Abstraction, inheritance, encapsulation, data hiding and binding, compile and run-time polymorphism, method overloading and overriding, constructor, up and down casting, super, final, jdk, jre,jvm, features of java, inner classes, multithreading( using runnable interface), interface, wrapper classes, basic collection framework(arraylist and linkedlist), string and string buffer, autoboxing and unboxing, parseInt and valueOf, static, enum, real world examples of multiple inheritance and interface, Why it is not supported in java, java current version, main method specifiers(public static void), access specifiers, packages. I was asked different questions from all these topics and was told to write code in support of my answer every time. They asked me to write two codes: a. Reverse a string ( in java), b.
