Tiled in Slick2D

Hello guys, I’m new to this forum and I need some help :/…
So my question is, is there any way I could make that one whole layer in tiled map editor is blocked…So when player tries to move he has to check if left tile right tile,upper tile and bottom tile is on the blocked layer if it is he isn’t able to move…Here’s my code:

package javagame;
       import org.lwjgl.input.Mouse;
       import org.newdawn.slick.*;
       import org.newdawn.slick.state.*;
       import org.newdawn.slick.tiled.TiledMap;




       public class Play extends BasicGameState{
	   Animation Hero, movingUp, movingDown, movingLeft, movingRight,standingfront;
	   private String spriteName = "Heroj";//string above the player
	   private TiledMap tileMap1;//tiled map
	   int[] duration = {100,100,100,100};//duration for how long is animation going to last
	   public String mouse = "1";//just for mouse position variable
       int spritePosisionX=0;//map position, and also for moving player(changed only for map pos)
	   int spritePosisionY=0;//map position, and also for moving player(changed only for map pos)
	   float shiftX = spritePosisionX + 220;//player's starting position X(and for moving)
	   float shiftY = spritePosisionY + 200;//player's starting position Y(and for moving)
       //	private Music music; //music(that's for background)
	   private int coveringSpriteLayer;
	   private int backgroundLayer;
	   private int blockedLayer;
	   private int grassLayer;
	   private int waterLayer;

	   //constructor
