You need something to keep track of how many Transactions have occured. Maybe a transID field. So something along the lines of..

Code:
int transID = 10001;
public void New(){

text.setText(item[0]+"\n"+item[1]);
text1[0].setText("");
text1[2].setText("");
text1[4].setText("");
text1[6].setText("");
text1[8].setText("T"+transID.toString());<----- this is the one...
transID++;
}
Everytime you call that method transID will be added to.. Not sure if that is correct code, not sure what you are using. But it should give you and idea on how to do it.

Wow...what language is this?

I think it would be better if you posted what you're actually trying to accomplish. I suspect you're trying to do something easy the hard way.

Anyway, along the lines of what somebody else said...if you're looking for a way to get unique, sequential integers, you should probably build a separate class to hold that stuff. Keep a private, static integer id in the class and provide a method to fetch the next id. This method will increment the private variable and then return the new value.

Edit: Also, if this is java, then naming a method "New" is a really bad idea.
