### Transcription of Java Code Example

**Purpose**: Explanation of the number of operations executed in a Java program.

**Java Code Example**:

```java
public class AddThree
{
public static void main(String[] args)
{
StdOut.print("Type the first integer: ");
int x = StdIn.readInt();
StdOut.print("Type the second integer: ");
int y = StdIn.readInt();
StdOut.print("Type the third integer: ");
int z = StdIn.readInt();
int sum = x + y + z;
StdOut.print("Their sum is " + sum);
}
}
```

**Explanation**:

This Java program is designed to read three integers from the standard input and display their sum. Each `StdOut.print` represents a DISPLAY operation, and each `StdIn.readInt()` represents a READ operation, as per the rules for counting operations in pseudocode.

- **Operation Details**:
- The program contains a total of 7 operations:
- 3 DISPLAY operations for prompting user input.
- 3 READ operations to capture the integers.
- 1 arithmetic operation to compute the sum of the integers.

This example can be used to illustrate basic input/output functionality and counting operations in a Java program.

Understanding ifStatements Summary In this lab, you complete a prewritten Java program for a carpenter who creates personalized house signs. The program is supposed to compute the price of any sign a customer orders, based on the following facts: The charge for all signs is a minimum of $35.00. The first five letters or numbers are included in the minimum charge; there is a $4 charge for each additional character. If the sign is made of oak, add $20.00. No charge is added for pine. Black or white characters are included in the minimum charge; there is an additional $15 charge for gold-leaf lettering. Instructions 1. Ensure the file named HouseSign.java is open. 2. You need to declare variables for the following, and initialize them where specified: A variable for the cost of the sign initialized to 0.00 (charge). A variable for the number of characters initialized to 8 (numChars). A variable for the color of the characters initialized to "gold" (color). A variable for the…
