Practice 1: Counting Loop
- Trace the provide code segment and predict the output.
- Verify your prediction is correct by running the code in the Java Playground.
- If the code results in an infinite loop, explain why. How would you modify the code so that it is no longer an infinite loop? Make this change.
- If the code causes the loop to not execute at all, explain why. How would you modify the code so that the loop iterates at least 1 time?
Practice 2: Print number
- Trace the provide code segment and predict the output.
- Verify your prediction is correct by running the code in the Java Playground.
- If the code results in an infinite loop, explain why. How would you modify the code so that it is no longer an infinite loop? Make this change.
- If the code causes the loop to not execute at all, explain why. How would you modify the code so that the loop iterates at least 1 time?
Practice 3: Print i
- Trace the provide code segment and predict the output.
