可能是的.如果新对象的构建很昂贵(例如建立数据库连接)，或者由于其他原因GC带宽太高(在Android领域通常会出现问题)，则可以在许多情况下看到性能提高.

It is possible yes. You can see performance improvements in many situations if the construction of a new object is expensive (like establishing a database connection) or if for other reasons the GC bandwidth is too high (often a problem in Android-land).

以下是一些可用于实现池的资源.您也许可以立即使用Apache的ObjectPool.

Here are some resources that you could use to implement your pool. You may be able to use Apache's ObjectPool right out of the box.

• Apache Commons ObjectPool
• 此基本Java对象池是否起作用?
• 在Java中构建自己的ObjectPool以提高应用速度
• Java中的对象池设计模式
• Google搜索:java对象池
