return 1; } finally { return 2; } When the Try block executes its return, the finally block is entered with the reason of returning the value 1. However, inside the finally block the value 2 is returned, so the initial intention is forgotten. In fact, if any of the other code in t...

java在finally里面执行save方法没生效 java中finally的作用 最近在读Thinking In Java,秉着有些地方还能知道自己不会的精神,都去好好查阅了一些资料,在内存分配这一章,看到finalize()这个方法,刚开始很不理解,查阅了一些资料,顺带看了一下final、finally,现在分享一下。 一、final的介绍 final可用在4个地方,分别是...
Java 语言规范第四版(《The Java™ ProgrammingLanguage, Fourth Edition》)中对于 try,catch,和 finally 的描述。 *** 12.4. Try, catch, and finally You catch exceptions by enclosing code in Try blocks. The basic syntax for a Try block is: { statements } catch (exception_type1 identifier...

java的finally一定会执行吗 java中finally一定会执行吗 个人总结: 1.finally是否一定执行? a) 只有与 finally 相对应的 try 语句块得到执行的情况下,finally 语句块才会执行。若在执行try之前 return 或者抛出异常,则try不会执行,try块的finally自然不会执行。
try {// some code that may throw an exception} catch (Exception e) {// handle the exception} finally {// code in this block will always be executed// e.g., close resources, cleanup, etc.} finalize: finalize是一个方法,属于Object类中的一个方法。它在对象被垃圾回收之前被调用,允许对象在...
In the world of Java programming, precision in terminology is crucial, especially when it comes to the trio of "final," "finally," and "finalize." These concepts, although sharing linguistic similarities, serve distinct roles in Java code. Understanding their nuances is paramount for Java develop...
