我知道这个问题已经被问过很多次了,但我还是不明白为什么我会遇到这个问题。博客和帖子中提供的答案已经在我的代码中实现,我仍然面临这个问题(或者我仍然无法弄清楚我的代码编译失败的原因)
public class Utilities {
public Client client = null;
private static object x = null;
public Utilities(Client client) throws Exception {
this.client = client;
//CODE GOES HERE
}
}
我在其他文件中调用这个类,Utilities utile = new Utilities(client);
当我编译这段代码时,我遇到了错误,
constructor Utilities in class Utilities cannot be applied to given types
required: no arguments
found: Client
reason: actual and formal argument lists differ in length
在浏览了几个论坛帖子和博客之后,我添加了默认承包商,现在我的代码看起来像,
public class Utilities {
public Client client = null;
private static object x = null;
private Utilities() {
super();
// TODO Auto-generated constructor stub
}
public Utilities(Client client) throws Exception {
this.client = client;
//CODE GOES HERE
}
}
但仍然是同样的错误。任何线索我在这里做错了什么。
