Writes count or one byte to target stream/buffer.

===== Language Example =====
<code java>

FileWriter stream = new FileWriter("output.txt"); // create file
BufferedWriter output = new BufferedWriter(stream);
) {
output.write("Hello Harddisk"); // Write to Stream
//This is an auto-closable block so no need of "output.close();"

obably the first method learned in Java was the ''System.out.println()'' method. Well, this can be applied... // for better visualization of error
System.out.println(e.getMessage());
