Hi,

I am trying to acces to the specified index of the array of the ArrayList and then I would like to assign it tot the specific
variable, course name. This is what I am doing:

String courseName;
for(int i = 0; i< dlayer.getStudentList().getContainer().size(); i++)
{
	courseName = dlayer.getStudentList().getContainer().get(i)[2]; 
        //error: The type of the expression must be an array type but it resolved to Object



//then I am planning to do other things in the loop with that courseName but first 
//I need to find the way how to assign some data to it
}

Thank you for help

So to get a value from an index of an array list, you can:

get

public E get(int index)
Returns the element at the specified position in this list.

I dont know why you doing

 courseName = dlayer.getStudentList().getContainer().get(i)[2];

arraylist dont use [index] to go arround. get(index) will give you the value of the specific index.

[pbl]

for that stemen to be valid

courseName = dlayer.getStudentList().getContainer().get(i)[2];

dlayer.getStudentList().getContainer().get(i) has to return an array of String
so getContainer() has to be a ArrayList<String[]>

You are right that to get a value from an index of an array list, you can:

get

public E get(int index)
Returns the element at the specified position in this list.

but the thing is you get all the data which is on the specific index of the ArrayList.
I was doing as you described but I was getting all the data from the specific index line.
The thing is that I wanted to get the specific value from the specific index of the array which is in the ArrayList.
It is the reason I used

 courseName = dlayer.getStudentList().getContainer().get(i)[2]; 

Also, the reason why I used the code above because I found similar idea in other forum.

thank you for trying to help.!!!!!

Thank you. it worked in my code.
