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.java


              123
            
while (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.java


              12345
            
int 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.java


              123456
            
while (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?

Tutto è chiaro?
