 Customers[] custTxt = new Customers[30];
 
custTxt[index]=new Account1(accID,name.toUpperCase(),address,dob,phone,accBal,accType);

when i do a custTxt[i].get_accType();

it show an error;

java:212: cannot find symbol
symbol  : method get_accType()
location: class Customers
                    smallBuff.write("Account type: "+custTxt[i].get_accType());

need help on how to show this error...

sorry to post this question here...

Main class codes frag

public static void main(String[] args) 
    {
 
			double new_interest=0.0;
 
			BankDB custData = new BankDB();
			Scanner input = new Scanner (System.in);
			int accID=0;
			int index=0;
  			String fileName="";
  			char userInput='0';
  			while (true)
  			{
  				System.out.println("First Bank Customer Query System..");
  				System.out.println("==================================");
  				System.out.println("(1)	Input Data from text file");
  				System.out.println("(2)	Print out Customer Info onto console");
  				System.out.println("(3)	Write Customer Info to a text file");
  				System.out.println("(4)	Delete data");
  				System.out.println("(5) Update account");
  				System.out.println("(Q)	Quit the system");
  				System.out.println("Your choice:");
  				userInput=input.next().charAt(0);
  				try
  				{
  				switch(userInput)
  				{
  					case '1':
  						String[] tempNames=new String [30];
 
  						System.out.println("Please enter filename:");
						fileName= input.next();
						custTemp=custData.readFile(fileName);
						for(int i=0; i<custTemp.length;i++)
						{
							tempNames[i]=custTemp[i].get_name();
 
						}
						Arrays.sort(tempNames);
						custTxt.clear();
						for(int j=0;j<tempNames.length;j++)
						{
							for (int i=0; i<custTemp.length;i++)
							{
								if(tempNames[j].equalsIgnoreCase(custTemp[i].get_name()))
								{
									custTxt.add(j,custTemp[i]);
								}
							}	
						}
 
 
						break;

what these codes is supposed to do is get some data from a text file and put them into an user define type array, sort them into alphabetical order and lastly insert them into an ArrayList...

my logic error faced is that when i do

System.out.println(custTxt.get(1).print());

the contain is empty.. but if i do this instead:

System.out.println(custTemp[1].print());

there are values printed out.. need help on how to solve this...

thx
