Type casting in Java is the process of converting one data type into another.
Type casting can be done implicitly or explicitly.

Type casting is useful when we want to use a variable of one data type in an expression or assignment ...
Method overloading is when multiple methods have the same name but different parameters.
Method overloading allows for more flexibility in method calls.
The methods must have different parameters, such as different data types or different numbers of parameters.
Example: public void print(int num) and public void print(String str)
Overloading constructors is also common in Java.
Method overloading allows creating multiple methods with the same name but different arguments.
Method signature must differ in number, type, or order of parameters
Return type can be different but not the only difference
Example: public void print(int num), public void print(String str), public void print(int[] arr)
Overloading improves code readability and reusability
