Answer to Question #306606 in Java | JSP | JSF for rushna

Question

A method called absoluteValue, which takes as its only parameter a value of type double, and

returns a value of type double. The parameter represents an arbitrary number, and the value returned

by the method represents the absolute value of this arbitrary number. The absolute value of a number

x, denoted |x|, is x if x is greater than or equal to 0, and -x if x is less than 0. For example, suppose the

following method call is executed:

double value = MathAssignment.absoluteValue(-42.0);

After the execution of the above method call, the value stored in variable value will be 42.0, as the

absolute value of -42 is 42.

3. Now write the main method and call both methods with appropriate arguments. Make sure that you

call both methods with enough valid values to show their

Answer 1

public class MathAssignment{


  public static void main(String args[]) {


        double value = MathAssignment.absoluteValue(Integer.parseInt(args[0]));
        System.out.println(value);
  }
  
  
    static double absoluteValue(double assignment){
        
        if(assignment < 0){
            return assignment * -1;
        }
        return assignment;
    }
}
