Java Double class :

Java Double class encapsulates a double value. It defines several constants. The largest and smallest values are saved in MAX_VALUE and MIN_VALUE. The constant NaN (Not a Number) indicates that a value is not a number. If you divide a double number by zero, the result is NaN. This class defines these constructors:

Double(double d)

Double(String str)

Here, d is a double value to be encapsulated in a Double object. In the last form, str is the string representation of a double value.

EX :


 


Output :
Object d1 = 6.876423654563E8
Object d2 = 686748.0
Minimum Value of Double = 4.9E-324
Maximum Value of Double = 1.7976931348623157E308
Byte value of Double = -3
int value of Double = 687642365
Float value of Double = 6.8764237E8
Double value from the string “765.89”=765.89
