What is casting variable in java

Question

When it comes to casting objects I don't understand how it works. Please help.

Answer 1

Casting is, taking an Object of one particular type and “turning it into” another Object type. This process is called casting a variable.

If you are going to cast a variable, you’re most likely doing what’s known as a downcast.

Example:

Object obj = "This is just a regular sentence";
String objstr = (String)obj;
