No, you cannot directly set an int value to a text area's text in Java. Text areas are designed to display strings, so you need to convert the int value to a string before setting it as the text of the text area.

You can do this by using the String.valueOf() method or by concatenating an empty string with the int value. Here's an example:

int intValue = 10;
textArea.setText(String.valueOf(intValue));

Alternatively, you can use concatenation:

int intValue = 10;
textArea.setText("" + intValue);

Either of these methods will convert the int value to a string and set it as the text of the text area without any errors.

So if the int value is for example 10 would it make the text "ten" if i do that?

[shy briar]

no 10 wil come out as 10, if u want ten , that's another story

[vital coyote]

oh, ok thank you!

i just started java alone without any help this friday

so i might not be that well at it-

[vital coyote]

i have another fast question

im making a calculator so for example when i click 1 two times it makes 11

how to do that

[shy briar]

by not looking at it like a number. Its text, then converted when u need actaual math

[vital coyote]

???

[vital coyote]

i still dont know how to do that

So strings(text) and integers(numbers) are different and work different

Numbers work as you'd expect.

So 10 + 10 gives 20
But "10" + "10" gives "1010" cause strings have no concept math

valueOf functions can help convert between the two

The plus operator for strings is a bit misleading as when a string is involved it doesn't do math whatsoever

[unkempt reef]

concat the values as strings, as fa mentioned

would be the easiest way. otherwise, if you're feeling adventurous, you could use some math to manage the place value

right before you add the next digit, multiply the current value by 10 to move it over one place value
