Python and Java Are programming languages widely used in this era . however , And Java Language comparison ,Python The language is more efficient in encoding lines , It starts with a simple question , For the same purpose Python comparison ,java You need more coding lines . however , Why do people still use Java Language .
Static type
Java Provides type protection , All possible errors can be solved in accumulated time , therefore , The potential for runtime errors is reduced , instead of Python Capture at runtime . Last , This highlights , Monitoring large applications becomes easier . Even though Python It's a powerful language , But there will be errors at run time , Runtime errors are more difficult to investigate than order timing errors .
Besides , And Python comparison , Check Java The code is very simple , This is valuable when a group of developers are dealing with similar tasks .Java Software developers will quickly understand each other's code , Because everything is clearly stated . However ,Python Developers face some problems when examining their code , Because when the various markers become known , Everything is represented or occurs at runtime .
Execution and speed
In terms of speed and execution , without doubt ,Java Than Python Have stronger advantages . Thanks a lot JIT( Real time compiler ), It can quickly convert Java Bytecode to local machine code . also ,Java The rendering of can be accelerated to equal C/C++. and Python Much slower in execution and speed ,Python Unlike Java That provides local execution and speed .
More common in mobile development
These two languages have a place in almost every computing field , Including scientific computing 、 desktop 、 Data analysis 、Web And artificial intelligence .
however , The cell phone is Java One of the areas with strong influence , Far more than any programming language in this period . Running on the Android equipment ( Including mobile phones or tablets ) A large number of applications on are based on Java Developed . Besides , A large number of embedded devices are used Java. however ,Python Not much help in the field of mobile phones . therefore , About mobile application development ,Java Is an alternative , instead of Python.
Parallel programming and concurrency
Java Concurrency has been fully supported since the initial release . in the meantime , It also adds many excellent features about multithreading and concurrency . And Python Programming languages ,Java It can also better help parallel programming . Because the global interpreter lock is contained in a specific CPU Running on Python,Python More like a regular language .
Powerful database connection
In terms of database connectivity ,Java be better than Python. because Java Database connection ,Java Have a strong database connection layer . Again ,Java Database connection is widely used in Java Procedure and SQL and SQOOP And so on . However , And Java Of Java Database connection compared to ,Python The database mode layer of is weak .
The ecological system
Java and Python There are several robust frameworks and libraries , However ,Java Is the inevitable winner of enterprise application development , Rich and mature frameworks and libraries are prepared for enterprises and high-volume applications , These frameworks and libraries are supported and maintained by a large community of enterprise developers , therefore , The development of enterprise applications becomes easier . Important ecosystems are targeted by many languages Groovy、JVM Such as Scala、Clojure and Kotlin And so on . Besides ,Java It's similar in Maven and Gradle Powerful dependency management tools for .
Conclusion
In this article , We introduced the use of Java instead of Python Some reasons for programming languages ： Information about parallel programming and concurrency as well as strong database connectivity ,Java The ecosystem needed for programming , With this function , You can easily put java Programming for different purposes .
