Reverse a string using StringBuilder or StringBuffer
Find second highest number by sorting the array and accessing the second last element
String is immutable while StringBuffer is mutable
HashMap stores key-value pairs while HashSet stores only keys
Instance variables are declared inside a class while local variables are declared inside a method
Primitive data types are int, float, double, etc. while non-primitive data types are arrays, classes, etc.
Overloading is having multiple methods with the same name but different parameters while overriding is implementing a method in a subclass that is already present in the superclass
Framework is a set of guidelines, libraries, and tools used to develop software applications
