Little Sugar 1 ( Java)

So often i come across something cool , but important so i thought using blogging about them would be nice idea , so here is my Little Sugar 1

when converting from 1 type to another , sign extension is performed if the source data is signed
eg

byte b = 0xff;
char c = (char) b

if the type is char , no sign conversion is peformed .

if converting from byte to char if no sign conversion is required than bitwise AND with 0xff is nice idea.


char c = (char) b & 0xff
