Question

So for my current program, I am currently doing this:

Java Code

        ArrayList<Section> aMainSection = new ArrayList<Section>();
        Section aSection = new Section();
        aSection.setName("Document 1");
        aSection.setSection("Section 1");
        aSection.setText("Text 1");
        Section aSection2 = new Section();
        aSection2.setName("Document 2");
        aSection2.setSection("Section 2");
        aSection2.setText("Text 2");
        Section aSection3 = new Section();
        aSection3.setName("Document 3");
        aSection3.setSection("Section 3");
        aSection3.setText("Text 3");

But what I want to be able to do is create a for loop in which when the condition is met, I can just create a new Section. However, I do not know how to increment variables in Java. I would assume it should be possible, somehow, but I know it’s not as simple as concatenating an integer value to the end of the variable name. Any help would be appreciated, thank you.

Sounds like you want to do this:

ArrayList<Section> aMainSection = new ArrayList<Section>();
for(int i = 0; i < 3; i++)
{
    Section aSection = new Section();
    aSection.setName("Document "+(i+1));
    aSection.setSection("Section "+(i+1));
    aSection.setText("Text "+(i+1));
    aMainSection.Add(aSection);
}

If you don’t know how many times you want to do it before hand try this:

ArrayList<Section> aMainSection = new ArrayList<Section>();
int sectionNumber = 1;
boolean done = false;
while(!done)
{
    Section aSection = new Section();
    aSection.setName("Document "+ sectionNumber);
    aSection.setSection("Section "+ sectionNumber);
    aSection.setText("Text "+ sectionNumber);
    aMainSection.Add(aSection);

    sectionNumber++;
    done = <put something interesting here>
}
