Repeating Tasks in

Java

Introduction

● (^) Java provides control flow statements to execute code repeatedly ● (^) Looping statements allow repeating tasks: ● (^) while loop ● (^) do-while loop ● (^) for loop

Examples:

while (i < 10) { System.out.println(i); i++; }

do-while Loop

● (^) Similar to while loop, but condition checked after first iteration ● (^) Code block executes at least once ● (^) Syntax: ● (^) do { // code to execute ● (^) } ● (^) while (condition);

Examples

● (^) for (int i=0; i<10; i++) { System.out.println(i); ● (^) }

Conclusion

● (^) Loops allow repeating execution of code blocks ● (^) while, do-while, for, enhanced for provide repeating control flow
