Loop "FOR"

for(initialization; condition ; increment/decrement)

   statement(s);

//////////  Standart use of "for"
 for(int a=29; a>=1; a--){
              System.out.println("The value of a is: "+a);
     
////////// Infinite "for" loop

////////// For loop example to iterate an array:
class ex{
    public static void main(String args[]){
         int arr[]={3,15,85,2};
         //i starts with 0 as array index starts with 0 too

////////// Enhanced For loop

////////// for-each loop
     class ex {
   public static void main(String[] args) {
