Java Exercise

[Dave128]

Hi, I have an exercise I need to do for Java. I am not sure how to start this program. Can somebody help me get started on this problem? Thanks in advance for your help. The problem is as follows:
Develop a Java application that will determine whether any of several department-store customers has exceeded the credit limit on a charge account. For each customer, the following facts are available:
a) account number
b) balance at the beginning of the month
c) total of all items charged by the customer this month.
d) total of all credits applied to the customer's account this month.
e) allowed credit limit.

The program should input all these facts as integers, calculate the new balance(= beginning balance + charges - credits), display the new balance and determine whether the new balance exceeds the customer's credit limit. For those customers whose credit limit is exceeded, the program should display the message "Credit limit exceeded"

Start by working on how to get the input and store in conveniently.

Here is code I started but I am getting errors. Can anybody help me get this problem corrected?

[/code]
import java.util.Scann er;

public class CreditCheck
{
Scanner input = new Scanner( System.in );
// define instance variable
int acctNo = 0;
double shopinitA = 0.0;// initial balance
double shopcharges = 0.0; // charges applied to user's acct
double shopcredits = 0.0; // credits applied to user's acct
double shopcreditlimit = 0.0; // user's acct limit
double newbal = 0.0; //user's calculated balance
double positivecredit = 0.0; // money left to spend
double negativecredit = 0.0; // amount of money overdrawn
String msg = "";

public CreditCheck()
{
}

//acct number based on user's input
public void setAccountNumbe r (int acctNo)
{
acctNo = acctNo;
}

//method for initial balance on user's input
public void setInitialBalan ce (double initA)
{

}

// method to establish total charges based on user's input

}

//method establishes total credit based on user's input
public void setCreditLimit (double creditLimit)
{
shopcreditlimit = creditLimit;
}


// balance calculation and results
public void showResult()
{
//calculate balance
newbal = (shopinitA + shopcharges)- shopcredits;
positivecredit = shopcreditlimit - newbal;
negativecredit = shopcreditlimit - (newbal);



//user balance options
if ( newbal < 0 )
System.out.prin t( "Your balance is $" , newbal(positive credit) +"to spend.");

else if ( positivecredit >=0 )
System.out.prin t( "Your balance is $" , newbal + "\n and you still have $");

else
System.out.prin tln ("Credit Limit exceeded" );
}

}

The errors were caused by the incorrect print statements. I suppose you are going to write the main method for testing the logic of your solution?
