Java Development Services

Java is a high-level, object-oriented programming language known for its platform independence and versatility. It is used to build robust and scalable software applications and provides a wide range of libraries and frameworks for streamlined development.

Java brings multiple advantages to software development. Firstly, it provides platform independence, allowing applications to run seamlessly on different operating systems. Secondly, Java's object-oriented nature promotes modular and reusable code, enhancing productivity and maintainability. Thirdly, its extensive libraries and frameworks simplify development tasks. Additionally, Java's robustness ensures reliable and secure applications. Lastly, its strong community support and vast talent pool make it a popular choice for software development, ensuring ongoing updates and improvements.

Java is a versatile programming language with extensive applications. It is primarily employed in the development of enterprise-level software like CRM systems, HRMS, and financial software. Java is also the preferred choice for Android app development, powering mobile applications on a global scale. Furthermore, it finds utility in web development, scientific research, gaming, and embedded systems, showcasing its versatility across various domains.

While Java has many advantages, it also has some drawbacks. Firstly, Java's performance can be slower compared to other programming languages. Secondly, the learning curve for Java can be steep, requiring developers to invest time in mastering the language. Additionally, Java's memory consumption can be higher due to its automatic garbage collection, potentially affecting application efficiency.

Opting for Java Full Stack Development offers numerous advantages. Firstly, it equips you with a comprehensive skill set, enabling you to work seamlessly across both front-end and back-end technologies. Secondly, Java's vast ecosystem provides a wide range of libraries, frameworks, and tools for efficient development. Additionally, Java's platform independence ensures compatibility across different environments. Lastly, with Java Full Stack Development, you have the flexibility to build end-to-end applications, making you a valuable asset in the software development industry.

Text blocks are nothing but multiline strings. If we have to write a string as if it was a normal string with a simple json string then it will be very difficult to read as we have to add escape characters in between actual string but with text blocks in java 15 you can write multiple strings to represent a json as below:

Text blocks start with three double quote “”” and close with the same “””.

In java 16, you can bind a variable to the expression on instanceof which means lest say for example in equals method :

Here object instanceof XClass that : here “that” is the name of a variable that gets assigned to a cast down XClass for objects. So, it already has the type of XClass and if instanceof resolves to a true then that gets bound to that expression. Also that variable can be referred inside of the block in variable scope. If(ob instanceof String st && st.length() > 19 ) here s is in scope.

Records are a feature introduced in Java 16. Records are defined as "classes that serve as transparent carriers for immutable data." The primary application of records is to return numerous values. We can simply create data composites to return numerous items, allowing us to design clean, single-purpose classes with a defined set of component values.

As previously said, we established a Record with min and max integer components. We obtain a standard set of implementations when we use this Record:

• Canonical Constructor with Accessor methods (min() and max()) for each component
• Object equals and hashcode methods ()

Before Java 16, you couldn't prevent an interface from being extended by another interface, and you had to define a class as final to prevent it from being extended by another class.

You can now prevent an interface from being extended by other interfaces by creating a rule that only certain interfaces are permitted to extend it.

You may now design an interface and restrict which classes are permitted to implement it. It is not permitted to be implemented by any other classes. You can now limit a class from being extended (like you could with final), but you can also enable select classes to extend it.

When code in a programme attempts to dereference a null reference, the JVM throws a NullPointerException. The JVM defines the variable, I mean in their source code with a null-detail message in the NullPointerException from the version Java SE 14. It considerably increases programme comprehension by linking a dynamic exception with static programme code more explicitly.

For ex:

Java 16 made significant changes to the way the language functions.

Records: Records are all about representing data in Java code as data rather than as random classes.

Pattern Matching: Record patterns where we might be able to pattern match our records and bind the component values to new variables right away

ZGC: Garbage collector enhancements: Concurrent Thread-Stack Processing

Socket channels supporting Unix domains: It enhanced support to the server-socket channel APIs in the java.nio.channels package

Vector APi : Enhancement to incubator module with initial iterations jdk.incubator.vector, to express vector computations

In java 10, type inference got introduced .Instead of writing a type Int, String or any other datatype, you can just write with “var” and then the correct type will be inferred by the java compiler. For ex: var str = “mano” , here compiler will infer String type to variable str. But in this you will not be able to declare only without assignment.

Shenandoah GC got introduced with low pause and concurrent compacting GC. Also ZGC improvements were there with concurrent class unloading.

Expression switch got introduced in Java 14 where swich is no more a statement instead it is an expression where the case statements can be written as comma separated instead of semicolon and to produce the values, arrow(->) is used like below example
