public static int clearBits(int x). This function sets all bits of x except bits 4 through 7 to 0. It leaves bits 4-7 unchanged. It returns 0 on 3, 128 on 128, 128 on 1668, and 240 on -3. public static int setBits(int x). Set bits 4 through 7 of x to 0110. All other bits remain unchanged. It returns 99 on 3, 96 on 128, 1636 on 1668, and -147 on -3.

Question

Hi there. How can I write these functions in java only using the java bit operators & (and), | (or),^ (xor), >> (right shift), >>> (right shift logical), and << (left shift)? I need to learn how to write them without using a loop for if statements.

It returns 0 on 3, 128 on 128, 128 on 1668, and 240 on -3. public static int setBits(int x). Set bits 4 through 7 of x to 0110. All other bits remain unchanged. It returns 99 on 3, 96 on 128, 1636 on 1668, and -147 on -3.

For example, say I asked you to write a function named onelsOne that sets bit one of an integer to one while leaving the rest of the bits unchanged. My code for that function would look like this: public static int oneIsOne(int x){ return x | 2; }
