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);
				}

		}

That's not all the files but the rest are just for the radio buttons and stuff.

Post absent classes.

...Check.java:21: cannot find symbol

    super(tId, tAmt, tCount);

symbol: constructor Transaction(int,double,int)
location: class Transaction
where

 public Check(int tId, double tAmt, int tCount, int checkNumber) {
 public Transaction(int num, int id, double amt) {

Edited 3 Years Ago by Reverend Jim: Fixed formatting

Problem solved.

For the printf function, I had recently learned that I must put everything into a String variable first then format it in the String variable itself.

For the inheritance thing, I found out that Check can be inserted into the Transaction array even if it was pre-declared that the array can only contain Transaction objects. This was because Check is derived from Transaction so technically "Check is a Transaction."

If anyone has the same problem as me, I hope that this will help when they search the forum.
