typecast operator - What is the Use of TypeCasting in java -

we can achieve output in 2 ways 1 typecasting , 1 without typecasting

a a=new b() // without typecaste  a  = (a)a// typecaste 

in both ways same output.so, use of typecasting

let's assume have list of animals. , have tigers , lions in it.

arraylist<animal> animals = new arraylist<>(); //add tigers , lions //sort tigers @ beggining of list tiger t = (tiger)animals.get(0); 

without casting type missmatch @ compile time. cast risk classcastexception can easy caught try-catch

it's example of proper use of class casting in java.
