I have a for loop

for (Object obj : getNeighbors(1, true, Minnow.class)) 
        {
            getWorld().remove((Minnow)obj);
        }

and I was wondering how to test it. My understanding of loops is kind of fuzzy, so I don't know how to set up a test and any help would be greatly appreciated.

What exactly would you be testing it for? what information should the test provide ?

Ok so I literally don't understand loops at all but for method with if statements or while statements we have to make sure we set up the situation to test both options. Ex if this is the method

public void go()
{
    if (sky = blue)
    {
        move();
    }
}

Then I'll have to test methods

public void testGo1()
{
    sky = blue;
    move();
}

public void testGo2()
{
    sky = yellow; 
    move();
}

So this is what my beginner brain understands. An explanation of what the for loop means would probably help.

If you have done while statements, then you can do a for statement. The following two codes are equivalent:

int i;
for (i = 0; i<10; i++)
{
    // whatever
}

// and
int i=0;
while (i < 10)
{
    // whatever
    i = i + 1;
}
