### Introduction to Java Programming - Unit 1 Milestone 1

#### Question:
Which of these programs would produce the output `goodwordgood`?

##### Option A:
```java
String word = "good";
System.out.println(word + "word" + word);
```

##### Option B:
```java
String word = "good";
System.out.println(word + word + word);
```

##### Option C:
```java
String word = "good";
System.out.println("word" + "word" + "word");
```

##### Option D:
```java
String word = "good";
System.out.println("word" + word + "word");
```

---

#### Analysis:

1. **Option A**:
   - Code Explanation:
     ```java
     String word = "good";
     System.out.println(word + "word" + word);
     ```
     - This option assigns the string `"good"` to the variable `word`.
     - The `System.out.println()` statement concatenates the value of `word`, the string `"word"`, and again the value of `word` and outputs it to the console.
     - Output: `goodwordgood`

2. **Option B**:
   - Code Explanation:
     ```java
     String word = "good";
     System.out.println(word + word + word);
     ```
     - This option assigns the string `"good"` to the variable `word`.
     - The `System.out.println()` statement concatenates the value of `word` three times and outputs it to the console.
     - Output: `goodgoodgood`

3. **Option C**:
   - Code Explanation:
     ```java
     String word = "good";
     System.out.println("word" + "word" + "word");
     ```
     - This option assigns the string `"good"` to the variable `word`.
     - The `System.out.println()` statement concatenates the string `"word"` three times and outputs it to the console.
     - Output: `wordwordword`

4. **Option D**:
   - Code Explanation:
     ```java
     String word = "good";
     System.out.println("word" + word + "word");
     ```
     - This option assigns the string `"good"` to the variable `word`.
     - The `System.out.println()` statement concatenates the string `"word"`, the value of `word`, and the string `"word"`
