+
+  
+  <div>
+    <p>在写代码的时候，从头至尾都应该考虑性能问题。这不是说时间都应该浪费在优化代码上，而是我们时刻应该提醒自己要注意代码的效率。比如：如果没有时间来实现一个高效的算法，那么我们应该在文档中记录下来，以便在以后有空的时候再来实现她。 不是所有的人都同意在写代码的时候应该优化性能这个观点的，他们认为性能优化的问题应该在项目的后期再去考虑，也就是在程序的轮廓已经实现了以后。 </p>
+
+    <p>不要在循环中构造和释放对象。</p>
+
+    <p>使用 StringBuffer 对象。在处理 String 的时候要尽量使用 StringBuffer 类，StringBuffer 类是构成 String 类的基础。String 类将 StringBuffer 类封装了起来，（以花费更多时间为代价）为开发人员提供了一个安全的接口。当我们在构造字符串的时候，我们应该用 StringBuffer 来实现大部分的工作，当工作完成后将 StringBuffer 对象再转换为需要的 String 对象。比如：如果有一个字符串必须不断地在其后添加许多字符来完成构造，那么我们应该使用 StringBuffer 对象和她的 append() 方法。如果我们用 String 对象代替 StringBuffer 对象的话，会花费许多不必要的创建和释放对象的 CPU 时间。 </p>
+
+    <p>避免不必要的使用关键字 synchronized，应该在必要的时候再使用她，这是一个避免死锁的好方法。</p>
