Output problem with write() function.

Question

Hi there
This program produced the output only when i add "System.out.write('\n')",
WHY?
import java.io.*;
class WriteBytes
public static void main(String[] args) throws IOException
byte[] b = {'T','e','s','t'};
for(int i = 0; i < b.length; i++)
System.out.write(b);
System.out.write('\n'); // Why if i comment this line then, don't get the output.

Answer 1

Your program is finishing before the buffer has a chance to flush. The newline character is forcing a flush to the print output. You could use System.out.println() to force the newline or System.out.flush() would work as well.
