Hello,
Try the following code, this may help you

Code:

Public class account
{
private float bal;
private static float numcp =0;
/ / numcp is initialized to zero, it is common to all classes and for each instantiation it will change in value since it is incremented.
 
Public account()
{numcp + +;}
/ / The first account will be number 1
/ / default bal will be initialized to zero.
 
Public void credit(float amount)
{bal + = amount;}
 
Public void charge(float amount)
{bal-= amount;}
 
Public float getSolde()
{return(bal);}
/ / accessor method for reading 
 
Public void display()
{System.out.System.out.println("account number"+ + numcp"The bal is"+ bal +"Dinars");}}

Public class TestBanque
{Public static void hand (String [] args)
	{Account acc =new account();
/ / Instance 1 will account number 1 and a bal of 0.
	acc.credit(1000);
acc.dbitrate(500);
acc.display();
              account = acc2 new account();
/ / instance 2 will have the account number 2 and a bal of 0.

acc2.credit(5000);
acc2.dbitrate(250);
acc2.display();
	}
}

Hello,
I do not understand your use of the static attribute comprises. Each account to account number 1 (as a primary key in a table) each instance of the class Account is a complete. If I instantiate the class twice, I find myself with two accounts with different balances and account number the same? I hope you are doing the correct things in your code. Best of Luck

Hello,
I think you are doing something wrong here , that is this part of the program

Code:

private static float nmcmp =0;
/ / nmcmp is initialized to zero, it is common to all classes and for each instantiation it will change in value since it is incremented.
 
Public account()
{nmcmp + +;}

I think you will need a alternative for this part of the code, I have no idea right now but when I will have one I will let you know about it.

Hello,
Even I think that something is missing in the code
For example
Account 1: pay 15 d
Account 2: pay 25 d
Suppose I call my method display () the first object is not connects the program back to it.

Code:

Account number two The balance is 15 d

I think the logic is somewhere wrong in the problem. I have not found a replacement yet, but I will try to find one. Still, then you work on it.

Hello,
That was just to have it in future responses more quickly is not easy to get an immediate answer on some work that has been started, but good for this example is easy
To answer your question is, the display will be:

Code:

Account number 1 The balance is 450 d.
the Account number 2 The balance is 4645 d.

This is initialized to 0 and at each instantiation it will be incremented, so the object 1 will be the number 1, it also uses this method to determine the number of instantiation has been done.
