Infinite Loop
What is an infinite loop?
An infinite loop is a loop that continues executing indefinitely without a condition that would cause it to terminate. This can result in your program becoming unresponsive or consuming excessive system resources.
Here's an example of an infinite loop in Java:
Main
9
1
2
3
while (true) {
// Code to be executed indefinitely
}
123while (true) { // Code to be executed indefinitely }
To avoid infinite loops:
Ensure a proper termination condition: Double-check that your loop has a well-defined termination condition. The condition should eventually evaluate as false, allowing the loop to exit.
Main
9
1
2
3
4
5
int count = 0;
while (count < 10) {
// Code to be executed
count++;
}
12345int count = 0; while (count < 10) { // Code to be executed count++; }
Utilize loop control statements such as break or return to explicitly exit the loop when a specific condition is met.
Main
9
1
2
3
4
5
6
while (true) {
// Code to be executed
if (condition) {
break; // Exit the loop
}
}
123456while (true) { // Code to be executed if (condition) { break; // Exit the loop } }
1. Which loop construct in Java is best suited when the number of iterations is known?
2. Which keyword is used to exit a loop prematurely?
Everything was clear?
