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() methodclass 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() methodclass 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
