ipaddresses = IpAddresses.GenerateIps();
The array contain 56 items. I want item in index 2 to remove it to the end of the array. So the content in index 2 will be now in index 56. The array size will not change only the order of the items. Item 2 will be in place 56. So now i think index 3 will be index 2.
You can use System.arraycopy. This is similar to what happens when you remove an element from an ArrayList, only in your case you are moving the removed element to the end :
E element = elementData[index]; // get the element to be removed
int numMoved = elementData.length - index - 1;
// move all the elements that follow the moved element
if (numMoved > 0)
System.arraycopy(elementData, index+1, elementData, index, numMoved);
// put the moved element at the end
elementData[elementData.length - 1] = element;
Here elementData is the array and we move the element at the index position to the end.
Try this:
String text = "Cool";
text = text.replace(text.charAt(1), "") + text.charAt(1);
