Integer doubleValue() Method in Java

Last Updated : 07 Jul, 2018

The doubleValue() method of Integer class of java.lang package is used to convert the value of the given Integer to a Double type after a widening primitive conversion and returns it. Syntax:

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:

java

// 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:

14.0

Program 2:

java

// 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
