Wall
temporarily save current location
move
if touching a wall, move back to saved location
int x=getX(), y=getY(); //-- insert moving code here if (isTouching(Wall.class)) setLocation(x, y);

In order for an object to not pass through an object of any kind you, it needs to receive the equal to opposite amount of force. This would be placed in the same area that the movement code is for each direction possible (or you can use a boolean to switch the values to add a bounce affect if it's an AI/Enemy).
If you want to make a position in the world a wall however instead of using a class then just tell me and I'll mock some code up.
//Reference
Actor ActorName = getOneIntersectingObject(ActorName.class);
if (ActorName != null) // Checks if the Player/Enemy is touching the wall
setLocation(getX(), getY()); //Change to the opposite of the regular speed (i.e. getX + 6 turns into getX - 6)
//Example IF Wall is above (this piece of code goes into the same method allowing the actor to move in the first place)
Actor Wall = getOneIntersectingObject(Wall.class);
if (Wall != null)
setLocation(getX(), getY() + Speed); //Speed can be a Variable or straight integer (number)
//Example IF It's an AI/Enemy (assumes movement is set in a method and assume bounce is only up and down)
private boolean Bounced = false;
...
if (Bounced == false) //Moving up
{
setLocation(getX(), getY() - Speed);
Actor Wall = getOneIntersectingObject(Wall.class);
if (Wall != null)
Bounced = true;
}
else //Moving Down
{
setLocation(getX(), getY() + Speed);
Actor Wall = getOneIntersectingObject(Wall.class); //can be replaced to check for Y = 0;
if (Wall != null)
Bounced = false;
}
