// What is difference between String, StringBuffer and StringBuilder?
// 1. Mutability Difference:

// String is immutable, if you try to alter their values, another object gets created, whereas StringBuffer and StringBuilder are mutable so they can change their values.

// 2. Thread-Safety Difference:

// The difference between StringBuffer and StringBuilder is that StringBuffer is thread-safe. So when the application needs to be run only in a single thread then it is better to use StringBuilder. StringBuilder is more efficient than StringBuffer.

        //     s += "+Hello";
