While Loop in Java - Quipoin

1. While Loop while loop in Java

2. Overview • While loop is a pre-test loop which means the condition will be first checked then the statement will execute.  • The while loop repeats the statement till the condition is true. •  When the condition is false then execution comes out from the loop. •  In the while loop,  based on the condition block statement is executed.  •  it is also known as an entry control loop.

3. class WhileLoop { public static void main(String args[]) { // initialization expression int i = 1; // test expression while (i < 4) { System.out.println("Quipo House"); i++; // update expression } } } Program • class WhileLoop { • public static void main(String args[]) { • // initialization expression int i = 1; • // test expression • while (i < 4) { • System.out.println("Quipo House"); • i++; // update expression • } • } • }

4. Features: • Condition-based Execution: • The while loop repeatedly executes a block of code as long as a specified condition is true. The condition is evaluated before each iteration, and if it becomes false, the loop terminates, and the program continues with the next statement after the loop. • Initialization and Increment/Decrement: • Typically, a while loop includes initialization of loop control variables before the loop starts and an increment or decrement operation within the loop body. These operations ensure that the loop eventually reaches a state where the condition becomes false, leading to termination. • Flexible Loop Structure: • The while loop is a versatile construct that allows for flexible loop structures. It is suitable for scenarios where the number of iterations is not known beforehand, and the loop continues until a specific condition is met. It provides control over the loop's execution based on the dynamic evaluation of the condition.
