The doubleValue() method of Byte class is a built in method in Java which is used to return the value of this Byte object as double.
Syntax
ByteObject.doubleValue()
Return type: It returns the value of ByteObject as double.
Below is the implementation of doubleValue() method in Java:
Example 1:
// Java code to demonstrate// Byte doubleValue() method class GFG { public static void main(String[] args) { // byte value byte a = 17; // wrapping the byte value // in the wrapper class Byte Byte b = new Byte(a); // doubleValue of the Byte Object double output = b.doubleValue(); // printing the output System.out.println("Double value of " + a + " is : " + output); }} |
Output:
Double value of 17 is : 17.0
Example 2:
// Java code to demonstrate// Byte doubleValue() method class GFG { public static void main(String[] args) { String value = "17"; // wrapping the byte value // in the wrapper class Byte Byte b = new Byte(value); // doubleValue of the Byte Object double output = b.doubleValue(); // printing the output System.out.println("Double value of " + b + " is : " + output); }} |
Output:
Double value of 17 is : 17.0
