Java is simple, object-oriented, and platform-independent. It is widely used in real-time projects like web apps, Android apps, and enterprise applications. It also has strong community support and frameworks like Spring Boot, which makes development easier. Java is a high-level, object-oriented programming language developed by Sun Microsystems. It is platform-independent because of the JVM, and it is widely used for secure and scalable applications. OOPs has 4 main concepts: Encapsulation → Binding data and methods in one class. Abstraction → Hiding implementation, showing only details. Inheritance → One class can use properties of another. Polymorphism → Same function in different ways (overloading & overriding). Exception handling is used to handle runtime errors in Java. It avoids abnormal program termination and allows smooth execution. It is done using try, catch, finally, throw, and throws.
