int a =(Integer.parseInt(t1.getText()) + Integer.parseInt(t2.getText()));
t3.setText(a);/// error

t3.setText(""+a);//works fine. WHY???

how do you convert int to string

[Tony Morris]

The String concatenation operator is overloaded to take an operand of type int (actually any operand type). The result of the concatenation is always of type String.

Here's the thing, at the end, your setting the text, so no matter what, it's going to be a textual representation. You could do something like this.

Integer i = new Integer(int);
t3.setText(i.toString());

And what is the type of t3? Maybe you should look at the API to see if that object's class takes an int as a formal argument. If it only takes a String then you have already solved your own problem, the actual argument can be "" + i, or use the static method Integer.toString(i).
