" for  "  loop in Java / Selenium

              for (int i = 0; i <= 5; i++) {

                     System.out.println("The value of i is : " + i);

              }

Answer :

The value of i is : 0

The value of i is : 1

The value of i is : 2

The value of i is : 3

The value of i is : 4

The value of i is : 5

              for (int i = 0; i <= 5; i = i + 2) {

                     System.out.println("The value of i is : " + i);

              }

Answer :

The value of i is : 0

The value of i is : 2

The value of i is : 4

              for (int i = 5; i > 0; i--) {

                     System.out.println("The value of i is : " + i);

              }

Answer :

The value of i is : 5

The value of i is : 4

The value of i is : 3

The value of i is : 2

The value of i is : 1

              for (int i = 5; i > 0; i = i - 2) {

                     System.out.println("The value of i is : " + i);

              }

Answer :

The value of i is : 5

The value of i is : 3

The value of i is : 1

" break  " in the for  loop 

If you want to break/stop the for loop in certain condition then you can use "break":

               for (int i = 0; i <= 5; i++) {

                   System.out.println("The value of i is : " + i);

                  

                   if(i==3){

                        break;

                   }       

            }

Answer :

The value of i is : 0

The value of i is : 1

The value of i is : 2

The value of i is : 3


" continue  " in the for  loop 

If you want to continue the for loop in certain condition then you can use "continue":

               for (int i = 0; i <= 5; i++) {

                   System.out.println("The value of i is : " + i);

                  

                   if(i==3){

                        continue;

                   }       

            }

Answer :

The value of i is : 0
The value of i is : 1
The value of i is : 2
The value of i is : 3
The value of i is : 4
The value of i is : 5

 

 

Another way of writing for loop:

 

             //Array

             String[] str = {"TX", "NY", "CA"};

             System.out.println("-------Array using For Loop--------");

             for (int i = 0; i < alist.size(); i++) {

                    System.out.println(str[i]);

             }

 

             // for loop another way

             System.out.println("-------Array using For Loop with semicolon--------");

             for (String x : str) {

                    System.out.println(x);

             }

            

             //Arraylist

             List<Integer> arlist = Arrays.asList(5,6,7);// ArrayList

             // 1. for loop

             System.out.println("-------ArrayList using For Loop--------");

             for (int i = 0; i < alist.size(); i++) {

                    System.out.println(arlist.get(i));

             }

 

             // for loop another way

             System.out.println("-------ArrayList using For Loop with semicolon--------");

             for (Integer x : arlist) {

                    System.out.println(x);

             }

 

Output:

-------Array using For Loop--------

TX

NY

CA

-------Array using For Loop with semicolon--------

TX

NY

CA

-------ArrayList using For Loop--------
