Java – @ suppresswarnings annotation benefits

2020-08-21 • Java

@Is the suppresswarnings annotation for clearer code, or is there any performance improvement or advantage by adding it?

Or we can do this to reduce compilation time

Solution

@The suppresswarnings annotation type allows Java programmers to disable compilation warnings for certain parts of the program (types, fields, methods, parameters, constructors, and local variables) Usually warnings are good But in some cases, they can be inappropriate and annoying Therefore, if necessary, the programmer can choose to tell the compiler to ignore these warnings

It has nothing to do with performance

The developer who wrote the code knew it was always safe and decided to use @ suppresswarnings ("unchecked") to suppress compile time warnings

As others have mentioned, it's just trust between developers and the code they write
