HELP IN JAVA: Write a program that inputs feet and inches, creates a FeetAndInch

Question

HELP IN JAVA:

Write a program that inputs feet and inches, creates a FeetAndInches object, puts it in a Node, and then adds (prepends) these nodes to a list. Input is from the keyboard. Files Node.java and FeetAndInches.java have already been uploaded, you just have to write the main method.

public static void main(String[] args) {
Scanner keyboard = new Scanner (System.in);
int feet, inches;


Node head=null;
System.out.println("Please enter the number of feet and inches separated by space, enter 0 0 to quit");
feet = keyboard.nextInt();
inches = keyboard.nextInt();
while( )
{

System.out.println("Please enter the number of feet and inches separated by space, enter 0 0 to quit");
feet = keyboard.nextInt();
inches = keyboard.nextInt();
}
PrintList(head);

}
  
  
public static void PrintList(Node head)
{ Node curr=head; FeetAndInches m;
while(curr !=null)
{m= (FeetAndInches) curr.item;
System.out.println(m);
curr=curr.next;
}//end while
}
}

Explanation / Answer

public static void main(String[] args) {

Scanner keyboard = new Scanner (System.in);

int feet, inches;

Node head=null;

System.out.println("Please enter the number of feet and inches separated by space, enter 0 0 to quit");

feet = keyboard.nextInt();

inches = keyboard.nextInt();

while(!(feet==0 && inches==0))

{

// create a temporary node

Node temp=new Node(new FeetAndInches(feet, inches));

temp.next=null;

// if the list is empty

if(head==null)

head=temp;

// otherwise add the node tot the beginning of the list

else

{

temp.next = head;

head = temp;

}

System.out.println("Please enter the number of feet and inches separated by space, enter 0 0 to quit");

feet = keyboard.nextInt();

inches = keyboard.nextInt();

}

PrintList(head);

}
