Java – rotate array

Therefore, the goal is to rotate the elements in the array once

This is what I have:

for (int x = 0; x <= array.length-1; x++){
    array[x+a] = array[x];
}

However, this does not explain when [x a] is greater than the length of the array I read that I should store larger data in different arrays, but as variables, I'm not sure this is the best solution Thank you in advance

Solution

Add modulus group length to code:

// create a newArray before of the same size as array

// copy
for(int x = 0; x <= array.length-1; x++){
  newArray[(x+a) % array.length ] = array[x];
}

You should also create a new array to copy to so that you do not overwrite the values you need later
