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
