I want to make a Snake game, but I don't know how to make the tail move together with the head. I want to use an array but I don't know how to program it to move together with the head.

Add to the body class, the following field:
Add the field to the class of the head as well, if a different class.
Then add the following method to the body class:
With this the head can control both movement and adding length using:
No other movement codes is required except for that which determines the new location coordinates of the head.
The codes given were not tested, but I do not foresee any issues with them.
private Actor behind;
public void move(Actor ahead, boolean addBehind)
{
if (behind != null) behind.move(this, addBehind);
else if (addBehind) getWorld().addObject(behind = new Body(), getX(), getY());
setLocation(ahead.getX(), ahead.getY());
}behind.move(this, false); // moves body without adding length (false), in this case setLocation(<<newX>>, <<newY>>); // moving the head to its next location
