![### Converting a While Loop to a For Loop
In this section, we will learn how to rewrite a `while` loop using a `for` loop. Consider the following code snippet:
```java
long prod = 5;
int x = 3;
boolean valid = true;
while(x <= 22 && valid) {
prod = prod * prod;
x = x + 5;
}
```
#### Explanation of the Given Code
1. **Initialization:**
- A `long` variable `prod` is initialized to `5`.
- An `int` variable `x` is initialized to `3`.
- A `boolean` variable `valid` is set to `true`.
2. **While Loop Condition:**
The loop will continue to execute as long as both conditions are true:
- `x` is less than or equal to `22`.
- `valid` is `true`.
3. **Loop Body:**
- `prod` is multiplied by itself and the result is stored back in `prod`.
- `x` is incremented by `5`.
#### Conversion to a For Loop
To rewrite this `while` loop using a `for` loop, we need to incorporate the initialization, condition, and increment/decrement steps in the syntax of the `for` loop. Here's how you can do this:
```java
long prod = 5;
boolean valid = true;
for(int x = 3; x <= 22 && valid; x += 5) {
prod = prod * prod;
}
```
- **Initialization:** `int x = 3` is placed in the initialization section of the `for` loop.
- **Condition:** `x <= 22 && valid` remains as the condition for the loop.
- **Increment:** `x = x + 5` is translated to `x += 5` and placed in the increment section of the `for` loop.
- **Loop Body:** The body of the loop remains unchanged.
By using a `for` loop, we can write more concise and potentially more readable code.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F0309cbb4-3056-403b-8eb0-8f64136b6051%2F5b255c14-8626-4899-8b9b-132397a8bb22%2Fa09ffk7_processed.png&w=3840&q=75)
