📚 Topic Summary
The 'for' loop in Java is a control flow statement that allows you to repeatedly execute a block of code. It's particularly useful when you know how many times you want to iterate. The initialization part of the 'for' loop is executed only once at the beginning of the loop. It typically involves declaring and initializing a loop counter variable. However, improper initialization can lead to infinite loops or incorrect results. Understanding best practices and potential pitfalls ensures efficient and bug-free code.
A common mistake is initializing the loop counter with an incorrect starting value or updating it improperly in the loop's update statement. This can cause the loop to execute more or fewer times than intended, leading to logic errors in your program. Careful attention to detail in the initialization, condition, and update statements is crucial for writing effective 'for' loops.
🧮 Part A: Vocabulary
Match each term with its correct definition:
| Term |

A. A statement that is executed after each iteration of the loop. |
| 2. Condition |
B. The part of the 'for' loop that is executed only once at the beginning. |
| 3. Update |
C. A loop that never terminates. |
| 4. Iteration |
D. A boolean expression that determines whether the loop continues. |
| 5. Infinite Loop |
E. A single execution of the loop body. |
✍️ Part B: Fill in the Blanks
Complete the following paragraph using the words provided: initialization, condition, update, body, counter.
The 'for' loop consists of three main parts: the __________, the __________, and the __________. The __________ part is executed once at the beginning. The __________ is evaluated before each iteration to determine if the loop should continue. The loop __________ contains the code that is executed repeatedly.
🤔 Part C: Critical Thinking
Describe a scenario where using an incorrect initialization value in a 'for' loop could lead to a significant error in a program. How would you debug this issue?
