Show your work.```javaint y = 0, i = 0;while (i < 10) { i = i + 1; y = i; System.out.println(y);}```**Explanation:**- This code initializes two integer variables, `y` and `i`, to 0.- It enters a `while` loop that runs as long as `i` is less than 10.- Inside the loop, `i` is incremented by 1, then `y` is set to the value of `i`.- The value of `y` is printed to the console each time through the loop.- Thus, the output will be numbers 1 to 10 each printed on a new line.#### 6.

Array

The simplest way to start thinking about an array is as a collection, or a set of elements. In programming, these elements may be constants, variables, functions and pointers.

Question

### Transcription and Explanation

#### 5. What is the output for y? Show your work.

```java
int y = 0, i = 0;
while (i < 10) {
i = i + 1;
y = i;
System.out.println(y);
}
```

**Explanation:**
- This code initializes two integer variables, `y` and `i`, to 0.
- It enters a `while` loop that runs as long as `i` is less than 10.
- Inside the loop, `i` is incremented by 1, then `y` is set to the value of `i`.
- The value of `y` is printed to the console each time through the loop.
- Thus, the output will be numbers 1 to 10 each printed on a new line.

#### 6. How many times "Halloween is here" will be printed?

```java
for(i = 1; i <= 19; i++)
for(k = 1; k <= 3; k++)
System.out.println("Halloween is here");
```

**Explanation:**
- This code includes a nested loop structure.
- The outer loop with variable `i` runs from 1 to 19, inclusive, meaning it executes 19 times.
- The inner loop with variable `k` runs from 1 to 3 for each iteration of the outer loop, meaning it executes 3 times per iteration of the outer loop.
- Therefore, the statement `"Halloween is here"` is printed \(19 \times 3 = 57\) times.

#### Java Statement to Compute Square Root

**Write a Java Statement to compute square root of 36:**

```java
System.out.println(Math.sqrt(36));
```

**Explanation:**
- This Java statement uses the `Math.sqrt()` method to calculate the square root of 36.
- The result, which is 6, is printed to the console.
