java我试图将今天的日期添加到我的对象，但构造函数有问题

Question

我是Java新手，对构造函数有一些问题

下面是错误：“构造函数事务（Type\u Transaction、String、Particulier、Agent\u immobilier）未定义”

我要做的是创建具有今天日期属性（格式字符串）的对象。所以在我的构造函数中，我不想把一个参数设置为“date”。我还在字符串中转换今天的日期

public class Transaction {

private String date_transaction;
private Particulier leparticulier;
private Agent_immobilier lagent;
private Type_Transaction type_transaction;
private DateFormat dateFormat = new SimpleDateFormat("dd/MM/yyyy");



private Transaction(Type_Transaction type_transaction, Particulier leparticulier, Agent_immobilier lagent) {
    super();
    this.type_transaction=type_transaction;
    this.leparticulier=leparticulier;
    this.lagent=lagent;
    this.date_transaction = Date_Ajd();
}

public String Date_Ajd(){
    Date date=new Date();   
    String date_ajd = dateFormat.format(date);
    return date_ajd;

}

public static void main(String[] args) {
    Particulier Alfred=new Particulier(xxxx);
    Agent_immobilier Lilian=new Agent_immobilier(xxxxx);
    Transaction number1 = new    Transaction(Type_Transaction.Location,Alfred,Lilian);
}

根据您的错误，您需要向构造函数添加一个字符串参数，如下所示：

private Transaction(Type_Transaction type_transaction, String theString, Particulier leparticulier, Agent_immobilier lagent) {

您的代码实际上不会抛出错误
