What is the use of type 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.

Casting processes involve the use of molten material, usually metal. This molten material is then poured into a mould cavity that takes the form of the finished part. The molten material then cools, with heat generally being extracted via the mould, until it solidifies into the desired shape.
