This article will explain in detail how Java only uses exceptions in exceptional cases, Xiaobian feels quite practical, so share it with you for a reference, I hope you can gain something after reading this article.

Use exceptions only in exceptional cases

This is primarily to avoid using exceptions for normal control flow.

For example, instead of using an exception to terminate the loop control flow:

try{ Iterator iter = ...; while(true) { Foo foo = i.next(); ... }} catch (NoSuchElementException e){}

Regular iterations over collections should be used:

for(Iterator iter = ...; i.hasNext();){ Foo foo = i.next(); ...}

I didn't find any examples of using regular control flow exceptions.
