What Is Java?
Java is a multiplatform programming language. It is object-oriented and network-centric. In the programming industry, Java is one of the most commonly used languages.
Java is also a computing platform. In 1995, Java was released by Sun Microsystem. The Oracle Corporation later acquired it.
Features of Java
Java allows software developers to write a code once and then run it on almost any computing platform. It was specifically created to build applications that are object-oriented.
Java’s multithreaded language allows for automatic memory management. Since it is network-centric, Java also facilitates distributed computing.
Uses for Java
Java can be used to develop many different things. It is commonly used to develop Android applications and Enterprise software. Scientific computing applications and big data analytics can also be developed with Java.
It can be used when programming certain hardware devices. Java is also used to develop server-side technologies, such as Apache, JBoss, GlassFish, and more.
Pros and Cons of Java
There are upsides and downsides to every programming language, and Java is not exempt from this. Java has many advantages. It provides detailed documentation.
Java also has a large pool of skilled developers accessible. The programming language offers a large arrangement of third-party libraries. The multithreaded environment enables tasks to work at the same time within a program.
Java can form standard programs and reusable codes. Its performance quality is fantastic. The libraries are also very simple to navigate through.
There are also disadvantages to using Java. The JIT compiler causes programs to run relatively slower. Java also has high memory and processing requirements, which often increases the hardware costs.
There is no support provided for low-level programming constructs, such as pointers. Java also offers no control over the garbage collection because there are no functions like delete() or free().
The compilation process for Java involves interpreting and compiling. The programming language translates source code into bytecodes and is executed by Java Virtual Machine or JVM.
Compiling vs Interpreting
Java is a compiled language, meaning that it checks the code of the whole project and also optimizes and converts the source code into bytecode. This bytecode can be read later on by JVM. This allows most of the syntactical errors to be found, and the developers will be alerted at the time of compilation.
While this is heavily beneficial, it will not prevent logic errors from happening in the programming. However, it does offer an opportunity to fix any syntactical errors immediately.
Compiled languages also often resolve the problem of an intellectual property’s security. While Java will not innately protect a program’s code, there are ways to protect its output.
With that being said, larger projects will require a ton of organization and discipline to build and maintain them using an interpreted language. There are also no great options to make the code inaccessible and executable, which can cause issues with the security of the intellectual property.
Static vs Dynamic
Static typing, which is used in Java, locks variables into a certain type. If there are mismatches within the code, a program will be unable to execute the code until the problem is fixed. This makes good coding habits a necessity and requires that intentions align throughout the entire project.
There is a disadvantage to this, which is that prototyping becomes more difficult. Rapid development is often slowed down in the beginning stages of the creation of a product.
The disadvantage to this is the unpredictability of a variable’s contents at any specific time. If a variable is given the wrong content, it will not be discovered until the code is actually executed and the outcome is incorrect.
Object-Oriented Programming and Functional Programming
Java’s solution to functional programming was lambas, which were released in Java 8. This impressive method of filtering and manipulating data collections is quite effective. However, it is restricted solely to data manipulation and goes no further than that.
Libraries and Frameworks
Proper libraries are absolutely crucial for a language, regardless of its abilities. If a language has proper established support and braintrust, then it is able to trump any other language, even those that are well-constructed.
Integrated Development Environments and Test Tools
Similar to libraries, integrated development environments, or IDEs, can cause a language to be quite successful or aid in its demise. A proper IDE enables a developer to make their way through the codebase quickly and efficiently.
Java also has many test tools, most of which are intertwined with its IDEs, such as JUnit. This makes for fantastic test development. Results from the test are able to be reviewed in a specific window from an IDE that the developer desires, allowing them to go through each individual unit test and debug along the way.
Java is multithreaded and allows its code to be compiled at once, which provides an execution that is faster. However, it is carried out on the server-side, which can slow down user interaction.
Java is often preferred for developing Android applications, Enterprise software, and server-side technologies. With APIs and third-party libraries being readily available, Java has a bit of an advantage.
Developers should pick the language that fits their development needs instead of focusing on which is the better option overall.
