The IDE provides wizards and templates to let you create Java EE, Java SE, and Java ME applications. A variety of technologies and frameworks are supported out of the box. For example, you can use wizard and templates to create applications that use the OSGi framework or the NetBeans module system as the basis of modular applications.
The language-aware NetBeans editor detects errors while you type and assists you with documentation popups and smart code completion—all with the speed and simplicity of your favorite lightweight text editor.
Building
Out of the box, the IDE provides support for the Maven and Ant build systems. In the New Project wizard, when you choose to create a new application, you can choose to create Maven-based or Ant-based applications.
You can open Maven-based applications into the IDE without an import process because the IDE reads project settings from the Maven POM file. In addition, tools are provided for importing Ant-based projects that were not created in the IDE.
The IDE includes a Maven Repository Browser, as well as graphs for analying Maven dependencies.
Debugging and Profiling
To identify and solve problems in your applications, such as deadlocks and memory leaks, the IDE provides a feature rich debugger and profiler.

Write, Run & Share Java code online using OneCompiler's Java online compiler for free. It's one of the robust, feature-rich online compilers for Java language, running the latest Java version which is Java 11. Getting started with the OneCompiler's Java editor is easy and fast. The editor shows sample boilerplate code when you choose language as Java and you can also choose hundreds of reference programs to get started. For example, if you want to write a program on Java collections choose the collections tag from reference and see hundreds of pre-written programs on collections. You can pick one of them to start your coding.
OneCompiler's Java online editor supports stdin and users can give inputs to the programs using the STDIN textbox under the I/O tab. Using Scanner class in Java program can we can read the inputs. Following is a sample program shows how to read STDIN ( A string in this case ).
OneCompiler supports Gradle for dependency management. Users can add dependencies in the build.gradle file and use them in their programs. When you add the dependencies for the first time, the first run might be a little slow as we download the dependencies but the subsequent runs will be faster. Following is a sample Gradle configuration shows how to add dependencies
Java is a very popular general-purpose programming language, it is class-based and object-oriented. Java was developed by James Gosling at Sun Microsystems ( later acquired by Oracle) the initial release of Java was in 1995. Java 11 is the latest long-term supported version (LTS). As of today, Java is the world's number one server programming language with a 12 million developer community, 5 million students studying worldwide and it's #1 choice for the cloud development.
Loops
1. If Else:
When ever you want to perform a set of operations based on a condition If-Else is used.
2. Switch:
Switch is an alternative to If-Else-If ladder and to select one among many blocks of code.
3. For:
For loop is used to iterate a set of statements based on a condition. Usually for loop is preferred when number of ierations is known in advance.

Collections
Collection is a group of objects which can be represented as a single unit. Collections are introduced to bring a unified common interface to all the objects.
Collection Framework was introduced since JDK 1.2 which is used to represent and manage Collections and it contains:
- Interfaces
- Classes
- Algorithms
Online Java Ide Geeksforgeeks
This framework also defines map interfaces and several classes in addition to Collections.
Advantages:
- High performance
- Reduces developer's effort
- Unified architecture which has common methods for all objects.

| Collection | Description |
|---|---|
| Set | Set is a collection of elements which can not contain duplicate values. Set is implemented in HashSets, LinkedHashSets, TreeSet etc |
| List | List is a ordered collection of elements which can have duplicates. Lists are classified into ArrayList, LinkedList, Vectors |
| Queue | FIFO approach, while instantiating Queue interface you can either choose LinkedList or PriorityQueue. |
| Deque | Deque(Double Ended Queue) is used to add or remove elements from both the ends of the Queue(both head and tail) |
| Map | Map contains key-values pairs which don't have any duplicates. Map is implemented in HashMap, TreeMap etc. |
