Question

1. Assume a double variable named number has been defined. Write a statement that calculates 100 divided by 5 and assigns the result to the number variable.
2. Assume that three double variables named result, number1, and number2 have been defined, and have been assigned values. Write a statement that assigns the value of number1 multiplied by number2 to result.
3. Write a statement that defines a named constant named SPEED. The constant's data type should be int, and its value should be 75.

Answer 1

Answer:

public class num4 {

   public static void main(String[] args) {

//        Question One

       double number = 100/5;

//        Question Two

       double result =0.0;

       double number1 =0.0;

       double number2 =0.0;

       result = number1*number2;

//        Question Three

       final int SPEED =75;

   }

}

Explanation:

As required, the different variables are created in Java programming language.

In question three the keyword final is used to indicate a constant in java since java does not have an implementation for constant values, final and static keywords are used for this purpose
