For this assignment, please create a java class called BitFiddling Practice. It should have four methods. 1. public static int getFourthLeastSignificantBit(int x) This should return the value of the fourth least significant bit of x (which will have value either 0 or 1). 2. public static int getMostSignificantBit(int x) This should return the value of the most significant bit of x (which will have value either 0 or 1). 3. public static int setFourthLeastSignificantBitToOne(int x) This should return x except that if its fourth least significant bit was not already 1, it should now be changed to 1. The other bits should stay the same. 4. public static int getThreeLeast SignificantBits(int x) This should return a number between 0 and 7 representing the three least significant bits from x
