By understanding type conversion, casting, and type promotion, you'll be better equipped to manage data types and handle conversions between them in your Java programs.

Explicit conversion is called casting. Converting larger data type to smaller, int to byte. eg: int a = 10; byte b= 10; b= (byte)a; While casting if the value which need to be converted is greater ...

However, short is explicitly compatible to int, because the assignment shortVariable = (short)intVariable; is possible. Here we must mark compatibility by casting, also known as type conversion.

Take your coding to the next level by learning advanced programming with generics. Here's how to use generic methods with type inference, type parameters, and wildcards in your Java programs.

Other String to long conversion approaches There are other, less technically correct ways to convert a text String to a long primitive type in Java. Those String to long conversion approaches include: ...
