How does type inference work in Java?

Can you explain how type inference works in Java?

Sure! Type inference in Java allows the compiler to determine the type of a variable automatically based on the context.

Can you give me an example of type inference in action?

Absolutely! For instance, when you use the var keyword in Java 10 and later, like var list = new ArrayList<String>();, the compiler infers that list is of type ArrayList<String>.

Are there any limitations to type inference?

Yes, type inference has limitations. For example, it cannot infer types in all situations, such as when the type is ambiguous or when using lambda expressions.

How does this compare to type inference in other languages?

In languages like Kotlin or TypeScript, type inference is often more powerful and can handle more complex scenarios than in Java.
