Java节点LinkedList

Question

Java Nodes/ LinkedList(Pointer based) the program is basically a node that includes student attributes:

first name last name age ID Major

There are 3 classes : 1- nodeclass 2- class for the methods (add in the beginning, and add in the end, search etc.. 3 -the test class

the problem that I'm facing is that I am confused on how to include all the students attributes into one node.

Now an example of the node class(1) to add an integer is:

public class IntNodeF14
{
  int item; 
  IntNodeF14 next;
}

how can I create a node that will accept all the students attributes

Answer 1

Make your class generic :

public class NodeF14<T>
{
  NodeF14<T> next;
  T data;
}

data would hold the data of a single node.

Then you can create a NodeF14 for any type of data you need.

For example :

Student student = new Student (firstName,lastName);
NodeF14<Student> studentNode = new NodeF14<Student> (student);

If you can't use generics, you'll have to include all the properties (or a Student member holding all the properties) in the Node class, but in this case your list will only support one type of data.
