![### 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](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fd104ea5e-59f4-47a3-a0d3-8c9f1ad3b57c%2Ffdf51273-5beb-4663-94a0-ae78d18ce07e%2Fk87ljf_processed.png&w=3840&q=75)

- `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.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fd104ea5e-59f4-47a3-a0d3-8c9f1ad3b57c%2Ffdf51273-5beb-4663-94a0-ae78d18ce07e%2Fmwpfu0l_processed.png&w=3840&q=75)
