Advantages of Java Programming Language – Java is a programming language and high-level computing platform developed by Sun Microsystems in 1995. Since then, the language has been updated regularly with Java SE 8.0 the latest version, released in March 2014.
Based on the advantages of Java, it has gained great popularity and various configurations have been created to meet different types of platforms, including Java SE for Macintosh, Windows, UNIX, Java ME for mobile applications, and Java EE for enterprise applications.
With the increasing importance of web-based and mobile applications, Java is now the basis for most web applications and is considered useful for scripting, web-based content, enterprise software, games, and mobile applications.
Java is a relatively high-level language. It offers a variety of out-of-the-box features that make it easier for today’s developers to learn and focus on real business implementation rather than worrying about managing the infrastructure at the system level.

Some of the advantages of the Java programming language are:
Platform Independence
Platform Independence: Java is platform independent, which means that if a program is written and compiled in Java on any platform (underlying hardware and software), it can run on any other platform of similar capabilities subject to available hardware (power computing power, memory, and disk space) and software (JRE installed). This is achieved by virtue of the software component called the Java Virtual Machine which is an abstract computing machine, when I say abstract I mean it can have many implementations. Oracle provides one such implementation.
Automatic storage management
Automatic storage management: This is done using a garbage collector, which avoids the security issues of explicit deallocations. This means that a programmer does not need to call the destructor (as in C/C++) to explicitly allocate memory used by structures or objects. In Java, when an object is no longer referenced, it can be reclaimed by the garbage collector. The scheduler cannot force the garbage collection event, the JVM operates on an as-needed basis. Java also provides facilities for objects to do some cleanup work (if necessary), such as freeing up connections and other system resources before they are garbage collected. Java with the help of JVM also downloads classes if they are no longer needed at runtime.

Avoid unsafe constructs
Avoid unsafe constructs: Java arrays are accessed after explicitly doing an index check on array boundaries. An ArrayIndexOutOfBoundexception exception is thrown if the program tries to access an index that is not within the range of the array. This helps in running the program correctly otherwise imagine a scenario where the language does not check the array index and returns a value stored in the memory location but the memory location is not within the array bounds. This can cast a big doubt on the accuracy of your program.
Type Safety
Type Safety: Java is a safe programming language due to its typed and strongly typed nature. Statically typed means that every variable is declared and has a type and the type is known at compile time. Strongly typed means that a variable can only be assigned a set of values compatible with the variable’s type. It also helps to identify most compile-time errors and clearly distinguish them from runtime errors.
Multi-threading support
Multi-threading support: Java encapsulates the underlying system thread infrastructure and provides optimal and easy support for multithreading. There is no explicit need to register monitor code to acquire locks on objects. Java also makes it easy to create multiple threads and perform independent tasks with the help of Chaining Sets.
