Do I have to close FileOutputStream which is wrapped by PrintStream?

Question

I\'m using FileOutputStream with PrintStream like this:

class PrintStreamDemo {  
    public static void main(String args[]) { 
            


        

Answer 1

No , here is implementation of PrintStream's close() method:

public void close() {
    synchronized (this) {
        if (! closing) {
        closing = true;
        try {
            textOut.close();
            out.close();
        }
        catch (IOException x) {
            trouble = true;
        }
        textOut = null;
        charOut = null;
        out = null;
        }
    }

You can see out.close(); which closes output stream.
