Question

Write an if/else statement that compares the double variable pH with 7.0 and makes the following assignments to the bool variables neutral, base, and acid: a. false, false, true if pH is less than 7 b. false, true, false if pH is greater than 7 c. true, false, false if pH is equal to 7.

Answer 1

Answer

       if (pH<7.0){

           neutral=false;

           base=false;

           acid=true;

       }

       else if (pH>7.0){

           neutral=false;

           base=true;

           acid=false;

       }

       else if (pH==7.0){

           neutral=true;

           base=false;

           acid=false;

       }

A complete java program that prompts a user for the pH value is provided in the explanation section

Explanation:

import java.util.Scanner;

public class ANot {

   public static void main(String[] args) {

      Scanner in = new Scanner(System.in);

       System.out.println("Enter a value for the pH");

       boolean neutral, base, acid;

       double pH = in.nextDouble();

       if (pH<7.0){

           neutral=false;

           base=false;

           acid=true;

       }

       else if (pH>7.0){

           neutral=false;

           base=true;

           acid=false;

       }

       else if (pH==7.0){

           neutral=true;

           base=false;

           acid=false;

       }

}
