编译错误“实际参数和形式参数列表的长度不同”

Question

在编译“ AccountTest.java”时出现以下错误...如何解决相同的问题。请帮助我。

AccountTest.java:7: error: constructor BankAccount in class BankAccount cannot be applied to given types;
BankAccount obj = new BankAccount("Clark", 123);
                  ^
  required: no arguments
  found: String,int
  reason: actual and formal argument lists differ in length

BankAccount.java

package AccountPack;

public class BankAccount
{
String CustName;
int AcNumber;

public void BankAccount(String n, int a)
{
CustName = n;
AcNumber = a;
}

public void display()
{
System.out.println("Name: " +CustName);
System.out.println("Account NUmber: " +AcNumber);
}
}    

AccountTest.java

import AccountPack.BankAccount;

class AccountTest
{
public static void main (String args[])
{
BankAccount obj = new BankAccount("Clark", 123);
obj.display();
}
}

Answer 1

您的ontructor应该会这样。

 BankAccount(String n, int a)
{
CustName = n;
AcNumber = a;
}
