In the early years of computing, the choice of the first language for a program was often decided by the work environment. Typically information technology divisions with the specialized needs assembly language for a specific hardware system were the usual situation. Nowadays java and python have become more popular. In this article, there is a complete comparison between java vs python. But firstly we read some history.

Programming in a higher-level language such as Fortran or Cobol became more common over time as more versatile computing platforms and elaborate computing problems emerged.

The choice of first programming language was determined primarily by the curriculum designers in the universities when they began to develop computer science programs.

The first language was decided with emphasis on the pedagogical value of the language rather than its popularity or practically in developing real-world applications.

As might be expected in the academic world, there was and still is a diversity of opinion on what the first language should be.


The report observes that rather than a particular paradigm or language coming to be favored over time, the past decades have only broadened the list of programming languages.

These languages are now successfully used in beginners’ courses. In the 1970s and 1980s, Pascal became the language taught most often in beginner’s programming courses.

 In recent years, the increased demand for programming courses for liberal arts students has led to the development of what is termed CSO courses ( with CS1  courses aimed for CS majors).

Java vs Python differences: 

In this section we will learn about  the following:

1: Java vs Python differences

2: Java vs Python compiler

3: Java vs Python performance 

4: Java vs Python syntax

Python vs Java differences:

1: Python supports many (but not all)  aspects of object-oriented programming. But it is possible to write a Python program without making any use of object-oriented concepts.

Java supports only object-oriented programming.

This is one of the major  Java vs Python differences.

2: Python is designed to be used interpretively. A Python statement may be entered at the interpreter prompt (>>>), and will be executed immediately.

 on the other hand, programs written in Java must be explicitly compiled into bytecodes, though an IDE may do this automatically in a way that is transparent to the user.Java does not support direct execution of statements though there are tools like doctor Java that support this.

Python vs Java compiler( or java vs python performance):

Java has just in time (JIT)  compiler and support for concurrency. These two are responsible for the efficiency of Java. The JIT compiler is part of the Java Runtime Environment.

The JIT compiler compiles bytecode into native machine code “just in time” to run which improves the performance of Java. The compiled code is directly called by Java Virtual Machine (JVM). Compiling does not require professor time and memory usage since the code is not interpreted.

As compared to Java programs, Python is interpreted which slows down the Python programs during runtime. The workload of the interpreter is increased during runtime, because of determining variable types. Also, memory usage is very high. 

Python vs Java syntax:

1:  Python is dynamically typed:

                               A variable is introduced by assigning a value to it. for example some variable=42.

A variable that has been assigned a value of a given type May later be assigned the value of a different type. example some variable equal = 42 or some variable= “hello world”.

2:  Java is statistically typed:

        A variable must be explicitly declared to be of some type before assigning a value to it, through declaration and assignment may be done at the same time. Example:  int some_variable; int some_variable =42;

3: Python definite looping statements have the form for variables in the expression. Example: 

For i in range(1,10) something( i takes on values 1,2,3,4,5,6,7,8,9).

4: Java has two kinds of definite looping statements. One has the form for (variable in the collection)

Example:  for (P in pixels)


5: A Python function is called by specifying its name followed by a list of actual parameters( that must be the same length as of the list of formal parameters). Example:  discr(1,2,1)

6: A Java function is called by specifying the object or class to which it is to be applied followed by a dot, then it’s a name followed by a list of the actual parameter( that must be the same length as the list of formal parameters, with each actual parameter compatible with the declared type of the corresponding formal parameters).

Example:    Solver.discr (1,2,1)

Java vs python popularity:

Prevalence has consistently been a game between these two dialects, as they’ve been a nearby rival in the best 3 places of fame, alongside javascript. Prior to Javascript transformation, Java was the main most mainstream language. When Javascript first turned out, the organizers picked a name near Java to make it gain footing. 

According to Github’s October, Java was the second most utilized language on Github followed by Python. 

In Stackoverflow’s 2018 designer review, Python has delegated the quickest developing programming language in the wake of taking over C# recognize this year and outperforming PHP a year ago. Java is as yet positioned above Python being mainstream with 45% of engineers while Python is at 39%, anyway that hole is shutting. 

It is sheltered to state that the two dialects dwell around a similar territory in prevalence.


Java and Python are both competent and famous dialects, so there won’t be an absence of assets once you pick one and leave on your excursion. 

In case you’re new to programming, it’d be smarter to stay with Python since it’s extremely simple and utilizations English-like sentence structure, it’s utilized in numerous Computer Science basic courses far and wide. 

Be that as it may, if you will probably fabricate undertaking level applications originating from a C/C++ world, at that point Java would presumably feel really recognizable to you. Everything goes down on what you intend to construct and where you want to travel with your new expertise.
