There's no dropping of type requirements in Java, `var` only saves typing.
When you use `var`, everything is as statically typed as before, you just don't need to spell out the type when the compiler can infer it. So you can't (for example) say `var x = null` because `null` doesn't provide enough type information for the compiler to infer what's the type of `x`.
var does absolutely nothing to make Java a less strictly typed language. There is absolutely no dropping of the requirement that each variable has a type which is known at compile time.
Automatic type inference and dynamic typing are totally different things.
