Question

All JAVA code

6.2.2:

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

5' 8"

Hint: Use \" to print a double quote

Sample program:

import java.util.Scanner;

public class HeightPrinter {

/* Your solution goes here */

public static void main (String [] args) {
printFeetInchShort(5, 8);
System.out.println("");

return;
}
}

6.4.1:

Define stubs for the methods called by the below main(). Each stub should print "FIXME: Finish methodName()" followed by a newline, and should return -1. Example output:

FIXME: Finish getUserNum()
FIXME: Finish getUserNum()
FIXME: Finish computeAvg()
Avg: -1

Sample program:

import java.util.Scanner;

public class MthdStubsStatistics {

/* Your solution goes here */

public static void main() {
int userNum1 = 0;
int userNum2 = 0;
int avgResult = 0;

userNum1 = getUserNum();
userNum2 = getUserNum();

avgResult = computeAvg(userNum1, userNum2);

System.out.println("Avg: " + avgResult);

return;
}
}

6.2.2:

Program:

/import the utilities package import j /*HeightPrinter class to display the height in shorthand notation*/ public class HeightPrinter ava.util.* /*static method that accept two integer variables numFeet and numInches and display height in short hand notation */ public static void printFeetInchShort(int numFeet, int numInches) System. out.println (numFeet+ "'"+ numInches"\"" /* main method */ public static void main (String [] args) //variable declaration int numFeet, numInches; //Scanner class scanner sc=new Scanner (System.in); *Prompt the user to enter number of feet and number of inches System. out.println(" Enter the number of feet: numFeet-3c.nextInt ); System.out.println (" Enter the number of Inches:") numi nches = sc.next Int(); //Display the output System. out.print("In shorthand notation the height is:") printFeet InchsShort (numFeet, numInches) //clsing the scanner class sc.close System.out.println(" "):

Sample Output:

Enter the number of feet: Enter the number of Inches: 8 In shorthand notation the height is: 5'8

Code to be copied by the user:

/*import the utilities package*/

import java.util.*;

/*HeightPrinter class to display the height in shorthand notation*/

public class HeightPrinter

{

     /*static method that accept two integer variables numFeet and numInches

     and display height in short hand notation */

     public static void printFeetInchShort(int numFeet, int numInches)

     {

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

     }

     /* main method */

     public static void main (String[] args)

     {

          //variable declaration

          int numFeet, numInches;

          //Scanner class

          Scanner sc=new Scanner(System.in);

          /*Prompt the user to enter number of feet and number of inches*/

          System.out.println("Enter the number of feet: ");

          numFeet = sc.nextInt();

          System.out.println("Enter the number of Inches: ");

          numInches = sc.nextInt();

          //Display the output

          System.out.print("In shorthand notation the height is: ");

          printFeetInchShort(numFeet,numInches);

          //clsing the scanner class

          sc.close();

          System.out.println("");
