Printing all the numbers less than Equal to 10 without using the Increment operator i in this case starts with 0 as the index in any looping statement has to start with the index of 0. Iterating an Array by making use of do-while loop in Java Printing all the Numbers less than equal to 10 This is more often used when the iterations and their count are fixed in number, whereas in the case of the do-while loop, the number of iterations is not known before-hand but can change dynamically.īelow are the examples of all the numbers till 10: Example #1 The basic difference between a do-while and a very well-known loop is that the number of iterations is needed to be known in the loop and the initial value and the value which is being incremented.The basic difference between the while and the do-while loop is that while the former one looks for the pre-conditions, the latter one targets the postconditions. If the condition is met, then the loop is reiterated otherwise, the loop is exited from the block. The compiler executor then enters the function execution block executes whatever is there within the block of statements, and then comes out to check the expression part where the condition is compared. For a do-while loop to work, the condition is not necessary to be met as this loop also works well for the first time even when the condition is not met.How does a do-while loop work in Java?įollowing are the explanation for how does do-while loop work in Java: The while statement, in the end, is used to evaluate the expression and then apply a postcondition to check whether the intended case is meeting the requirements and should be further looped. The block of statements is the set of statements that are executed inside the do-while looping construct.
#JAVA WHAT DOES FOR DO CODE#
The do command in this syntax ensures that the code is executed at least once, even when the expression is not executed, or the condition is not checked. If either of the values could not be found, then the compiler throws a compile-time error.
The expression which is mentioned right after the while block is used to return a Boolean value, i.e.
