Question

Please help in Java:

Create an array to hold 10 FeetInches objects. Input is from the keyboard (20 ints). To get the correct output you MUST use this input: 56 34 4 67 3 4 45 5 11 21 84 45 44 5 8 11 23 2 20 19

What I have so far :

public static class FeetInches {
private int feet;
private int inches;

public FeetInches()
{//write the code for the default constructor here
feet = 0;
inches = 0;
}
public FeetInches(int f, int i)
{
feet = f + i/12;
inches = i%12;
  
}
public void setFeet(int f){
feet = f;

}
public void setInches(int i){
feet = feet + i/12;
inches = i%12;
}
public int getFeet(){
return feet;
}
public int getInches(){
return inches;
}
  

  
public String toString()
{

return " Feet: " + feet + " Inches: " + inches ;
  
  

}
  
}
public static void main(String[] args) {
Scanner keyboard = new Scanner(System.in);
int feet, inch, input;
//create an array to hold 10 FeetInches objects
FeetInches[] ft = new FeetInches [10];
//input 20 ints from the keyboard.
System.out.println("Enter 20 integers: ");
input=keyboard.nextInt();
  
feet=.nextInt();
inch=keyboard.nextInt();
//you MUST enter the ones I gave you to get the correct output
//input and output is in answers,txt in the module
for (int i=0; i<20; i++){
System.out.println("Feet: "+ feet + " Inches: "+inch);
}
}
}
  

Also need to do the same thing again BUT with an ArrayList.

Thanks!

Explanation / Answer

Hi

I have modifed the code and highlighted the code changes below.

FeetInches.java

import java.util.ArrayList;
import java.util.Scanner;

public class FeetInches {
private int feet;
private int inches;
public FeetInches()
{//write the code for the default constructor here
feet = 0;
inches = 0;
}
public FeetInches(int f, int i)
{
feet = f + i/12;
inches = i%12;
  
}
public void setFeet(int f){
feet = f;

}
public void setInches(int i){
feet = feet + i/12;
inches = i%12;
}
public int getFeet(){
return feet;
}
public int getInches(){
return inches;
}
  
  
public String toString()
{

return " Feet: " + feet + " Inches: " + inches ;
  
  

}
  

public static void main(String[] args) {
Scanner keyboard = new Scanner(System.in);
int feet, inch, input;
//create an array to hold 10 FeetInches objects
ArrayList<FeetInches> list = new ArrayList<FeetInches>();
//input 20 ints from the keyboard.
System.out.println("Enter 20 integers: ");
for(int i=0; i<10; i++){
  
feet=keyboard.nextInt();
inch=keyboard.nextInt();
FeetInches f = new FeetInches(feet, inch);
list.add(f);
}
//you MUST enter the ones I gave you to get the correct output
//input and output is in answers,txt in the module
for (int i=0; i<list.size(); i++){
   FeetInches f = list.get(i);
System.out.println("Feet: "+ f.feet + " Inches: "+f.inches);
}
}
}
  

Output:

Enter 20 integers:
56 34 4 67 3 4 45 5 11 21 84 45 44 5 8 11 23 2 20 19
Feet: 58 Inches: 10
Feet: 9 Inches: 7
Feet: 3 Inches: 4
Feet: 45 Inches: 5
Feet: 12 Inches: 9
Feet: 87 Inches: 9
Feet: 44 Inches: 5
Feet: 8 Inches: 11
Feet: 23 Inches: 2
Feet: 21 Inches: 7
