I am getting error during following code

Java

String str=jTable1.getModel().toString();
jTable2.setModel(str);

I want to store table model to access database in string format and retrieve this data from database in string format and assign it to table.

How I can convert this?

You are totally lost in the very beginning. You need to unlearn what you have learned so far and start from the very beginning. I am serious.

Why, why using the string at all? This is the biggest flaw and misconception of many present-day beginners: thinking that all objects are string. You need to work with objects themselves, not strings representing those objects. In your case, the string obtained from the model via toString() does not even represent the model.

I already explained it for your. Your follow-up question is yet another confirmation that you have to start learning programming from the very beginning, otherwise nothing could help you.

Thank you sir for giving me your valuable time.
Actually I am beginners in java so i am trying some experiments of use of all methods of all important component like jTable,jList etc.
I check your profile and you are very genius in programming.
I know practice make perfect and in programming field we need lot of experiments to remember actual concept and i agree with you that i can not use String to setModel() method of jTable because it is volatile the rule of forcefully type casting of java

Thank you sir.

I guess, jTable2.setModel(jTable1.getModel()) would do, if this what you want.
If it makes sense for you, will you accept the answer formally (green "Accept" button)? In all cases, your follow-up questions will be welcome.
