    {

    double x=3.0; / /define variable x.

    public static void sendDouble (double x) / /define method sendDouble.

    {

    x=9.6; / /change variable value

    System. out. print ("The value of x variable is : "+x); / /print value.

    }

    public static void main (String[] args) / /define main method

    {

    sendDouble (0.0); / /calling function

    }

    }

    Output:

    The value of x variable is : 9.6

    Explanation:

    The explanation of the above java program can be define as follows:

    In the above java program a class is define that is "DataTransmitter" inside a class a double variable that is x is define which contain a double value that is "3.0". In this class, a static method "sendDouble () " is defined. in the method, a double parameter is passed. inside a method, we change the variable value and print its value. In main method is a sendDouble () function is called. In calling time a double value is passed in the function parameter.
