The syntax of the while loop is: while (testExpression) { // body of loop } Here, A while loop evaluates the textExpression inside the parenthesis (). eval(ez_write_tag([[336,280],'tutorialcup_com-box-4','ezslot_8',622,'0','0']));Hence in the 1st iteration, when i=1, the condition is true and prints the statement inside java while loop. In your while loop, you specify the input.length() > 1 condition. Well when you input a single character your code SHOULD "surpass" meaning skip over the loop, because a single character does not have length greater than 1. In the while condition, we have the expression as i<=5, which means until i value is less than or equal to 5, it executes the loop. It then again checks if i<=5. So essentially, my while loop will evaluate the first two conditions when the length condition is not present; however when I had the length condition, the loop only evaluates that condition. rev 2021.1.8.38287, Sorry, we no longer support Internet Explorer, Stack Overflow works best with JavaScript enabled, Where developers & technologists share private knowledge with coworkers, Programming & related technical career opportunities, Recruit tech talent & build your employer brand, Reach developers & technologists worldwide.
