What are the benefits of using var in Java?

Using var in Java allows for type inference, making code more concise and readable. It reduces verbosity while maintaining type safety.

Can you give me an example of using var?

Sure! Instead of writing String name = "John";, you can simply write var name = "John"; and the compiler infers the type.

Are there any downsides to using var?

One downside is that it can make the code less clear in some cases, especially if the type is not obvious from the context.

When was var introduced in Java?

Var was introduced in Java 10 as part of the local variable type inference feature.

Is var only for local variables?

Yes, var can only be used for local variables and cannot be used for method parameters, return types, or class fields.
