为Java中package com.company; import java.util.LinkedList; public class ResultBuffer { final int maxBufferLength = 10; int currentBufferLength = 0; int pointer = -1; LinkedList<String> buffer = new LinkedList<>(); public void addElement(String ele) { buffer.addFirst(ele); if (currentBufferLength < maxBufferLength) { currentBufferLength++; } else { buffer.removeLast(); } } public String getElement() { return buffer.get(pointer); } public void increasePointer() { pointer = (pointer + 1) % currentBufferLength; } public void resetPointer() { pointer = 0; } }每一行添加注释
