// Can't use the local variable type inference with fields
public class SomeClass {
    // Not allowed, var is only available for local variables
    var property = "";
}

// Can't leave values unitialzed
var uninitialized; // No way to infer the type

// Can't just assign null to var to reassign later (but workaround available)
var nullVariable = null; // No way to infer the type, also not legal
var castedNull = (String) null; // This is legal, inferred type will be String
