Write the code for invoking a static method named sendDouble, provided by the DataTransmitter class. There is one double argument for this method. Assume that a double variable called x has already been declared and initialized to some value. Use this variable's value as an argument in your method invocation.

The program to this question as follows:

Program:

public class DataTransmitter / /defining class

{

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.
