Feb 24, 2014 · Use a while or for loop with the entire code which you would like to loop. For example: For example: while( IsConditionTrue() ){ System.out.println ("Enter Gender (m/f): "); char gender = body.nextLine().charAt(0); // more code // code to update the variable using which the condition is checked }

Oct 15, 2014 · I am writing a simple guessing game program where the user will input a number to try and guess a randomly generated number. If they get the number right I want to give them the option to play again. Here is my code:

When you know exactly how many times you want to loop through a block of code, use the for loop instead of a while loop: Statement 1 is executed (one time) before the execution of the code block. Statement 2 defines the condition for executing the code block. Statement 3 is executed (every time) after the code block has been executed.

Java for loop is used to run a block of code for a certain number of times. The syntax of for loop is: for (initialExpression; testExpression; updateExpression) { // body of the loop }

Apr 7, 2025 · Java while loop is a control flow statement used to execute the block of statements repeatedly until the given condition evaluates to false. Once the condition becomes false, the line immediately after the loop in the program is executed. Let's go through a simple example of a Java while loop: [GFGT

Finally, for Java 11 and above, there is a new repeat (int count) method specifically for this purpose "abc".repeat(12); Alternatively, if your project uses java libraries there are more options. For Apache Commons: StringUtils.repeat("abc", 12); For Google Guava: Strings.repeat("abc", 12);

How while loop in Java works? The while loop is used to iterate a sequence of operations several times. In other words, you repeat parts of your program several times, thus enabling general and dynamic applications because code is reused any number of times.

In Java, you use the for loop when you want to repeat an operation a specific number of times. A for loop is described as a counting loop; in other words, the loop repeats a code sequence a predetermined number of times.

Apr 17, 2025 · Java for loop is a control flow statement that allows code to be executed repeatedly based on a given condition. The for loop in Java provides an efficient way to iterate over a range of values, execute code multiple times, or traverse arrays and collections. Now let’s go through a simple Java for loop example to get the clarity first. Example:

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 …
