why is typecasting done in java?

Answer 1

Assigning a value of one type to a variable of another type is known as Type Casting.

If I ask for the user a input for a item quantity and I get it as an integer:

int qtt = 2;

Imagine I want get this quantity as a float 2.00, so I need to Type Cast this int into float:

float newQtt = (float)qtt;
