Find the error(s) in the following code. This code should append the numbers from 10 down to 1 to outputJTextArea.

Question

```
1 int counter = 10;
2
3 do
4 {
5 outputJTextArea.append( counter + "\n" );
6 }
7 while ( counter > 1 );
8
9 --counter;
```

Answer 1

Line 9 should be placed within the body of the do…while statement between lines 5 and 6. The code above causes an infinite loop—counter is never decremented within the do…while statement, so the loop continuation condition never becomes false. Also, once the decrement statement is moved into the body of the loop, there will be an off-by-one- error. The condition should be either counter >= 1 or counter > 0. The corrected code is dis- played below.
```
1 int counter = 10;
2
3 do
4 {
5 outputJTextArea.append( counter + "\n" );
6 --counter;
7 }
8 while ( counter >= 1 );
```
