### Concepts of Loops 1. **What is the difference between a "while" loop and a "do-while" loop?** 2. **Under what situation, the output of a "while" loop and a "do-while" loop will be different?** 3. **Write the CPU execution steps for the following program segment.** ```java for(int i=0; i<3; i++) { System.out.printf("Happy %d.\n", i+1); } ``` 4. **What is the advantage of declaring a counter before a "for" loop?** 5. **What is the difference between the following two program segments? What are output of each?** **Program Segment 1:** ```java for(int i=2; i>0; i--) { System.out.println(i); } System.out.println("Good Job!"); ``` **Program Segment 2:** ```java for(int i=2; i>0; i--) System.out.println(i); System.out.println("Good Job!"); ``` ### Diagram Description The image contains two program snippets in Java. Each snippet uses a `for` loop to iterate from 2 down to 1, printing the value of `i` each time. The first snippet includes braces `{}` around the loop's content, while the second does not, affecting which statements are considered as part of the loop. The "Good Job!" message is printed outside of the loop in both cases, so it will execute once after the loop ends.

Can you help me with these Java questions
### Concepts of Loops

1. **What is the difference between a "while" loop and a "do-while" loop?**

2. **Under what situation, the output of a "while" loop and a "do-while" loop will be different?**

3. **Write the CPU execution steps for the following program segment.**

   ```java
   for(int i=0; i<3; i++)
   {
       System.out.printf("Happy %d.\n", i+1);
   }
   ```

4. **What is the advantage of declaring a counter before a "for" loop?**

5. **What is the difference between the following two program segments? What are output of each?**

   **Program Segment 1:**
   ```java
   for(int i=2; i>0; i--)
   {
       System.out.println(i);
   }
   System.out.println("Good Job!");
   ```

   **Program Segment 2:**
   ```java
   for(int i=2; i>0; i--)
       System.out.println(i);
   System.out.println("Good Job!");
   ```
