Typecasting of primitive data types in Java

Variable of smaller capacity can be assigned to another variable of bigger capacity without any explicit typecasting

int i = 10;
double d;
d = i;

Whenever a larger type is converted to a smaller type, the typecast operator has to be explicitly specified. This prevents accidental corruption of data.

double d = 10;
int i;
i = (int) d;
