Answer:
The program to this question can be given as:
Program:
public class Telephone //define class Telephone.
{
public static void printNumber(String s) //define method
{
System.out.print(s); //print value.
}
public static void main(String[] args) //define main method
{
String s ="ABCD"; //define variable s and assign value.
printNumber(s); //calling function.
}
}
Output:
ABCD
Explanation:
In above java program we define a class that is "Telephone". Inside the class we define a function that is "printNumber" in the function we pass one string value that is "s" and the function will not return any value, because we use return type void. In this function we print pass variable value.
Then we define the main method inside the method we define a string variable and assign a value that is s = "ABCD" and call the function that prints its value.
