Java is a relatively high level language. It offers several ready-to-use resources, which facilitates learning for today's developers and focuses on the actual implementation of the business, instead of worrying about the management of the infrastructure at the system level. Few of the advantages of the Java programming language are:
Platform independence • java is independent of the platform, which means that if a program is written and compiled in Java on any platform (underlying hardware and software), it can be run on any other platform of similar capabilities subject to available hardware (power of computing, memory and disk space) and software (installed JRE). • This is achieved by the virtue of the software component called Java Virtual Machine, which is an abstract computing machine, when I say abstract, I mean it can have many implementations. Oracle provides one of these implementations.
Automatic Storage Management • This is done using a garbage collector, which avoids the security problems of explicit deallocations. This means that a programmer does not need to call the destructor (as in C / C ++) to explicitly allocate the memory used by the structures or objects. In Java, when an object is no longer referenced, it can be retrieved by the garbage collector. • java training in chennai • The programmer can not force the garbage collection event, the JVM operates according to the need. Java also provides resources for objects to perform some cleanup work (if necessary), how to release connections and other system resources before they are collected as garbage. • Java with the help of JVM also downloads classes if they are no longer needed in the execution.
Avoid unsafe constructions • Java arrays are accessed after explicitly making an index check in the boundaries of the array. An ArrayIndexOutOfBoundexception is thrown in the event that the program tries to access an index that is not within the range of the array. • This helps in the execution of the program correctly, otherwise, imagine a scenario in which the language does not check the index of the array and returns a value stored in the location of the memory, but the location of the memory is not within the boundaries of the matrix. This can pose a great doubt about the accuracy of your program. • java training in bangalore
An explicit declaration order is not necessary • It does not require that the types (Classes or Interfaces) or their members (fields and methods) be declared before their use. • It only becomes significant when we declare local variables, local classes and the order of initializers of fields in a class or interface. • java online training • All other variables are automatically initialized to a predetermined value, the Java programming language does not automatically initialize the local variables.
Type safety • Java is a safe programming language due to its typified nature and strongly typed. Statically typed means that each variable is declared and has a type and the type is known at the time of compilation. • Strongly typed means that a variable can only be assigned to a set of values compatible with the variable type. This also helps identify most errors at compile time and clearly distinguishes them from runtime errors. java training in pune
Multi-threading support • Java encapsulates the thread infrastructure of the underlying system and offers optimal and easy support for multi-threading. • There is no explicit need to record a monitor code to acquire locks on objects. • Java also facilitates the creation of multiple chaining and the execution of independent tasks with the help of Chaining Sets. • Exceptions Manipulation Support • Java has defined an Exceptions Hierarchy and has an optimal support for Exception Handling. This offers a lot of robustness and helps developers deal with compile-time exceptions without failures and write a defensive program.
