Question

When I have a for loop, I use the i to refer to the elements of my array, objects, etc.

Like:
Current item: myArray[i]
Next item: myArray[i+1]
Previous item: myArray[i-1]

But at the moment, I’m using a foreach loop ( for (Object elem : col) { ).
How do I refer to the previous item?
(I need to do a search an ‘array’, which I’m doing with for (Object object : getComponents()).

But when it returns true (so it finds what I look for), it should perform the code on the previous and the next item.

Clarification: I have java.awt.Component elements!

Answer 1

JButton prev, next, curr;
Component[] arr = getComponents();

for(int i=1;i<arr.length-1;i++) {
    if (yourcondition == true) {
        curr = (JButton) arr[i];
        prev = (JButton) arr[i-1];
        next = (JButton) arr[i+1];
    }
}
