Java“类中的构造函数不能应用于给定类型"“必需:找不到参数:字符串" [英] Java 'constructor in class cannot be applied to given types' 'required: no arguments found: String'

问题描述

我正在处理一项作业，我必须从头开始创建一个链表，并且在编译时遇到一个错误:Node 类中的构造函数 Node 无法应用于给定类型；"

I'm working on an assignment where I have to create a linked list from scratch and have come across an error when compiling that the "constructor Node in class Node cannot be applied to given types;"

这就是我正在尝试的，错误说:

This is what I'm trying, the error says:

必需:无参数找到:字符串

required: no arguments found: string

但是我看不出哪里出错了，因为我的 Node 构造函数需要一个字符串?

Yet I cannot see where I am going wrong as my constructor for Node requires a string?

public class Node {
    String data;
    Node next;

    public void Node(String x) {
        data = x;
        next = null;
    }
}



public class stringList {
    private Node head;
    private int count;

    public void stringList() {
        head = null;
        count = null;
    }

    public void add(String x) {
        Node temp = new Node(x);
    }

这是编译器显示的错误截图

推荐答案

这个:

public void Node(String x) {
    data = x;
    next = null;
}

应该是:

   public Node(String x) {
        data = x;
        next = null;
    }

目前您有一个 default 构造函数(不带参数)，它是在没有任何显式构造函数的情况下隐式定义的.

Currently you have a default constructor (taking no arguments), which is implicitly defined in the absence of any explicit constructors.
