In case of Interfaces, when I assign an interface reference variable an implementing class object I can call methods defined in the Object class like toString(), get Class(), equals() etc. Does this mean that Object is superclass of an interface also ( t

Variable usedinlambda expression should be final or effectively final 翻译过来就是说在lambda表达式中只能引用标记了 final 的外层局部变量或者虽然没有显式定义为final,但实际上就是一个final变量,否则会编译错误。 那么显然在上面的代码中的otherMap变量,在Map<String, List<Phone>> otherMap = new HashMap<>...

java 中局部内部类和匿名内部类访问的局部变量必须由 final 修饰,以保证内部类和外部类的数据一致性。但从 Java 8 开始,我们可以不加 final 修饰符,由系统默认添加,当然这在 Java 8 以前的版本是不允许的。Java 将这个功能称为 Effectively final 功能。

However, all instances representing a type variable must be equal() to each other. As a consequence, users of type variables must not rely on the identity of instances of classes implementing this interface. Added in 1.5. Java documentation for java.lang.reflect.TypeVariable....
