Understanding String Concatenation with Operator Overloading in Java

This article explores string concatenation in Java using operator overloading. We will demonstrate how the '+' operator can combine strings with integers, such as in the examples of "wind" + "ow" leading to "window", and the numeric concatenation example with System.out.println(5 + 6 + "hello"). You'll learn how Java handles different data types during concatenation and how to expect outputs like "11hello" or "hello56". Our examples illustrate practical applications, enhancing your understanding of this essential concept in Java programming.
