In C ++, in some cases, it is convenient to allow a specific non-member function to access a private member of a class while still blocking normal access. For example, an overloaded operator, such as an input or output operator, often needs a

Constructor Differences between constructors and MethodsSummaryTo learn Java, you must understand the constructor. The constructor provides many special methods, which are often confusing for beginners. However, there are many important differences

Code reviews are one of the most important ways to eliminate bugs, which are especially effective in most cases. Because the code review itself targets objects, it is to overlook the problems and bugs of the entire code in the test process. In

Different functions:The constructor is designed to create an instance of a class; the name is the same as the class; there can be no modification of the access: public, protected, private, or no adornments, no modification of the following

Six ways to read a properties file using the J2SE API: 1. The load () method using the Java.util.Properties class Example: InputStream in = Lnew bufferedinputstream (new FileInputStream (name)); Properties P = new properties (); P.load (in); 2.

Although Google's guava a certain encapsulation of Java IO operations, but it is more in favor of the collection, concurrency and caching, in the actual project, I like guava very much, I also like the Apache Toolkit Org.apache.commons.io, which

The Synchronized keyword, which represents a lock on this method, is equivalent to whichever thread (such as thread A) is running to this method, checking that there are other threads B (or C, D, etc.) using this method (or other synchronization
