Lazy developers use the generic Exception class in thethrowsclause of a method. Doing so is not a Java exception handling best practice. Instead, always explicitly state the exact set of exception a given method might throw. This allows other developers to know the various error handling routines...

Doing this not only returns “null” instead of handling or re-throwing the exception, it totally swallows the exception, losing the original cause of the error forever. And when you don’t know the reason for failure, how would you prevent it in the future? Never do this !! 3.2. Decla...
简单分析一下上面代码的字节码指令:字节码指令 2 到 8 会抛出 ArithmeticException 异常,该异常是 Exception 的子类,正好匹配异常表中的第一行记录,然后跳转到 13 继续执行,也就是执行 catch 块中的代码,然后执行 finally 块中的代码,最后通过 goto 31 跳转到 finally 块之外执行后续的代码。 如果try 块中没有...

Exception Handling Best Practices Java Exception Handling Overview We don’t like exceptions but we always have to deal with them, great news is that Java Exception handling framework is very robust and easy to understand and use. Exception can arise from different kind of situations such as wron...
Java providesexception handlingto handle these scenarios usingtry-catchblocks. There are some set of rules or best practices which we need to follow in exception handling. Let’s discuss some best practices below Practice 1 Execute Clean up Resources in a Finally Block or Use a Try-With-Resourc...
What’s most important in exception handling is information that helps create an informed response. Exception classes hold information. You can design them to be packed with information in addition to the bare-bones stack trace information provided by default. You might include values of parameters ...
