Question

private JEditorPane textArea[]= new JEditorPane[maxTabs];

I’ve got this table,I want to delete some elements and move the others, for example if I delete the second element, the third will be instead of the second and so on.

Answer 1

Depending on scenario you are interested (we remove for example element at position 1)

1) If elements should be shifted to left and last element should be set to 0 or null depending on type of array like

before [0,1,2,3,4]
after [0,2,3,4,0]

you can use

System.arraycopy(textArea, index+1, textArea, index, textArea.length-index-1);
array[array.length-1]=null;

2) when you want to replace old array with new one that wont contain selected element like

before [0,1,2,3,4]
after [0,2,3,4] //we removed element at position 1 (new array is smaller)

you can try something like this

List<JEditorPane> listCopy = new ArrayList<JEditorPane>(
        Arrays.asList(textArea));
listCopy.remove(index);
textArea = listCopy.toArray(new JEditorPane[listCopy.size()]);
