1. question about 128 bit number    stackoverflow.com

can i represent 128 bit number in java? or in c++?

2. How the bits are stored in C++, How to represent similar functionality in Java    stackoverflow.com

I have in C++:

typedef struct _msk {
char    abc[4];
//some more variables
}

_msk mr;

if (some condition >= 70) {
   mr.abc[0] |= 0xC0;   //C0 in binary 11000000
  ...

3. How to follow C++ bit storage in Java?    stackoverflow.com

if I have in c++:

char abc[4];

abc[0] = 0xC0; //11000000 in binary

abc[1] = 0x20; //00100000 in binary

abc[2] = 0x44; //01000100 in binary

abc[3] = 0x20; //00100000 in binary

1. C++ - static char **gprs; In Java - private static String[] gprs; OR private static Byte[] gprs;
2. C++ - static ...

5. Is there a more elegant way of doing these bitwise operations?    stackoverflow.com

I built this program that does some bitwise operations on three numbers: 2, 4 and 20:

public static void main(String[] args) {
    int mask = 63;
    ...
