Java和 Swift 的区别

1.Java：
Java是一种面向对象、平台独立、并发的通用编程语言和计算平台，最早由 Sun Micro System 于 1995 年开发，由 James Gosling 开发。

一些使用Java编程语言的公司是优步、谷歌、Netflix、Pinterest、Instagram 和亚马逊等。

Java的特点：

• 简单的语言
• 便携语言
• 平台无关语言
• 面向对象
• 安全的
• 强壮的
• 表现出色
• 多线程

使用Java 的好处：

1. 稳定性和开源社区
2. 安全风险不足
3. 自动内存管理
4. 企业计算标准
5. 平台独立性

使用Java 的缺点：

1. 冗长而复杂的代码
2. 表现不佳
3. 支付商业许可
4. 单范式语言
5. 更少的机器交互

2.斯威夫特：
Swift 是由 Apple Inc 开发并于 2014 年首次发布的出色且本能的编译型通用编程语言。它用于开发适用于 macOS、iOS、watchOS、tvOS 等的软件应用程序。它是由 Chris Lattner 开发的。
一些使用 Swift 编程语言的公司有 Uber、Slack、Robinhood、Accenture 和 Lyft 等。

斯威夫特的特点：

• 强大而快速
• 函数式编程模式
• 现代语言
• 安全可靠
• 富有表现力
• 更好的速度

使用 Swift 的好处：

1. 开源社区
2. 应用程序的可扩展性
3. 支持多种设备
4. 易于与 Objective-C 集成
5. 提高性能和安全性

使用 Swift 的缺点：

1. 语言还很年轻
2. 缺乏对早期 iOS 版本的支持
3. 有限的人才库/迅捷的程序员
4. 兼容性问题
5. 早期版本有速度问题

Java和 Swift 的区别：

S.NO.	JAVA	SWIFT
01.	Java is an object-oriented, platform independent, concurrent general purpose programming language and the computing platform which was first developed by Sun Micro System in the year 1995.	Swift is a great and instinctive, compiled and general purpose programming language which is developed by Apple Inc and first released in the year 2014. It is used to develop software applications for macOS, iOS, watchOS and beyond
02.	Application servers, web applications, android applications, Desktop applications and Enterprise applications etc. can be developed using java language.	By using Swift programming language we can develop iOS mobile and Television applications, macOS desktop applications etc.
03.	Syntax of Java programming language is more verbose and little complex.	While syntax of swift language is easier to learn and start work on it
04.	During inheritance, it uses extends keyword for example class Child extends Parents.	During inheritance, it uses : symbol for example class Child : Parent
05.	It uses constructors like same name as of class for example Simple( ) where the class name is also Simple.	It uses constructors like init( ) method.
06.	In java, object creation looks like Simple obj=new Simple();	In Swift, object creation looks like Var obj : A=A
07.	Java is one of the old programming language having more community support.	Swift is one of the new programming language having less community support as compared to java.
08.	Java has complex syntax and code readability as compared to swift language.	Swift has easy syntax and code readability as compared to java language
09.	Some of the companies which use Java programming language are Uber, Google, Netflix, Pinterest, Instagram and Amazon etc.	Some of the companies which use Swift programming language are Uber, Slack, Robinhood, Accenture and Lyft etc.
