Why the getmem_id is not working for this linked list Java program?

[Nora Morris]

public class LinkedlistQueue {

Node first;

Node last;

public LinkedlistQueue(){

first=null;

last= null;

}

public void insert (int mem_id, int book_id){

Node node = new Node(mem_id, book_id);

if(last==null && first==null){

last= first= node;

last.next= last;

}else{

node.next= first;

last.next= node;

last=node;

}

}

public void enQueue(int mem_id, int book_id){

insert(mem_id, book_id);

System.out.println(mem_id + " is added to the queue");

}

public void deQueue(){

if(isEmpty()){

System.out.println("");

System.out.println("All members are successfully completed");

}else{

Node node = delete();

System.out.println(node.getmem_id()+ " has been removed from the list");

}

}

}

Does the program / classes compile?

else{
 
Node node = delete();
 
System.out.println(node.[b]getmem_id()[/b]+ " has been removed from the list");

On this particular code, getmem_id() is not working. I developing a library management system here. but i'm confused why that getmem_it is not working. I need to get member id to proceed my system to next level.

Please tell us what you did to compile and run the code, what output you expected and what output you got. If you got error messages, post them and any stack traces.

getmem_id() is not working

Please explain.  If there are compiler errors, copy the full text and paste it here.
If the results are not what you want, show the current results and describe what the desired results should be.

I want to get the member id. that's why i used getmem_id() method. but in system it showing red underlined error. how do I implement the get method to retrieve the member id while user entering on the keyboard

When you build an application with such an error, it tells you the reason. Use your editor to build the application and post the output.

Hey Nora,

Welcome to the ranch!

So you're getting an error that says this method doesn't exist right? Let me ask a couple of questions. Is the Node class you create a custom class you or someone else working on the project has built? If so, do you have access to the source code? Does it contain the getmem() method?

Can you post the Node class?

Thank you so much helping me. I've the solution for that!

Incidentally, you're using a C/C++ coding style. In Java, the convention for names is camelCase. So methods are usually named something like getMemId(). Java itself actually doesn't care, but the people and the software tools that work with Java can be confused.

Oh yeah, Thank you so much correcting it.
