Why is iteration important?
It allows us to execute code repeatedly, forming the backbone of complex algorithms.
What is the key to avoiding infinite loops?
Ensuring the loop condition eventually becomes false.
When is a for loop preferred?
When you know the number of iterations in advance.
How can loops be used to manipulate strings?
Using string methods like .length() and .substring() within loops to process strings character by character.
What is the purpose of nested iterations?
To repeat a set of actions for each element in a collection of elements, often used with 2D arrays.
Why is tracing loops important?
It helps in debugging and understanding complex loop behavior.
What happens if a while loop's condition is initially false?
The loop body will never execute.
What is the role of initialization in a for loop?
It's executed once at the start of the loop to set up the loop variable.
What is the role of the condition in a for loop?
It's checked before each iteration to determine if the loop should continue.
What is the role of the iteration statement in a for loop?
It's executed after each iteration to modify the loop variable.
What is iteration?
Repeating a block of code.
What is a while loop?
A loop that executes while a condition is true.
What is a for loop?
A loop with initialization, condition, and iteration in one line.
What is a nested loop?
A loop inside another loop.
What is string traversal?
Processing a string character by character.
What is tracing?
Manually executing code step-by-step.
What is an infinite loop?
A loop that never terminates.
What is the body of a loop?
The code that is executed repeatedly.
What is a loop condition?
The boolean expression that determines if a loop continues.
What is the modifier in a loop?
The statement that changes the loop variable.
What are the differences between a while loop and a for loop?
While Loop: Condition checked before each iteration, more flexible. | For Loop: Initialization, condition, and increment in one line, preferred when iterations are known.
What are the differences between charAt() and substring()?
charAt(): Returns a single character at a specified index. | substring(): Returns a new string that is a substring of this string.
