}

my code was this. I tried to compile this, but that error got happened.

Could you please tell me how to handle this error?

That does not look like an error.

In IDE 2.x, you should get a popup if there is an error, in IDE 1.x the bar above the output pane will turn orange/red and will have a button "Copy error messages".

Please show a error message in full

What you posted isn't an error message but an info about memory usage - even if it is printed in red.
