Java vs. Python
Java and Python are both popular programming languages. Each has its own strength, when it comes to programming. In my research, I have tried to elaborate the main differences and similarities, as well as some of more specific and detailed differences.
General Comparison: Java Python
1. Java runs faster and its compiler has less runtime. Python is slower than java.
2. Java has longer development time with more detailed code. Python programs and codes are typically 3-5 times shorter than java
3. Java is static language (Explained later) Python is a dynamic language
4. Java is pure OOP (Object Oriented Programming Language) Python is mixture of multi-paradigm (it supports procedural, functional & OOP)
5. Java Supports Overloading Python also supports

Specific Comparisons
1: Subprograms
A program can be broken down into several smaller units, which has a particular task or has a repeated task. The complete program is thus made up of multiple smaller, independent subprograms that work together with the main program.

1. A Sub Programs in General:
Python is different type of programming languages in which it uses indentation to separate code into blocks or sub program. Java, like most other languages, uses curly braces to define the beginning and end of each function and class definition.
Java Python if ( a > b )
{
a = b; b =
It also includes pair programming where two developers work on the same pc, while one typing and other offered advice. This improved programs productivity and decrease error.
Software systems are discrete-state systems that do not have repetitive structures. The mathematical functions that describe the behaviour of software systems are not continuous, and traditional engineering mathematics do not help in their verification." In other words some software can be so large that thorough testing can be almost impossible and so bugs in the software can go unnoticed. An example of this was when an Atlas-Agena rocket veered off-course when it was ninety miles up. Ground control had to destroy the $18.5 rocket.
The Ada language is the result of the most extensive and most expensive language design effort ever undertaken. The United States Department of Defense (DoD) was concerned in the 1970¡¦s by the number of different programming languages being used for its projects, some of which were proprietary and/or obsolete. Up until 1974, half of the applications at the DoD were embedded systems. An embedded system is one where the computer hardware is embedded in the device it controls. More than 450 programming languages were used to implement different DoD projects, and none of them were standardized. As a result of this, software was rarely reused. For these reasons, the Army, Navy, and Air Force proposed to develop a high-level language for embedded systems (The Ada Programming Language). In 1975 the Higher Order Language Working Group (HOLWG) was formed with the intent of reducing this number by finding or creating a programming language generally suitable for the department's requirements.
Today, the world is changing fast in many ways, and the most rapid change that is seen within our society is technology. It is imperative that businesses stay on top of what is new and how they can better their company’s outlook by presenting their information in the fastest and most reliable ways. With the two major computer programming languages of today, C++ and Java, which is better for businesses to be able to acquire such speed and consistency?
Component Based Architecture creates a system that is easily extensible, promotes software reuse and intuitively understandable. A component often relates to an object in Object Orientated Programming. The RUP provides a systematic way to build this kind of system, focusing on producing an early executable architecture before committing full resources on a project.
Decomposition is one of the cornerstones when it comes to computer science. Decomposition is breaking down a problem or system into smaller, more manageable parts that can be solved or fixed separately. An example of this would be a software company having a team that work on the same project all together but working on different parts at the same time to get it completed in a much faster rate. Problems are much easier to understand once they are split apart e.g. if you wanted to know how a car works it would take a much longer time if it was all built, however, if the car was split into different parts you would understand how it works quicker and most importantly easier.
A sub program also known as subroutine is a set of instructions set by a coach or individual that is designed to perform a regularly used operation within a program.
Many different types of programming languages are used to write programs for computers. The languages are called "codes". Some of the languages include C++, Visual Basic, Java, XML, Perl, HTML, and COBOL. Each of the languages differs from each other, and each is used for specific program jobs. HTML and JAVA are languages used to build web pages for the Internet. Perl and XML can produce codes that block students from getting on certain inappropriate web pages on their school server. One of the most prominent programming languages of the day would have to be C++.
Python is a programming language made easy to code and read. Python is what is called an interpreted language, which the computer runs right away. This allows the programmer to make changes in the code quickly and efficiently with as few lines of code as possible. It is derived from C, but is an easier to read. It uses whitespace to delimit code, such as spaces or tabs to organize data. At the end of the lines, neither semicolons nor curly braces are necessary, making it an easy language to read. Fullscreen games can be made with Python, if one manages to access the correct libraries.
However, Python has its ways of showing these newcomers or experienced users a path to guide them correctly using many types of errors in which the program holds instock, these errors are known as the syntax, run-time, and logical errors. In Python, a Syntax error is a used to detect mistakes in the program, and terminate the programs execution until resolved. Some common Syntax error examples are typographical errors like mismatched parentheses or string quotes or faulty indentation etc.. and like syntax errors, The run time error is a bit harder to detect, mostly remaining unseen until the program is actually launched revealing it to the user and making the code faulty and unable to be executed, making the run time error the most troublesome of the three errors.The logical error in Python is used similar to as the Syntax and the run time errors, it is the easiest of the three because it detects the errors during the translation phase in which that means that the interpreter reads the Python source code and translates it into executable machine code however, if a mistake is located during the source code, it will show the user the exact spot on where the error was located, making the logical error the easiest to repair out of all of the other
The field of Computer Science is based primarily on computer programing. Programming is the writing of computer programs using letters and numbers to make "code". The average computer programer will write at least a million lines of code in his or her lifetime. But even more important than writting code, a good programer must be able to solve problems and think logicaly.
Imperative language includes order and command. While using imperative language we order others to do something. We also give commands to anybody.
Software, such as programming languages and operating systems, makes the details of the hardware architecture invisible to the user. For example, computers that use the C programming language or a UNIX operating system may appear the same from the user's viewpoint, although they use different hardware architectures. When a computer carries out an instruction, it proceeds through five steps. First, the control unit retrieves the instruction from memory—for example, an instruction to add two numbers. Second, the control unit decodes the instructions into electronic signals that control the computer.
Computer programming can as well be defined as a process that leads from an original formulation of a computer problem to execute problems. Computer programming is also referred to as programming. It encompasses other activities such as understanding, analysis and generally solving problems that result in algorithm, verifying the algorithm requirements and coding algorithm in a target program language. The program also involves the implementation of the build system and managing derived artifacts like computer programs machine codes. Most often, the algorithm is represented in human-parseable languages such as Java, Python, Smalltalk among others.
Software engineering was suggested at a NATO conference in 1968 to talk about the software crisis. “Software crisis” was the name give to problems encountered in the development of large and complex systems . In the early 1970s, notions of structured programming started coming up. In the late 1970s, early
