Examples

int j = 2;
int k = ~j; // k = -3; j = 2;
boolean z = x != y;
//
byte x = 5;
byte z = -x; // error
byte y = (byte) -x; // correct
short x = 200;
short y = 400;
short z = x + y ; // error
short z = (short) (x + y); // correct
//
// The casting is necessary or an integer will be assigned to pi
final float pi = (float) 22 / 7; 
//
