为了优化Java的性能 ,JVM在解释器之外引入了即时(Just In Time)编译器:当程序运行时,解释器首先发挥作用,代码可以直接执行。随着时间推移,即时编译器逐渐发挥作用,把越来越多的代码编译优化成本地代码,来获取更高的执行效率。解释器这时可以作为编译运行的降级手段,在一些不可靠的编译优化出现问题时,再切换回解释执行,...

其中,RuntimeException 不应该通过 catch 语句去捕捉,而应该使用编码手段进行规避。 13.合理使用 PreparedStatement PreparedStatement 使用预编译对 SQL 的执行进行提速,大多数数据库都会努力对这些能够复用的查询语句进行预编译优化,并能够将这些编译结果缓存起来。
TimeUnit是java.util.concurrent包下面的一个类,TimeUnit提供了可读性更好的线程暂停操作,通常用来替换Thread.sleep(),在很长一段时间里Thread的sleep()方法作为暂停线程的标准方式,几乎所有Java程序员都熟悉它,事实上sleep方法本身也很常用而且出现在很多面试中。如果你已经使用过Thread.sleep(),当然我确信你这样做过...
