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);
}
}
