Both of them, even after being programming languages, do not have a lot of similarities between them. It is a C like syntax which is put to use in both the languages. Apart from that, both are widely used in Web Applications on the client-side.
However, only these are the kind of similarities they possess and thus, it can be inferred that they only have a few similarities and more of differences between them.
What is Java?
It is a general-purpose high-level programming language, that is class-based and designed to have as few implementation dependencies as possible. The former name of Java was Oak.
Java is a language for programming that is majorly object-oriented and its applications can be easily run in any Virtual Machine or browser.
Since the objects are class-based, they cannot be created without forming classes. This is also the reason why it takes up a large amount of memory as compared to other programming languages.
It is a great software in the sense that it allows the application developers to write once, run anywhere. The Java syntax is similar to C and C++, however, the difference is that the lower-level facilities in Java are fewer as compared to both of them.
The original development of Java was done by James Gosling at Sun Microsystems and it was in 1995 that it was released as a core component of the Java platform of Sun Microsystems.
Java is known to be stricter than C++ and this means that the variables and functions need to be explicitly defined. This also signifies that the Java Source Code can produce errors or ‘exceptions’ pretty much more easily than other programming languages.
The Java programs cannot directly be run by an operating system like Windows executables or Macintosh applications. They are interpreted by a Java Virtual Machine which can run on multiple platforms.
However, the JVM must be installed to make sure that Java programs can be run.
Both the languages have quite a lot of differences between them, mainly of a technical nature, and to have an overview of them is not something which would pose a lot of problems.
