**What does 0xff mean in Java?**

The hex literal 0xFF is an equal int(255). Java represents int as 32 bits. It look like this in binary: 00000000 00000000 00000000 11111111. When you do a bit wise AND with this value(255) on any number, it is going to mask(make ZEROs) all but the lowest 8 bits of the number (will be as-is).

### Is there a difference between 0xff and 0xff?

Well, 0xff is the hexadecimal number FF which has a integer value of 255. And the binary representation of FF is 00000000000000000000000011111111 (under the 32-bit integer). In a nutshell, “& 0xff” effectively masks the variable so it leaves only the value in the last 8 bits, and ignores all the rest of the bits.

**What is 0xff byte?**

The signed byte 0xff represents -1 because its most significant bit is 1 (so therefore it represents a negative value) and its value is -128 + 64 + 32 + 16 + 8 + 4 + 2 + 1 = -1 .

## How can I convert Hex string into decimal number?

**What does the ‘0x’ mean in hex numbers?**

*nix (UNIX and related) shells, and likewise the C programming language, which was designed for UNIX (and the syntactical descendants of C [2]) use the prefix 0x for numeric constants represented in hex: It’s a prefix to indicate the number is in hexadecimal rather than in some other base.

### How do you calculate hexadecimal?

Here’s how to calculate it, just as you would in long division: Multiply your last answer by the divisor. In our example, 1 x 256 = 256. (In other words, the 1 in our hexadecimal number represents 256 in base 10). Subtract your answer from the dividend.
