certifications, such as scjp, scjd, and scwcd, which can be used to evaluate the basic skill of developers.

In addition to professional training, experience is also a condition for an excellent architect, and the program is also certified, such as PMP. Maybe you will think that Java is a very popular.

Java basics-java language overview, java-java Overview I. Two types of computer programming 1. process-oriented model-linear execution is characteristic, and code is considered to act on data. 2. object-oriented model-organizes programs around its data (that is, objects) and the interfaces defined for this data.

We know that in Java, subclasses can inherit the parent class, and if the subclass declares a method that has the same name as the parent class, we all know that if you rewrite it, but in fact it is divided into two cases, that is, methods and variables in the inheritance of the cover and hide problems, these conceptual things seem boring, But in the interview or SCJP certification questions around these ar

The constant_string_info structure provides the Unicode Character Sequence that constitutes a string literal constant. 4) To generate a string literal constant, Java Virtual Machine checks the Character Sequence given by the constant_string_info structure: A) if the string instance with the same character exchange content as the constant_string_info structure has call

techniques can be categorized according to the confusion target, respectively, as follows:Symbol Confusion (Lexical obfuscation), data obfuscation, control obfuscation, and preventive Confusion ( Prevent transformation). Case Analysisin practice, protecting a large Java program often requires a combination of these methods, rather than a single use of one method. This is because each approach has its weaknesses and application environment. Using thes

phase, do not pay attention to the details, as long as the basic Java Grammar has a holistic understanding, can read the sample source code can be. The next step is the deductive phase, the application of the grammar knowledge to write a simple program. It is best to rely on their own memory, the grammar points are used again (write code best use Notepad), unfamiliar to their own grammar to re-read, with the compiler to check syntax errors. The goal
