请帮我为以下代码添加注释，并排版package T14; //Buffer.java public class Buffer { private int buffer = -1; // buffer缓冲区被producer 和 consumer 线程共享 private int occupiedBufferCount = 0; // 控制缓冲区buffers读写的条件边量 public synchronized void set( int value ) //place value into buffer { String name = Thread.currentThread().getName();//get name of thread that called this method // while there are no empty locations, place thread in waiting state while ( occupiedBufferCount == 1 ) { // output thread information and buffer information, then wait try { //System.err.println("Buffer full. "+ name + " waits." ); wait(); } // if waiting thread interrupted, print stack trace catch ( InterruptedException exception ) { exception.printStackTrace(); } } // end while buffer = value; // set new buffer value ++occupiedBufferCount; System.err.println(name + " writes " + buffer); notify(); // tell waiting thread to enter ready state } // end method set; releases lock on SynchronizedBuffer public synchronized int get() // return value from buffer { // for output purposes, get name of thread that called this method String name = Thread.currentThread().getName(); // while no data to read, place thread in waiting state while ( occupiedBufferCount == 0 ) { // output thread information and buffer information, then wait try { //System.err.println("Buffer empty.

// 该代码实现了一个Buffer类，用于控制producer和consumer线程对缓冲区的读写
package T14;

// 当没有空位置时，将线程置于等待状态
while (occupiedBufferCount == 1) {
try {
//System.err.println("Buffer full. "+ name + " waits." );
wait();
} catch (InterruptedException exception) {

// 设置新的缓冲区值
