Synchronized can ' t appear on a method declaration in an interface.Synchronization cannot appear on the method of an interface. Inner classes is just syntactic sugar, so locks on Inner classes has n

To test-nonidentical objects for equality, pass one of the them to the Equals () method of the other: All objects inherit a Equals () method (from Object), but the default implementa‐tion simply uses = = to test for identity of references, not equality of content.

Either, directly re-implementing the JVM, directly explaining the language3,java and C + + differences: Java's function call is virtual by default Java always passes the value of the Java does not support multiple inheritance Java does not have operator overloading 4,java ignores all whitespace, tab, line breaks, and so on,

The relationship between the JAVA8 function reference and the lambda expression => function Reference is a simplified lambda expression that infers only the function, parameter, and return value compiler that appears. > Actually this grammar and lambda expression is exactly the opposite, NBSP;LAMBDA expression represents an anonymous method, which is the absence of a function name, giving only parameters and method bodies. Then the existing function comes in handy, the existing function has th
