Just one addition you may not get from the tutorial: when adding/removing components to/from an already visible/realized GUI, be sure to call revalidate() and repaint() on the enclosing container. Or, in the scenario you describe, you may want to call pack() on the top level window instead.




Thanks.. I tried your ideas.. Got it .. but faced challenge in Validation with Text Field and Combo box

Hard to get the the reference for single component
Because all components are generated dynamically
Please help me..

Please share your ideas

One Button will be available in Top . When clicking the button it should create the JTextfield,JLabel,Jcombobox
It should satisfy the Grid bag constraints
Object of components will be created dynamically

When sending large amounts of data to a class, it should be done in a structured way. What is in the array that you are going to send?



(HeaderString,Timestamp,String,String)

Three values for specific HeaderString value, it will be send using ProcessInfo and Worker class

Destination class will have Header string value and search in Incoming Parameter value via Resultset

Hi am new to Ranch||

Am looking to carry the large amount of data as Whereclause to another using ProcessInfo class

In Another class, ill have the invoiceID , search the 3 consecutive values in the Whereclause.

(String InvoiceID,Timestamp DateInvoice,String Prefix,String Physical)

such one string value contains 22 characters and totally (22*3 )*1000= 66,000 String and 1000 Timestamp values

Which is the performance between ?

Which datatype is better?

1. ArrayList
2. StringBuffer
3. HashMap
4. Any other specify the datatype ?

Hi all,

i am supposed to send the specific huge data to another class as parameter.
That Input Parameter in second class is necessary to make iterate in Resultset to get specific data.

can i send the parameter as StringBuffer or Array list.

When i send as StringBuffer It might be blocks of strings like

((a,b,c) in ((1,...),(...),(...),............(n,...)) if it is large data means it might be like long and takes more time to search any data.

When i send as stringbuffer, i have to split the string buffer using StringTokenizer .
But it got failed due to usage of special characters(comma,=)

which is best for handling huge amount of data.........
