How to split a string array into small chunk arrays in java?

You can use Arrays.copyOfRange(int[] original, int from, int to)
The code could be something like this:

int chunk = 2; // chunk size to divide
for(int i=0;i<original.length;i+=chunk){
    System.out.println(Arrays.toString(Arrays.copyOfRange(original, i, Math.min(original.length,i+chunk))));
}
