The doubleValue() method of Double class is a built in method to return the value specified by the calling object as double after type casting. Syntax:
DoubleObject.doubleValue()
Return Value: It return the value of DoubleObject as double. Below programs illustrate doubleValue() method in Java: Program 1:
Java
// Java code to demonstrate
// Double doubleValue() method
class GFG {
public static void main(String[] args)
{
// Double value
Double a = 17.47;
// wrapping the Double value
// in the wrapper class Double
Double b = new Double(a);
// doubleValue of the Double Object
double output = b.doubleValue();
// print doubling the output
System.out.println("Double value of "
+ b + " is : " + output);
}
}
Output:
Double value of 17.47 is : 17.47
Program 2:
Java
// Java code to demonstrate
// Double doubleValue() method
class GFG {
public static void main(String[] args)
{
String value = "54.1";
// wrapping the Double value
// in the wrapper class Double
Double b = new Double(value);
// doubleValue of the Double Object
double output = b.doubleValue();
// print doubling the output
System.out.println("Double value of "
+ b + " is : " + output);
}
}
Output:
Double value of 54.1 is : 54.1
