Listen Klasse Implementieren

anlinn

The List class contains an integer "info" field and a next field. The List class also has two constructors: one that takes two int values (x,l), and another that takes one int value (x). The List class also has two methods: one that inserts an element at position x in the list, and another that deletes the element at position x from the list. The toString() method returns a string that shows the list's contents, starting with the info field and continuing for each element in the list, separated by a comma. The List class also has a public instance variable next that points to the next list in the list's linked list.

public class List{
  public int info;
  public List next;
  
  //Konstruktoren:
  public List (int x, List l){
    info = x;
    next=l;
  }
  
  public List (int x){
    info = x;
    next =null; 
  
  // Objekt- Methoden
    public void insert(int x){
    next = new List(x,next);
    }
  
    public void delete(){
      if (next != null)
        next = next.next;
    
    }
    
    public String toString(){
      String result = "["+info;
      for(List t = next; t!=null; t=t.next)
        result = result +", "+ t.info;
      return result +"]";
    }
    
    
    
    
    
    
  }
