Iterate through string array in Java

Question

I have String array with some components, this array has 5 components and it vary some times. What I would like to do is to iterate through that array and get the first comp

Answer 1

String[] elements = { "a", "a", "a", "a" };

for( int i = 0; i < elements.length - 1; i++)
{
    String element = elements[i];
    String nextElement = elements[i+1];
}

Note that in this case, elements.length is 4, so you want to iterate from [0,2] to get elements 0,1, 1,2 and 2,3.
