Disadvantages of the Java language

Some technical aspects of the Java language have slowed down in both the development process and the coding system. Without both templates, parametric polymorphism, or a built-in preprocessor, it is impossible to produce efficient, specialized versions of the same underlying method from within Java itself. Other drawbacks of Java are: follows:

Not separating levels of departments within the Java language.
No prerequisites that guarantee technical support for users of the Java language.
Lack of support in Java for writing generic data structures and methods.
Lack of diversity in the Java language.
Security, because code executed on users' computers can in some cases be exploited for malicious purposes, and this is one of the reasons why some people choose to disable JavaScript.
Depending on the end user, sometimes JavaScript will be interpreted differently by different browsers while server-side scripts will always produce the same output, while client-side scripts can be unpredictable.

History of the origin of the Java language

It was the beginning of the emergence of both the Internet and the World Wide Web in the year 1996 AD, and at the same time Microsoft was working on issuing its first operating programs, Windows 95, which was not even equipped with an Internet browser, and at that time the Java language was not associated in any way with the Internet, and as a result, Java programmers showed More attention to web software than other competing language programmers, which is a constant challenge, and over the years Java has released many of its versions, which have been given sub-titles such as (JDK 1.2, Java 2, SDK, Java 5, Java 7).
