);

    long l = doubleObject.longValue();
    System.out.println("long:"+l);
  }
}

The output: 


byte:10
short:10
int:10
float10.01
double:10.01
long:10
