I'm trying to make the name array increment therefore it will advance to the next name. Here the program should make it more clear.

public class forloop 

{

    public static void main(String[] args)

    {

        String[] name;

            name = new String [3];

                 name[0] = "jannet";

                    name[1] = "Rose";

                         name[2] = "Pablyt";

                         

      int[] increment;

      increment = new int [3];

      

         while(increment[0]<=3)

         {          

            System.out.println(name[increment[0]]);

                increment[0]++;        

             }

                 }

                    }

I want to make the name index = the increment variable.

Why are you making an array of 'increment'?

String[] names = {"name1", "name2", "name3"};
        
for(int i = 0; i < names.length; i++){
    System.out.println(names[i]);
}

}

Well I was thinking that if the variable increment increased it should print the same array element with the same index.

By the way this line

String[] names = {"name1", "name2", "name3"};

Is the same as saying names = new int [3]?

It's short for

      String names = new String[3];
      names[0] = "name1";
      names[1] = "name2";      
      names[2] = "name3";

or this:

      String names = new String[]{"name1", "name2", "name3"};

You don't need another array to iterate over previous array, you just need a number, which represent the index accessed.

names[0] = "name1";

can be written

int i = 0;
names[i] = "name1";

by increasing the i, you are increasing the index of the name which is accessed.

Thanks now I will try to implement this into my JFrame which is giving me a headache but I believe I can do it
