Array is a data type that basically exists in all languages. It represents a set of data of the same type, has a fixed length, and occupies a continuous space in memory. In languages ​​such as C and C++, the definition of arrays is concise and clear, but in Java there are indeed some confusing features. This article attempts to analyze these characteristics. Are arrays in Java objects? Both Java and C++ are object-oriented languages. When using these languages, we can directly use standard class libraries, or we can use object-oriented features such as composition and inheritance to build our own classes, and create objects based on the classes we build. So, should we consider this question: In object-oriented languages, are arrays objects? To determine whether an array is an object, first clarify what an object is, that is, the definition of an object. At a high level, an object is an instance created from a class and represents a specific individual in a class of things. Objects have various properties and have some specific behaviors. At a lower level, from the perspective of a computer, an object is a memory block in the memory. This memory block encapsulates some data, which is the various attributes defined in the class. Therefore, for

## Introduction: 1. What is an array? I forgot which book I saw a sentence like "All data structures are the evolution of arrays". It actually makes sense when you think about it, because the computer's memory is actually a linear storage space. Java sample code: int[] array = new int[5] Ignoring the object header information and array length information, the JVM will allocate 20 bytes of memory space in the heap when executing, which looks like this: Such a data structure can It is very convenient to access data through array subscripts, but when searching, you need to traverse the array, and the average time complexity is O(n/2). When the amount of data..

Detailed code examples for removing duplicate method sets from Java arrays

Java array introductory tutorial: 10 recommended zero-based introductory tutorials on java array

Introduction: Often used, sometimes not just simple basic types, which can be set When deduplicating a set, we often use our own custom types. Here’s an example (I’m taking int as an example here): Method 1. This is similar to the selection sorting algorithm. First, we take the value of i, and then change i All subsequent duplicates are removed. The specific implementation is as follows: [java] view plain copy import java.util.List; imp
