Java 7 introduced the multi-catch feature, allowing you to handle multiple exception types in a single catch block. This can lead to more concise and readable code, especially when you want to handle different exceptions in the same way. Here's a simple example: try{// code that may throw...
So far we have seen how to use a single catch block, now we will see how to use more than one catch blocks in a single try block. In java, when we handle more than one exceptions within a single try {} block then we can use multiple catch blocks to handle many different kind of...

As you can see that inrethrowmethod, catch block is catching Exception but it’s not part of throws clause. Java 7 compiler analyze the complete try block to check what types of exceptions are thrown and then rethrown from the catch block. Note that this analysis is disabled if you change...
public void rethrowException(String exceptionName) throwsFirstException, SecondException{ try { // ... } catch (Exception e) { throw e; } } This analysis is disabled if thecatchparameter is assigned to another value in thecatchblock. However, if the catch parameter is assigned to another va...
Since version 7, Java has supportedcatching multiple exceptionsin onecatchblock, for example: // Java code try { // ... } catch (Exception1 | Excpetion2 ex) { // Perform some common operations with ex } However,Kotlin hasn’t supported this feature until the current version (1.7.0)....

为了保证线程最终都能释放锁,你可以把Monitor.Exit()方法写在try-catch-finally结构中的finally代码块里。对于任何一个被Monitor锁定的对象,内存中都保存着与它相关的一些信息,其一是现在持有锁的线程的引用,其二是一个预备队列,队列中保存了已经准备好获取锁的线程,其三是一个等待队列,队列中保存着当前正在等待这个...
