Determine which level of the text that it is currently parsing

So I have this code in my program, and there are multiple variations of it. Just looking at it, I feel like there must be a way to make it more efficient, but I can't think of anything. Just looking at it, does anyone have any ideas?

Essentially, what the code does is it determines which level of the text that it is currently parsing. If it it is in level 0, it adds that body of text to the aMainSection ArrayList.

If it it in level 1, it adds that body of text to aChildSection of aMainSection (An ArrayList within the aMainSection ArrayList). Then it sets the aMainSection text to 'parent text' within a new ArrayList.

etc.

Notes:

• aMainSection & aChildSection are arrayLists of type Section (A custom class)

• levelCount is just an array of type int, size 10 (abstract number)

Code

```
// Adds the passed in heading text to the appropriate section
public static void addSectionText(String text)
{
if (currentLevel == 0)
{
aMainSection.get(levelCount[0] - 1)
.addSection(text);
}
else if (currentLevel == 1)
{
aMainSection.get(levelCount[0] - 1)
.aChildSection.get(levelCount[1] - 1)
.addSection(text);

aMainSection.get(levelCount[0] - 1)
.aChildSection.get(levelCount[1] - 1)
.addParentSection(
aMainSection.get(levelCount[0] - 1)
.getSection());
}
else if (currentLevel == 2)
{
aMainSection.get(levelCount[0] - 1)

.aChildSection.get(levelCount[1] - 1)
.aChildSection.get(levelCount[2] - 1)
.addSection(text);

aMainSection.get(levelCount[0] - 1)
.aChildSection.get(levelCount[1] - 1)
.aChildSection.get(levelCount[2] - 1)
.addParentSection(
aMainSection.get(levelCount[0] - 1)
.getSection());

That much repetition does have a smell to it. Can you simplify it by saving and reusing intermediate values similar to what I've shown below?

else if (currentLevel == 3)
    {
        Section level0Section = aMainSection.get(levelCount[0] - 1);
        Section level1Section = level0Section.aChildSection.get(levelCount[1] - 1);
        Section level2Section = level1Section.aChildSection.get(levelCount[2] - 1);
        Section level3Section = level2Section.aChildSection.get(levelCount[3] - 1);
        level3Section.addSection(text);

        level3Section.addParentSection(level0Section.getSection());

        level3Section.addParentSection(level1Section.getSection());

        level3Section.addParentSection(level2Section.getSection());
   }
