Question

Answer in JAVA

1.

Complete the method definition to output the hours given minutes. Output for sample program:

3.5

import java.util.Scanner;
public class HourToMinConv {
   public static void outputMinutesAsHours(double origMinutes) {

      /* Your solution goes here */

   }

   public static void main (String [] args) {
      Scanner scnr = new Scanner(System.in);
      double minutes;

      minutes = scnr.nextDouble();

      outputMinutesAsHours(minutes); // Will be run with 210.0, 3600.0, and 0.0.
      System.out.println("");
   }
}

2.

Define a method printFeetInchShort, with int parameters numFeet and numInches, that prints using ' and " shorthand. End with a newline. Ex: printFeetInchShort(5, 8) prints:

5' 8"

Hint: Use \" to print a double quote.

import java.util.Scanner;

public class HeightPrinter {

   /* Your solution goes here */

   public static void main (String [] args) {
      Scanner scnr = new Scanner(System.in);
      int userFeet;
      int userInches;

      userFeet = scnr.nextInt();
      userInches = scnr.nextInt();

      printFeetInchShort(userFeet, userInches); // Will be run with (5, 8), then (4, 11)
   }
}

3.

Write a method printShampooInstructions(), with int parameter numCycles, and void return type. If numCycles is less than 1, print "Too few.". If more than 4, print "Too many.". Else, print "N: Lather and rinse." numCycles times, where N is the cycle number, followed by "Done.". End with a newline. Example output with input 2:

1: Lather and rinse.
2: Lather and rinse.
Done.
 

Hint: Declare and use a loop variable.

import java.util.Scanner;

public class ShampooMethod {

   /* Your solution goes here */

   public static void main (String [] args) {
      Scanner scnr = new Scanner(System.in);
      int userCycles;

      userCycles = scnr.nextInt();
      printShampooInstructions(userCycles);
   }
}

import java.util.Scanner;

public class HourToMinConv {
    public static void outputMinutesAsHours(double origMinutes) {
        System.out.print(origMinutes / 60);
    }

    public static void main(String[] args) {
        Scanner scnr = new Scanner(System.in);
        double minutes;

        minutes = scnr.nextDouble();

        outputMinutesAsHours(minutes); // Will be run with 210.0, 3600.0, and 0.0.
        System.out.println("");
    }
}

import java.util.Scanner;

public class HeightPrinter {

        System.out.println(numFeet + "' " + numInches + "\"");
    }

    public static void main(String[] args) {
        Scanner scnr = new Scanner(System.in);
        int userFeet;
        int userInches;

        userFeet = scnr.nextInt();
        userInches = scnr.nextInt();

        printFeetInchShort(userFeet, userInches); // Will be run with (5, 8), then (4, 11)

import java.util.Scanner;

public class ShampooMethod {

    static void printShampooInstructions(int numCycles) {
        if (numCycles < 1) {
            System.out.println("Too few..");
        } else if (numCycles > 4) {
            System.out.println("Too many..");
        } else {
            for (int i = 1; i <= numCycles; ++i) {
                System.out.println(i + ": Lather and rinse.");
            }
            System.out.println("Done.");
        }
    }

    public static void main(String[] args) {
        Scanner scnr = new Scanner(System.in);
        int userCycles;

        userCycles = scnr.nextInt();
        printShampooInstructions(userCycles);
    }
}

2 1: Lather and rinse. 2: Lather and rinse. Done. Process finished with exit code 0
