public double doubleValue()Parameters: The method does not take any parameter. Return Value: This method returns a numeric value represented by this object after conversion to double type. Below programs illustrate java.lang.Integer.doubleValue() method. Program 1:
// Code to illustrate doubleValue() method
import java.lang.Integer;
class Gfg {
// Driver code
public static void main(String args[])
{
Integer a = new Integer(14);
// Convert Integer number to double value
double b = a.doubleValue();
System.out.println(b);
}
}
Output:
Program 2:
14.0
// Code to illustrate doubleValue() method
import java.lang.Integer;
class Gfg {
// Driver code
public static void main(String args[])
{
Integer a = new Integer(120);
// Convert Integer number to double value
double b = a.doubleValue();
System.out.println(b);
}
}
Output:
120.0
