2 identically structured beans and 2 identically structured getter statements

[John Piper]

I have two beans that are structured exactly the same. I pull both those beans into the same java class the exact same way. Yet only one of them has a problem.

Here is the error when I try to build it:

cannot find symbol
symbol : constructor BalanceBean(java.lang.String)
location: class HWpackage.BalanceBean

Here is the working bean, UserBean2

package HWpackage;
    
    public class UserBean2 {
      private String id;
    
      public UserBean2(String id) {
        setUsername(id);
      }
    
      public String getUsername() {
        return(id);
      }
    
      public void setUsername(String id) {
        if (!isMissing(id)) {
          this.id = id;
        }
      }
    
      private boolean isMissing(String value) {
        return((value == null) || (value.trim().equals("")));
      }
    }

And here is the working getter statements:

UserBean2 userBean2 = (UserBean2)session.getAttribute("userBean2");
      String un = request.getParameter("id");
      userBean2 = new UserBean2(un);
      session.setAttribute("userBean2", userBean2);

Now compare that to the non-working code.

BalanceBean:

package HWpackage;
    
    public class BalanceBean {
      private String balance, id;
    
      public BalanceBean (String balance, String id) {
        setBalance(balance);
        setID(id);
      }
    
      public String getBalance() {
        return(balance);
      }
    
      public void setBalance(String balance)
      {
          this.balance = balance;
      }
    
      public String getID() {
        return(id);
      }
    
      public void setID(String id)
      {
          this.id = id;
      }
    }

And its getter statements:

    BalanceBean balanceBean = (BalanceBean)session.getAttribute("balanceBean");
    String balance = request.getParameter("balance");
    balanceBean = new BalanceBean(balance);
    session.setAttribute("balanceBean", balanceBean);

For what ever reason "BalanceBean" on line 3 is causing all the problems.

Can someone please tell me why?

You're not looking very close. The error message is telling you exactly what is wrong.

Look at the constructor and look at how you are calling it.

The error is pretty obvious

cannot find a constructor with signature BalanceBean(String)
