casting in java

In simple language casting means changing one type of data type into another example changing double data type into int.
ie.

public class mk{
public static void main(String[] agrs){
double price = 55;
double finalPrice = 16.55;
System.out.println(finalPrice);
// our result will be 71.55 which is known as Implicit casting
// but now if we change our double type data type into int data type;
ie.
int p = 55;
int fp = p + (int)16.55;
System.out.println(fp);
//our result will be 71 only which is known as Explicit casting.
