### Java Conditional Statements Example

This example demonstrates the use of conditional statements in Java to produce various outputs based on the value of the integer variable `y`.

#### Code Explanation

```java
int y = 40;
if (y > 10)
    System.out.println("Apple");
else if (y > 20)
    System.out.println("Pear");
else if (y > 30)
    System.out.println("Strawberry");
else
    System.out.println("Blueberry");
```

#### Analysis

1. **Variable Initialization:**
   - The variable `y` is initialized with the value `40`.

2. **Conditional Statements:**
   - The first condition checks if `y` is greater than `10`.
   - If true, the output will be `"Apple"`.
   - Subsequent `else if` conditions are present, but since the first condition holds true (as `40 > 10`), none of the other conditions are evaluated, and `"Apple"` is printed immediately.

3. **Output:**
   - The only output in this scenario is `"Apple"` due to the conditions set by the if-else structure.

#### Task 28

**Instructions:**
List all the possible outputs for the following expression:
```java
f = 1 + (int)(Math.random() * 3)
```

**Explanation:**
- The expression uses `Math.random()`, which generates a random double between `0.0` (inclusive) and `1.0` (exclusive).
- Multiplying by `3` scales the range to `0.0` to `3.0`.
- Casting the result to an integer `(int)` gives possible values `0`, `1`, or `2`.
- Adding `1` shifts the possible values to `1`, `2`, or `3`.

**Possible Outputs:**
- `1`
- `2`
- `3` 

This randomness introduces variability in output during different executions.

Expert Solution
Explanation

NOTE - As per our guideline we can answer only one question, please repost the other parts as a separate question.

Here in the code, we have variable y with the value as 40.

Next, we have nested the if-else statement to check the range of y and print the message to the console.

In the nested if-else statements as soon as any condition is satisfied then other parts are not checked.
