♾️ Infinite Loops in Java

? Quick Overview

An infinite loop in Java is a loop that never stops executing because its termination condition is always true or never reached. These loops are common in servers, games, and background processes.

? Key Concepts

Loop condition never becomes false
Used intentionally in real-time programs
Requires a break or external stop to exit
Can occur accidentally due to logic errors

? Syntax & Theory

Java supports infinite loops using while, for, and do-while constructs. The most common form uses while(true).

? Code Example(s)

? View Code Example

// Infinite loop using while(true)
while(true){
System.out.println("Running forever...");
}

? View Code Example

// Infinite loop using for statement
for(;;){
System.out.println("This loop has no end condition");
}

? Live Output / Explanation

? What Happens?

The program continuously prints messages to the console. It will only stop if the program is manually terminated or a break statement is introduced.

✅ Tips & Best Practices

Always verify loop conditions carefully
Use infinite loops only when truly required
Provide safe exit logic using break
Avoid infinite loops in UI or main threads

? Try It Yourself

Create an infinite loop that stops after 5 iterations using break
Modify a for loop to intentionally make it infinite
Observe CPU usage when an infinite loop runs
