What is casting in Java?
Type casting is a way of converting data from one data type to another data type. This process of data conversion is also known as type conversion or type coercion. In Java, we can cast both reference and primitive data types. By using casting, data can not be changed but only the data type is changed.

Why do I get an ArithmeticException when casting long numbers?
In other words, if you try to cast a long number that cannot be represented as int (eg any number strictly above 2 147 483 647) it will throw an ArithmeticException. If you do the same with a simple cast, your resulting int value will be wrong.
How many INTs can fit in a long type in Java?
This means that any number of int type can easily fit into a long type. In Java, when working with primitives, the conversion from a narrower type to a wider type is automatic.
What is casting in C programming language?
In typing casting, a data type is converted into another data type by the programmer using the casting operator during the program design. In typing casting, the destination data type may be smaller than the source data type when converting the data type to another data type, that’s why it is also called narrowing conversion.
