How to reduce the number of bugs in Java encoding

As we all know, The Java programming language is an indispensable part of the enterprise in the IT industry. Regardless, from Web applications to Android apps, this language has been widely used to develop complex functions in a variety of applications and code. But when writing code, bugs are always the number one problem for every practitioner. Today, I would like to share with you a few of the best practices to reduce the number of bugs in Java development, hoping to bring you some help.

　　Do not rely on initialization

In Java programming, developers often rely on constructors for object initialization. But this is actually a common misconception. We can implement object assignment in many ways without calling the constructor. For example, to declare all variables private, to access objects outside the class, you can use the get and set methods, write a new private Boolean variable for each object, and initialize it, and write a non-constructor class that will ensure that each object is initialized before accepting the call, and so on.

　　Avoid using internal classes

In general, developers use internal classes when other classes are needed within the same package. These inner classes are typically accessible to all classes within the same package, and the issues that might arise are already mentioned in the predefined Code scope section. Therefore, also use internal classes only when necessary.

　　Always pre-Define a range

Most developers rely entirely on the scope of the package itself, and in fact we should insist on pre-defined code scope. Many classes themselves are not completely closed, which means attackers can attack them. Hackers can use a single vulnerability to insert their own classes to extract sensitive information from code. The JVM is not closed by default, but allows classes to be closed within the package.

Of course, no one can 100% grasp all the mysteries of Java, but the above programming principles and practices, will be able to help you from a certain level to effectively reduce the number of bugs in the code.
