NullPointerException is a runtime exception, so we don’t need to catch it in the program. NullPointerException is raised in an application when we are trying to do some operation onnullwhere an object is required. Some of the common reasons for NullPointerException in java programs are: I...
checked exception(检查异常,编译异常),也称非运行时异常(运行时异常以外的异常就是非运行时异常),java编译器强制程序员必须进行捕获处理,比如常见的IOExeption和SQLException。对于非运行时异常如果不进行捕获或者抛出声明处理,编译都不会通过。 Throwable: 有两个重要的子类:Exception(异常)和 Error(错误),二者都是 Ja...

Thejava.lang.RuntimeException: Map operator initialization failedexception occurs when there is an error during the initialization of a map operator. By understanding the exception, handling it appropriately, and preventing it from occurring, we can write more robust and error-free Java programs. ...
在Java中,当你需要统一处理异常的时候,你是会选择catch (Exception),还是直接catch (Throwable)? Java的异常体系 Throwable: Java中所有异常和错误类的父类。只有这个类的实例(或者子类的实例)可以被虚拟机抛出或者被java的throw关键字抛出。同样,只有其或其子类可以出现在catch子句里面。

Most people always have the following problem when run their java programs under linux box: Exception in thread "main" java.lang.NoClassDefFoundError: *.java Even though these programs really have no problem at all. Here are some solutions for you: ...
It is difficult to write programs that behave correctly in the presence of exceptions. We describe a dataflow analysis for finding a certain class of mistakes made while programs handle exceptions. These mistakes involve resource leaks and failures to re
