Question

public void decompressTo(String fileName) throws IOException {

    for (int i = 0; i < fileArray.size(); i++) {
        if (fileArray.get(i) == new Character((char) 7)) {
            //do stuff
    }
    else {
        //do other stuff
    }
}

The problem is that my if statement is never being executed, instead, the for loop always jumps to the else statement.

However, the fileArray ArrayList that I am reading from for sure contains the bell character (ASCII Character #7). I have declared fileArray as follows: ArrayList <Character> fileArray = new ArrayList <Character> ();.

Answer 1

Creating new Character((char) 7)) seems unnecessary object creation. Hence

Try this. Make suere your fileArray.get(i) is not null.

if (fileArray.get(i).charValue() == '7')
