Learning Management system from impetus

In June 1962, the first American space probe to Venus (Mariner I) went off course and had to be destroyed because of an error in one of the guidance programs in its onboard computer.

One statement of the program, though syntactically correct, had a meaning altogether different from that intended by the programmer. Although few bugs have such spectacular effects, errors in computer programs are frequent and influential. There has been substantial effort recently to apply mathematical rigor to the programming process and to enable the accuracy of the machine to compensate for the error-prone human mind.

In the late nineteenth and early twentieth century, mathematics underwent a process of formalization and axiomatization, partially in an effort to escape from paradoxes and logical errors encountered by previous generations of mathematicians. A similar process is underway in the development of a logical theory of programs.’ This theory has already made our understanding of programs more precise and may soon facilitate our construction of computer programs as well. 

Logical techniques are being developed 

• to prove programs correct, 
• to detect programming errors, 
• to improve the efficiency of program operation, 
• to extend or modify existing programs, and even 
• to construct new programs satisfying a given specification; 

 In the last decade, this field of research has been extremely active; it now has the potential to exert a deep influence on the way computer programs are produced.

Java is an object-oriented programming language, created in 1995 by Sun Microsystems. It was designed as an alternative to the extremely difficult C ++ distinguished by the absence of both systematicity and logical restrictions in software development. The new approach also had to solve other urgent issues, like security, cross-platform, versatility, etc.

Features of Java 

• Versatility. Java applies for both frontend and backend components development. Moreover, IT-specialists use it to design narrow-profile software for cars and smart houses, as well as solutions for banks and payment systems.
• Simplicity and Convenience. The logic of the language is pretty clear. Harsh code structure allows seamlessly maintaining solutions. The developer can easily navigate the code of any complexity and improve the required component quickly. Besides, special auto-complete and auto-correction functions simplify the specialist's work.
• Cross-platform. Write once run anywhere - Java slogan for this feature. The advantage of this executing program method is the complete byte-code independence from the operating system and hardware. So, Java code can run on any device for which the JVM was implemented. This way, an application will work equally well on Windows, Linux, and other operating systems.
• Stable Stack. Working with Java, most companies use Spring, Hibernate frameworks. Thus, it is easy to replace the development team if it is needed. Many professionals in the market are experienced in these technologies.
• Reliability. The inheritance hierarchy improves the code readability and reduces the number of forced errors. The strong typing guarantees unambiguous data interpretation.
• Safety. The Java platform defines several APIs covering public infrastructure, authentication, secure transmission, and access control.
• Well-built ecosystem. During 25 years, engineers have created hundreds of frameworks, thousands of libraries, and plugins. Besides, the Java community is massive. in 2019, there were 26.4 mln Java developers. Their number will increase up to 45 mln in 2030. So any question regarding this language is already answered.

Future of Java

Java has grown to be integral to much of the modern internet and mobile app landscape, and promises to continue to be part of the information technology toolkit for some time in the future. A quarter century is an eternity in programming, so raise a `class` to Java, past, present, and future.
