Looping Statement

  • While loop:
    A while loop checks the condition before executing the loop body.
    When to use while loop:
    When you don’t know in advance how many times the loop will run
    When the condition depends on user input or runtime values

  • For loop
    A for loop is used when you know how many times the loop should run.
    When to use for loop:
    When the number of iterations is fixed or known

  • do-while loop
    A do-while loop in Java is a loop that executes the code at least once, even if the condition is false.
    the condition is checked after the loop body runs.
    Example-while loop:
    public class LoopingStatement {

    public static void main(String[] args) {
    int i=1;
    while(i<=5)
    {
    System.out.println(i);
    i++;
    }

    }
    }
    Example-for loop:
    public class LoopingStatement {

    public static void main(String[] args) {

    for(int i=1; i<=10; i++) 
    {
        if(i%2 == 0)
        {
            System.out.println("even numbers :"+ i);
        }
        else
        {
            System.out.println("odd numbers :"+ i); 
        }
    }
    

    }
    }
    Example-do-while:
