Each package contains a set of related interfacesclasses, and exceptions. Refer to the separate platforms for a description of the packages available. Execution System Main articles: Java software platform and Java virtual machine One design goal of Java is portability, which means that programs written for the Java platform must run similarly on any combination of hardware and operating system with adequate runtime support.

This is achieved by compiling the Java language code to an intermediate representation called Java bytecodeinstead of directly to architecture-specific machine code.

Java bytecode instructions are analogous to machine code, but they are intended to be executed by a virtual machine VM written specifically for the host hardware.


End users commonly use a Java Runtime Environment JRE installed on their own machine for standalone Java applications, or in a web browser for Java applets. Standard libraries provide a generic way to access host-specific features such as graphics, threadingand networking.

The use of universal bytecode makes porting simple. However, the overhead of interpreting bytecode into machine instructions made interpreted programs almost always run more slowly than native executables. Just-in-time JIT compilers that compile bytecodes to machine code during runtime were introduced from an early stage.

Java itself is platform-independent and is adapted to the particular platform it is to run on by a Java virtual machine for it, which translates the Java bytecode into the platform's machine language.

Non-JVM Some platforms offer direct hardware support for Java; there are microcontrollers that can run Java bytecode in hardware instead of a software Java virtual machine, [52] and some ARM based processors could have hardware support for executing Java bytecode through their Jazelle option, though support has mostly been dropped in current implementations of ARM.

Automatic memory management Java uses an automatic garbage collector to manage memory in the object lifecycle. The programmer determines when objects are created, and the Java runtime is responsible for recovering the memory once objects are no longer in use.

Once no references to an object remain, the unreachable memory becomes eligible to be freed automatically by the garbage collector. Something similar to a memory leak may still occur if a programmer's code holds a reference to an object that is no longer needed, typically when objects that are no longer needed are stored in containers that are still in use.

If methods for a nonexistent object are called, a "null pointer exception" is thrown. In some languages, memory for the creation of objects is implicitly allocated on the stack or explicitly allocated and deallocated from the heap.

In the latter case, the responsibility of managing memory resides with the programmer. If the program does not deallocate an object, a memory leak occurs. If the program attempts to access or deallocate memory that has already been deallocated, the result is undefined and difficult to predict, and the program is likely to become unstable or crash.

This can be partially remedied by the use of smart pointersbut these add overhead and complexity.

I think Netbeans is the betters tools to programming and understand Android, but nbandroid MUST BE UPGRATED! As example, now is impossible deploy google maps with the new Android SDK (25 and on) I forgot, I hate gradle and love ant so NbAndroid for Netbeans 8,0 was perfect for this! Even with your pleasant with Netbeans IDE I’m recommended to use eclipse IDE or android studio to develop android app these are especially for developing android apps development, Netbeans IDE also used for developing android apps but this Netbeans IDE is used mostly for developing java officially supports and recommends the Android studio and Eclipse IDE for developing .

Note that garbage collection does not prevent "logical" memory leaks, i. Garbage collection may happen at any time. Ideally, it will occur when a program is idle. It is guaranteed to be triggered if there is insufficient free memory on the heap to allocate a new object; this can cause a program to stall momentarily.

Explicit memory management is not possible in Java. This allows the garbage collector to relocate referenced objects and ensures type safety and security.

This was a conscious decision by Java's designers for performance reasons. Java contains multiple types of garbage collectors. By default, HotSpot uses the parallel scavenge garbage collector.

There are three different styles of comments: The Javadoc style of commenting allows the user to run the Javadoc executable to create documentation for the program and can be read by some integrated development environments IDEs such as Eclipse to allow developers to access documentation within the IDE.

It must first be compiled into bytecode, using a Java compilerproducing a file named HelloWorldApp. Only then can it be executed, or "launched".

The Java source file may only contain one public class, but it can contain multiple classes with other than public access modifier and any number of public inner classes. When the source file contains multiple classes, make one class "public" and name the source file with that public class name.

A class that is not declared public may be stored in any. The compiler will generate a class file for each class defined in the source file. The name of the class file is the name of the class, with. The keyword public denotes that a method can be called from code in other classes, or that a class may be used by classes outside the class hierarchy.For coders go and want to continue coding Android is a good platform to use, we look at the 10 Android Apps and IDE's for Java Coders and Programmers.

Please help me, If you have any idea about that so please share with me.

Netbeans will always be a general purpose IDE (with some focus on Java EE), but Android Studio is custom built for Android development. Any efficiency you might gain by staying with Netbeans, which I think boils down to just keyboard shortcuts, you'll lose by missing out on first class Android support.

Coding on a Android Tablet or Smartphone. Recently at IDRsolutions my collegues have spent a lot of time traveling to different conferences such as Oracle Code One and of the complaints my colleagues have is the amount of luggage they have to carry, especially when they still want to work on code for our Java PDF Library, Java Image Library and Online Document Viewer.
