Hello, Can someone please help me how to write these functions in Java, But only using the java bit operators & (and), | (or),^ (xor), >> (right shift), >>> (right shift logical), and << (left shift)? Thank you!

### Java Utility Functions for Integer Manipulation Below are various Java static functions used for manipulating integers. Each function serves a specific purpose, from checking whether a number is odd to manipulating bits. #### 1. Checking If a Number Is Odd **Method:** ```java public static int isOdd(int x) ``` **Description:** This function returns `1` if the number is odd and `0` if it is even. - **Example Outputs:** - `isOdd(6)` returns `0`. - `isOdd(5)` returns `1`. #### 2. Division by 4 **Method:** ```java public static int DivBy4(int x) ``` **Description:** This function performs integer division by 4. - **Example Outputs:** - `DivBy4(6)` returns `1`. - `DivBy4(13)` returns `3`. - `DivBy4(3)` returns `0`. - `DivBy4(-16)` returns `-4`. #### 3. Nearest Odd Number **Method:** ```java public static int nearestOdd(int x) ``` **Description:** This function rounds up the number to the nearest odd number. - **Example Outputs:** - `nearestOdd(6)` returns `7`. - `nearestOdd(5)` returns `5`. - `nearestOdd(-4)` returns `-3`. #### 4. Flipping Parity **Method:** ```java public static int flipParity(int x) ``` **Description:** This function adds `1` to even numbers, and subtracts `1` from odd numbers. - **Example Outputs:** - `flipParity(6)` returns `7`. - `flipParity(5)` returns `4`. - `flipParity(-3)` returns `-4`. #### 5. Checking If a Number Is Negative **Method:** ```java public static int isNegative(int x) ``` **Description:** This function returns `0` if `x` is positive, and `1` if `x` is negative. - **Example Outputs:** - `isNegative(4)` returns `0`. - `isNegative(-3)` returns `1`. #### 6. Clearing Specific Bits **Method:** ```java public static

For example, say I asked you to write a function named `oneIsOne` 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: ```java public static int oneIsOne(int x){ return x | 2; } ``` Explanation: In this code snippet, a function named `oneIsOne` is defined. The function takes an integer `x` as an argument and returns an integer. The operation `x | 2` uses the bitwise OR operator to set the second least significant bit (bit one) of the integer `x` to 1. The rest of the bits in the integer remain unchanged.
