Another day yet another assignment, which is why I am here. I come with 2 problems.
1. I cannot for the life of me figure out the printf function.
I want to do be able to do this:
Number Type Amount
1 type 2.00
2 type 12.00
Well right now, my program is doing this because I am only using println.
Number Type Amount
1 type 2.00
2 type 12.00
If I try to use printf, a lot of errors in green are popping out, i mean a lot.
2. I am currently working on a bank program and has a Transaction object array, which contains stuff for a bank transaction but suddenly I was asked to use Inheritance, so now, that Transaction class is now a parent class to Check. If the transaction is a check ( meaning the customer is going to cash a check ), I must use the Check class and not the Transaction. My problem is, how can I use the derived Check class if necessary without disrupting my Transaction object array? Codes attached.
Any input would be really appreciated.
Check class:
public class Check extends Transaction
{
private int checkNumber;
public Check(int tId, double tAmt, int tCount, int checkNumber)
{
super(tId, tAmt, tCount);
this.checkNumber = checkNumber;
}
public int getCheckNumber()
{
return checkNumber;
}
public void setCheckNumber(int checkNumber)
{
this.checkNumber = checkNumber;
}
}Transaction class:
public class Transaction
{
int transNumber;
int transId;
double transAmt;
public Transaction(int num, int id, double amt)
{
transNumber = num;
transId = id;
transAmt = amt;
}
}CheckingAccount:
import java.text.DecimalFormat;
public class CheckingAccount extends Account
{
private Transaction[] arrayOfTransactions;
private int transCount;
private double balance;
private double totalServiceCharge;
DecimalFormat a = new DecimalFormat("###,###.00");
public CheckingAccount(String name,double initialBalance)
{
super(name,initialBalance);
balance = initialBalance;
arrayOfTransactions = new Transaction[100];
transCount = 0;
}
public double getBalance()
{
return balance;
}
public void setBalance(double transAmt, int tCode)
{
if(tCode == 1)
{
balance = Main.processCheck(transAmt);
}
else if(tCode == 2)
{
balance = Main.processDeposit(transAmt);
}
}
public double getServiceCharge()
{
return totalServiceCharge;
}
public void setServiceCharge(double currentServiceCharge)
{
totalServiceCharge = totalServiceCharge + currentServiceCharge;
}
public int getTrans()
{
return transCount;
}
private void increaseSize()
{
Transaction[] temp = new Transaction[arrayOfTransactions.length * 2];
for (int cd = 0; cd < arrayOfTransactions.length; cd++)
{
temp[cd] = arrayOfTransactions[cd];
}
arrayOfTransactions = temp;
}
public void addTrans(int tempNum, int tempId, double tempAmt)
{
if (transCount == arrayOfTransactions.length)
{
increaseSize();
}
arrayOfTransactions[transCount] = new Transaction (tempNum,tempId,tempAmt);
transCount++;
}
public void printAll()
{
System.out.println("Transaction list for");
System.out.println("Name: " + getName());
System.out.println("ID" + " " + "Type" + " " + "Amount");
for( int i = 0 ; i < transCount ; i++ )
{
if(arrayOfTransactions[i].transId == 1 )
{
System.out.println(arrayOfTransactions[i].transNumber + " " + "check" + " " + arrayOfTransactions[i].transAmt);
}
if(arrayOfTransactions[i].transId == 2 )
{
System.out.println(arrayOfTransactions[i].transNumber + " " + "deposit" + " " + arrayOfTransactions[i].transAmt);
}
if(arrayOfTransactions[i].transId == 3 )
{
System.out.println(arrayOfTransactions[i].transNumber + " " + "svc.chrg." + " " + arrayOfTransactions[i].transAmt);
}
}
}
public void printChecks()
{
System.out.println("Checks cashed:");
System.out.println("ID" + " " + "Amount");
for( int i = 0 ; i < transCount ; i++ )
{
if(arrayOfTransactions[i].transId == 1)
{
System.out.println(arrayOfTransactions[i].transNumber + " " + arrayOfTransactions[i].transAmt);
}
}
}
public void printDeposits()
{
System.out.println("Deposits made:");
System.out.println("ID" + " " + "Amount");
for( int i = 0 ; i < transCount ; i++ )
{
if(arrayOfTransactions[i].transId == 2)
{
System.out.println(arrayOfTransactions[i].transNumber + " " + arrayOfTransactions[i].transAmt);
}
}
}
