hexadecimal matches with modulo 8 word sizes, such as 8, 16, 32, and 64 bits. You signify a hexadecimal constant with a leading zero-x, (0x or 0X).
The range of a hexadecimal digit is 0 to 15, so A through F (or a through f ) are substituted for 10 through 15.
An integer literal can always be assigned to a long variable. An integer can also be assigned to a char as long as it is within range.
public class Main{
public static void main(String[] argv){
int f = 0XFFFFF;
System.out.println(f);//1048575
}
}
