1.Java data Types Before we introduce the automatic boxing and unpacking of Java, let's look at the basic data types of java.In Java, data types can be divided into two major types, Primitive type (base type) and reference type (reference type). the value of the base type is not an object , and methods such as ToString (), Hashcode (), GetClass (), Equals () of the object cannot be called. So Java provides a wrapper type for each of the basic types. A

Re-discussion type Before you discuss boxing (boxing), it's important to figure out why the value type differs from the reference type. What is the difference between an instance of a value type that contains numeric values, and an instance of a reference type that points to an object? In addition to the memory required to store objects, each object has an object header that provides basic services for ob

();}}Code Analysis:We first defined a person class that contains 2 attributes, age and name, where age is a value type, and name is a string reference typeIt then initializes 2 person classes, Zerocool and Anders, assigns values, and then modifies the age and nameAt this time, due to the characteristics of the value type, we just allocated a resource to zerocool.age on the stack, and there was no relationship between the later declared age. So age is the same.Modifying the name is not the same,

Automatic boxing and unboxing functions in fact, the compiler to help you, the compiler at compile time according to the syntax you write, decide whether to do boxing or unboxing action. For example: Integer i = 100; The equivalent compiler automatically compiles the following syntax for you: integer i = new integer (100); So the function of automatic boxing an

The examples in this article describe C # Boxing and unboxing operations. Share to everyone for your reference, specific as follows: 1. Boxing in C # Boxing in C # is an implicit conversion of a value type to type object, using a copy of the value instead of a reference in the conversion process , as can be seen from the following example: Using System;

the heap, which is more efficient than the stack, which is why Java retains the base type. The wrapper class creates objects that can be used by some useful methods provided by the API. More powerful. 2, automatic boxing and automatic unpacking So let's analyze the process of integer i = 5; Before jdk1.5, such code was wrong and had to be implemented through the integer i = new integer (5); After jdk1.5, Java provided the automatic
