class Cell<e>{

private Cell<e> next;

Cell(e ele){
  this.element=ele;
}

Cell(e l,Cell<e> k){
  Cell<e>(l);
  this.next=k;
}

public Cell<e> getnext(){
  return next;  
}

public e getelement(){
  return element;
}
}

public class test{
public static void main(String[] args){
Cell<int> l=new Cell<int>(123);
Cell<String> ele=new Cell<String>("awdadw",l);
System.out.println(ele.getelement());
System.out.println(ele.getnext().getelement());
}
}
大家帮忙看一下并改正，谢谢

下面截图演示：

class Cell<e>{
private e element;
private Cell<e> next; //next私有

Cell(e ele){
  this.element=ele;
}

Cell(e l,Cell<e> k){
    Cell(l);        //构造函数只能new时，才能调用改为  this.element=l;
  this.next=k;
}


public Cell<e> getnext(){
  return next;  
}

public e getelement(){
  return element;
}
}

public class test{
public static void main(String[] args){
Cell<Integer> l=new Cell<int>(123);//泛型中定义类型，必须是引用类型，int不是基本类型不属于引用类型。可改为Cell<Integer> l =new Cell<Integer>(123);
Cell<String> ele=new Cell<String>("awdadw",l);//泛型类一旦声明类型，那么定义固定，可以修改成 Cell<String> ele=new Cell<String>("awdadw",new Cell<String>("123"));
System.out.println(ele.getelement());
System.out.println(ele.getnext().getelement());
}
}
