How do I change nibbles in Java?

How do I change nibbles in Java?

The two nibbles are (0110) and (0100). If we swap the two nibbles, we get 01000110 which is 70 in decimal. To swap the nibbles, we can use bitwise &, bitwise ” operators.

How do you set nibbles in integer?

how to replace given nibbles with another set of nibbles in an…

1. Clear the bits we’re going to replace from a . like a = 0x02045070.
2. Create the mask from the short b like mask = 0xa0b00c0d.
3. bitwise OR them to get the result. result = a| mask i.e result = 0xa2b45c7d hence nibbles replaced.

How can I swap two numbers using bitwise Operators?

Java Program to Swap Two Numbers Using Bitwise Operator

1. Find the binary equivalent of given variables, say X and Y.
2. Find X^Y and store it in x, i.e. X = X ^ Y.
3. Again, find X^Y and store it in Y, i.e. Y = X ^ Y.
4. Find X^Y and store it in X, i.e. X = X ^ Y.
5. The numbers are swapped.

What does 0x55 mean?

We know that 0xaa and 0x55 are hexa-decimal representation . Moreover each character in hexadecimal is represent using 4bits. so , 0xaa is equivalent to 1010 1010 (since, a = 1010 in binary) and 0x55 is equivalent to 0101 0101 (since, 5 = 0101 in binary)

How do you change a nibble?

To swap the nibbles, we can use bitwise &, bitwise ” operators. A byte can be represented using a unsigned char in C as size of char is 1 byte in a typical C compiler.

What does Swap nibbles mean?

A nibble is a four-bit aggregation, or half an octet. Given a byte, swap the two nibbles in it. For example 100 is be represented as 01100100 in a byte (or 8 bits). The two nibbles are (0110) and (0100). If we swap the two nibbles, we get 01000110 which is 70 in decimal.

What is 0x10?

0x means the number is hexadecimal, or base 16. 0x10 is 16.

How to swap the nibbles in C program?

Let see the C program to swap the nibbles, As we know binary of 100 is 01100100. To swap the nibble we split the operation in two parts, in first part we get last 4 bits and in second part we get first 4 bit of a byte.

How to swap the nibbles of a binary number?

The code to swap the nibbles is as given below: “x & 0x0F” represents the last four digits of the binary number. Here the last four digits of “00010000” are “00000000 “.”<<” shifts the last four digits to the left and makes the current last four digits to zero i.e, “00000000” in this case.

How many bits are there in a nibble?

A nibble is a four-bit aggregation, or half an octet. There are two nibbles in a byte. Given a byte, swap the two nibbles in it. For example 100 is be represented as 01100100 in a byte (or 8 bits).

How many nibbles are there in an octet?

A nibble is a four-bit aggregation, or half an octet. There are two nibbles in a byte. Given a byte, swap the two nibbles in it.
