See the unchecked examples on using the unchecked keyword.ExampleThis sample shows how to use checked for a non-constant expression. The overflow is reported at run-time.复制 // statements_checked.cs using System; class OverFlowTest { static short x = 32767; // Max short value static ...
and I'll bet it was because people saw unchecked exception specifications in C++ and thoughtthatwas a mistake (I know I did, for the longest time). At this point, I feel like checked exceptions are (1) an untried experiment when they were put into Java (unless you know of some other...

There are two types of exceptions: checked exception and unchecked exception. In this guide, we will discuss them. The main difference between checked and unchecked exception is that the checked exceptions are checked at compile-time while unchecked exce
