How to Flush a Buffered Reader in Java
The "PrintWriter" statement flushes the buffered reader in the Java language. Java has a buffer that contains the information you want to output to the user. It continues to fill up and store the information in the computer' memory. When you use the "PrintWriter" command in Java, the buffer flushes and the memory releases the information stored.
