One of the first projects developed using Java was a personal hand-held remote control named Star 7. At about the same time, the World Wide Web and the Internet were gaining popularity.
Principles There were five primary goals in the creation of the Java language: Nature of the Java Language A programming language As a programming language, Java can create all kinds of applications that you could create using any conventional programming language.
A development environment As a development environment, Java technology provides you with a large suite of tools: An application environment Java technology applications are typically general-purpose programs that run on any machine where the Java runtime environment JRE is installed.
A deployment environment There are two main deployment environments: The other main deployment environment is on your web browser.
Most commercial browsers supply a History of programming languages essay writer technology interpreter and runtime environment. Some Features of Java: The JVM provides the hardware platform specifications to which you compile all Java technology code. This specification enables the Java software to be platform-independent because the compilation is done for a generic machine known as the JVM.
The bytecode is independent of any particular computer hardware, so any computer with a Java interpreter can execute the compiled Java program, no matter what type of computer the program was compiled on.
Garbage Collection Many programming languages allow a programmer to allocate memory during runtime. However, after using that allocated memory, there should be a way to deallocate that memory block in order for other programs to use it again.
This can be difficult at times since there can be instances wherein the programmers forget to deallocate memory and therefore result to what we call memory leaks. In Java, the programmer is freed from the burden of having to deallocate that memory themselves by having what we call the garbage collection thread.
The garbage collection thread is responsible for freeing any memory that can be freed. This happens automatically during the lifetime of the Java program.
The JRE runs code compiled for a JVM and performs class loading through the class loadercode verification through the bytecode verifier and finally code execution.
The Class Loader is responsible for loading all classes needed for the Java program. It adds security by separating the namespaces for the classes of the local file system from those that are imported from network sources. This limits any Trojan horse applications since local classes are always loaded first.
After loading all the classes, the memory layout of the executable is then determined. This adds protection against unauthorized access to restricted areas of the code since the memory layout is determined during runtime.
After loading the class and layouting of memory, the bytecode verifier then tests the format of the code fragments and checks the code fragments for illegal code that can violate access rights to objects. After all of these have been done, the code is then finally executed.
Phases of a Java Program The first step in creating a Java program is by writing your programs in a text editor. Examples of text editors you can use are notepad, vi, emacs, etc. This file is stored in a disk file with the extension. After creating and saving your Java program, compile the program by using the Java Compiler.
The output of this process is a file of Java bytecodes with the file extension.Writing; The Evolution of C++ as a Programming Language Essay I read through many books and sources to help make the history of language a little more clear and found many interesting ideas. I found that something as simple as the way you use your hand could shape the brain, language, and human culture (The Hand).
More about The. There are more than 8, total programming languages, according to HOPL (History Of Programming Languages). As demonstrated previously, the many thousand programming languages developed over the years is a result of the growing number of applications and uses for languages and also updated and revised versions of existing programming languages.
A History of Computer Programming Languages Ever since the invention of Charles Babbage’s difference engine in , computers have required a means of instructing them to perform a specific task.
This means is known as a programming language. The first high-level programming language was Plankalkül, created by Konrad Zuse between and The first high-level language to have an associated compiler, was created by Corrado Böhm in , for his PhD timberdesignmag.com first commercially available language was FORTRAN (FORmula TRANslation); developed in (first manual appeared in , but first developed in ) by a .
History of Programming Languages. Software development process originally consisted only of the coding phase. The computer was mainly used in the early days in scientific applications – an application was programmed by one person. The problem to be solved, .

The most important differences between object-oriented programming languages and generations programming languages are: object oriented computer programming is generally accepted as the first language to have the primary features of an object-oriented language 2 / Programming language First Generation Programming is a machine language.
First Generation Programming is a machine language. It only understands zeros and ones, so we say machine languages are binary. Second Generation Programming is also called assembly languages that use simple words in place of zeroes and ones.
