Exception in thread "Animation Thread" java.lang.NullPointerException

Here is the original code

import ddf.minim.spi.*;

import ddf.minim.signals.*;

import ddf.minim.*;

import ddf.minim.analysis.*;

import ddf.minim.ugens.*;

import ddf.minim.effects.*;

{PImage img0, img1, img2, img3, img4, img5, img6, img7;

img0= loadImage("cave.png");

img1 = loadImage("cave1.png");

img2 = loadImage("cave2.png");

img3 = loadImage("cave3.png");

img4 = loadImage("cave4.png");

img5 = loadImage("cavet1.png");

img6 = loadImage("cavet2.png");

img7 = loadImage("dirtcave2.png");}

Minim minim;

AudioPlayer player;

String[] tileMap;

int TILE_SIZE = 16;

PImage[] tiles = new PImage[8];

void setup(){

minim = new Minim(player);

player= minim.loadFile(dataPath("cavesound1.wav"));

player.play();

tileMap = loadStrings("tilemap1.txt");

size(TILE_SIZE*tileMap[0].length(), TILE_SIZE*tileMap.length);

tiles[0]=loadImage("dirt.png");

tiles[1]=loadImage("cave.png");

tiles[2]=loadImage("cave1.png");

tiles[3]=loadImage("cave2.png");

tiles[4]=loadImage("cave3.png");

tiles[5]=loadImage("cave4.png");

tiles[6]=loadImage("cavet1.png");

tiles[7]=loadImage("cavet2.png");

println(tileMap);

}

void draw(){

for(int i=0; i<tileMap.length;i++){

for(int j=0; j<tileMap[i].length();j++){

int tileValue=Character.getNumericValue(tileMap[i].charAt(j));

image(tiles[tileValue], j*TILE_SIZE,i*TILE_SIZE,TILE_SIZE,TILE_SIZE);

}}}

void stop(){

minim.stop();

player.close();

super.stop();

}

I have highlighted the area where the error occurs. any advice or help would be greatly appreciated.
