Sep 25, 2015 · Idiomatic way of making an infinite loop in Java is while(true): System.out.print("Pick a number 1-10: "); int number = input.nextInt(); if (number == random) { System.out.println("Good!"); break; // This ends the loop. } else if (number > random) { System.out.println("Too Big"); } else if (number < random) { System.out.println("Too Small");

Jan 18, 2015 · else { System.out.println("Make sure your spelling is correct."); valid = false; } } while (!valid); The loop will repeat every time the final else is hit as it will set valid = false;. You could also encapsulate this in a function, which would be …

Aug 11, 2015 · You should look while or do-while in Java. You can get the idea from following example.. boolean status = true; String input = ""; while (status) { System.out.println("your input\n"); input = new Scanner(System.in).nextLine(); if (input.equals("valid")) { System.out.println("valid input"); status = false; } else { // not a valid input System ...

Apr 16, 2025 · The if-else statement in Java is a powerful decision-making tool used to control the program's flow based on conditions. It executes one block of code if a condition is true and another block if the condition is false. In this article, we will learn Java if-else statement with examples. Example: [GF

Java has the following conditional statements: Use if to specify a block of code to be executed, if a specified condition is true; Use else to specify a block of code to be executed, if the same condition is false; Use else if to specify a new condition to test, if the first condition is false

When you want to repeat an operation or a code sequence several times, you should use a loop. The loop is used to repeat a statement or block of statements as long as a particular condition is true. The term “control flow statement” is often used …

In Java, there are three main types of repetition loops: for, while and do-while. Let's explore each of them, understand how they work and learn how to apply them efficiently. The for loop is often used when the number of iterations is known. The syntax of the for loop is as follows: // Block of code to be repeated. Where:

This article will look at the while loop in Java which is a conditional loop that repeats a code sequence until a certain condition is met. We will start by looking at how the while loop works and then focus on solving some examples together.

Nov 27, 2023 · When working with if-else statements that have lots of conditions, it’s crucial to enhance the way we write the code so that it’s easy to read and maintain. In this article, we’ll explore several techniques to refine our syntax, accompanied by examples for a better understanding. 1. Importance of Clear and Efficient Code.

May 23, 2014 · This is an easier way to go, using a do-while loop and a switch. Also fixed choice Scanner keyboard = new Scanner(System.in); double weight; int choice; System.out.println("What is your weight in pounds?"); weight = keyboard.nextDouble(); do { System.out.println("Which planet would you like to see your weight on?\n 1.
