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.

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
