What is Java?
Java is a high-level object-oriented programming language that follows the principle of WORA (Write Once Run Anywhere). It means that you can run the Java Program multiple times on all java supported platforms after it has been compiled. There is no need for recompiling the code to run it every time. Java was originally developed by Sun Microsystems.
Benefits of Using Java
A community of java developers and architects constantly refine, test, and extend Java to simplify it for users and make coding with Java more efficient. Java has constantly evolved over the years to enable high-performance applications on a range of computing platforms. The applications are also available across heterogeneous environments and that is the reason why businesses are able to improve end-user productivity, provide more services, and enable better collaboration. Java also reduces the cost of ownership for enterprise applications and consumer applications.
Java is widely used by developers because of the following benefits and features:
- The simplicity of use - Java is an easy to learn programming language and the syntax is similar to that of C and C++.
- Object-oriented programming - Java is called an object-oriented programming language as it based on objects that imitate real-world scenarios. It also supports the four pillars of an object-oriented language, i.e., Inheritance, Polymorphism, Abstraction, and Encapsulation.
- Platform Independence - Java has its own virtual machine. It converts the codes into bytecode which can easily run in any java supported platform. Hence, java is known to be platform-independent.
- Secured programming language - Java has its own box responsible for handing its execution. It does not support pointers and multiple inheritances that cause ambiguity or lead programs to crash. Due to these reasons, Java is much more secured than other programming languages.
- Efficiency - Java uses JIT (Just In Time) compiler that utilises the best of the compiler and the interpreter. This feature makes Java more efficient than other programming languages.
- Multi-threaded - Java allows multiple tasks to execute concurrently and that too without occupying much memory. This is possible because Java supports thread.
What are JDK, JRE, and JVM
JVM stands for Java Virtual Machine.
- It is a virtual machine that performs all Java executions
- It manages the garbage collector, heap memory, etc.
JRE is short for Java Runtime Environment.
- It runs the precompiled java programs
- JRE stores all the files and libraries that are used to facilitate the running of codes in Java
JDK stands for Java Development Toolkit.
- This software enables the development of Java Applications
- It is basically JRE plus development tools
Variables in Java
Variable is the name of the memory location where the data is stored. There are a few things that you would need to keep in mind while working with variables in Java.
- A variable name should begin with a letter, $, or an underscore symbol(_)
- The first letter in the name of the variable can be followed by any combination of digits and letters
- Variable name should not be the same as a keyword because the keywords are reserved for special purposes
- Variable names are case sensitive
The three types of variables in Java are:
- Local Variables
- Instance Variables
- Static Variables
Data Types in Java
There are different types of data that one deals with in real life. To process them we need different types of containers or data types as storage. In java, there are 8 primitive data types:
- byte – size is 1 byte and by default, it holds 0
- int – size is 4 byte and by default, it holds 0
- short – size is 2 byte and by default, it holds 0
- long – size is 8 byte and by default it holds 0L
- char – size is 2 byte and by default, it holds ‘\u0000’
- boolean – size is 1 bit and by default it holds false
- float – size is 4 byte and by default it holds 0.0f
- double – size is 8 byte and by default, it holds 0.0d
There are also some non-primitive data types like arrays, classes such as String etc.
Operators in Java
The different types of Operators in Java:
- Unary Operators
- Arithmetic Operators
- Shift Operators
- Relational Operators
- Bitwise Operators
- Logical Operators
- Assignment Operators
- Ternary Operators
