![]() ![]() The do-while loop : This executes a statement at least for one timeĮnhanced for loop : This for loop also works with an array of any typesĪ for loop is a repetition control structure that allows you to efficiently write a loop that needs to execute a specific number of times. The statement may be a single statement or a block of statements, and the condition. The while loop : This executes a statement for an unknown number of times With the help of a while loop in Java, we can continuously execute a block of codes again and again until a particular condition is true. The Java while loop has two components, a condition and a statements. The for loop : This executes a statement for a particular number of times What are the various types of Loops in Java? In Java we have three types of basic loops: for, while, and do-while. Loops in Java:Īs explained above - Loops are used to execute a set of statements repeatedly until a particular condition is satisfied. In Java, while loops are a great way to generate a series of numbers, say from 1 to 10, which is exactly what the class in our while loop example code below does: import java.io. Loops are specifically designed to perform repetitive tasks with one set of code. Java supports loops, which are used to repeatedly run a block of code until a specific condition is met. The while loop is considered as a repeating if statement. While loop in Java comes into use when we need to repeatedly execute a block of statements. The while loop can be thought of as a repeating if statement. This is where loops come into the picture. Java while loop is a control flow statement that allows code to be executed repeatedly based on a given Boolean condition. while loop in Java is a control flow statement that allows code to be executed repeatedly based on a given Boolean condition. Computers are now very smart and meant to reduce the task, although the computer would not mind executing your 1000 lines but still it wants you to play smart on that. The loop consists of the keyword while followed by an expression and curly braces. ![]() Coding 1000 lines to do this would be mundane and stupidity. ![]() Rectangle box1 new Rectangle (5, 10, 20, 30) Rectangle box2 box1 Rectangle. However, when you compare two object reference variables with the '' operator, you are actually testing whether the two references point to the same object. For example, imagine you have to write a program that performs a repetitive task such as printing 1 to 1000. The operator can be used to test primitive values for equality (i.e. ![]() If a correct answer is received, the loop terminates and we congratulate the player.There can be a situation where you need to execute a block of code again and again for a specific number of times. do-while loop is similar to while loop statement but do-while loop executes all the statements in the block, at least once and then checks the condition at the. The loop must run as long as the guess does not equal Daffy Duck. the for loop, the while loop, and the do-while loop. In the loop body we receive input from the player and then the loop condition checks whether it is the correct answer or not. The do while loop is very similar to the while loop with one distinct difference. In a guessing game we would like to prompt the player for an answer at least once and do it until the player guesses the correct answer. To put it simply, we’re going to read text typed by the player. This is the standard input stream which in most cases corresponds to keyboard input. The example uses a Scanner to parse input from System.in. println ( "Congratulations, you guessed my name correctly!" ) while (condition ) while ( ! "Daffy Duck". It consists of the while keyword, the loop condition, and the loop body. The while loop is the most basic loop construct in Java. ![]()
