NULL is used in computing most often (always?) to signify "not a value." This is different than zero: in a bank database, a zero value means no money, while a NULL value means there has been no value assigned to the balance.

This is a specialized usage, but increasingly common as more people learn to program.

You have a couple problems. I solved the first one, but it will relate to the second and third. The first issue is how you create you accounts. Your current constructor is:

    public bankAcct(int pacctNum, double pBal, String pname) 
{
    pBal = Bal;
    pacctNum = acctNum;
    pname = name;
} 

It should be this:

        public bankAcct(int pacctNum, double pBal, String pname) 
    {
        Bal = pBal;
        acctNum = pacctNum;
        name = pname;
    } 

Here you had the values reversed, which prevented you from assigning an account number, last name, and balance to the account you created.

Secondly, your findAcct and seeBalance methods should look like this:

    public bankAcct findAcct()
{
    bankAcct myBankAcct = null;
    System.out.println("Greetings, please enter your account number: ");
    int acctNum = scannerObject.nextInt();
    //make sure you use myAcct.length to ensure you don't get an "ArrayOutOfBoundsIndex" error.
    for(count = 0; count < myAcct.length; count++){
        myBankAcct = myAcct[count];
        if(myBankAcct.getAcctNum() == acctNum){
            return myBankAcct;
        }
    }
    return myBankAcct;
 }

public void seeBal()
{
    bankAcct lfound = findAcct();
    if (lfound == null)
    {
        System.out.println("Error!");
    }else{
        lfound.dispBal();
    }
}

Your biggest problem was with your findAcct method. You never found the account. This is what you did:

    public int findAcct()
{
    int lnum = -1;
    System.out.println("Greetings, please enter your account number: ");
    //you get the users acct #
    lnum = scannerObject.nextInt();
    for(count = 0; count < max; count++){ //here you iterate, but you never "find" the account
        if (count == lnum)
            return count; //then you return the "count" rather than the account itself.
            }
    return lnum;
    }

If you make the changes I made, it will run through choice 2, but there are going to be some errors that you are going to have to deal with. If you take the lesson from this post, you should be able to address the other issues you have in your program. You should be able to make your Deposit and Withdraw methods look like the seeBalance method.

Here is the output from what I ran
