distinguish between these, kinds of equality. One of the "identical" when talking about equality of references and the word "equal" when Talking about a distinct objects that has the same content. 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.

locked. Locking an object[] doesn ' t lock the individual objects.Locks a object[] array, and cannot lock every object within the array. Primitives is not mutable, so they can ' t (and don ' t need to) be locked.Native types are immutable, so they cannot (and do not need to) lock. 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

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

up when a new entry is added to the cache. The Linkedhashmap class can implement the latter through its Removeeldestentry method. For more complex caches, you must use Java.lang.ref directly.A third common source of memory leaks is listeners and other callbacks.If the client registers callbacks in its own implementation of the API, but does not explicitly unregister, they will accumulate unless some action is taken. The best way to ensure that callbacks are immediately treated as garbage collec

Compared with the previous version, the content of the update is more, overall close to the entire length of 1/2, and this is one of the reasons why the book came to a belated. Specifically, the 5th edition is updated in the following sections: The first part of the chapter on functions

set at the beginning of the instance object creation. objects created from direct amounts of objects use Object.prototype as their prototypes, and objects created by new use the prototype property of the constructor as prototypes. Objects created by Object.create () use the first parameter as a prototype.To detect whether an object is a prototype of another object (or in a prototype chain), use the isPrototypeOf () method.var p={x:1}; // defining a prototype object var o=object.create (p);

two chapters are very abstract and difficult to understand, and the code examples in the book are closely related to the previous content, because the knowledge points in the previous chapters are not thorough enough to understand the code. There is always a need to revisit the textbook to review the previous content to get a little bit of code.Learning progress Bar lines of code (new /Cumulative) Blog volume ( new/cumulative) Learning time (new/cumulative) I

During the Spring Festival read the next "java:the complete Reference" found this writing in simple, I think a question, the book a lot of content we also know, but why we can not write such a book, so comprehensive, so systematic, so simple and easy to understand. Have to admire Herbert Schildt programming skills, need to mention is Herbert Schildt wrote a lot of Java and C, C + + books, he is the C, C + +, Java
