Explanation / Answer

Answer

I tried my best

if(m.getMap(x, y).equals("C")){
g.drawImage(m.getCheese(), x * 32, y * 32, null);
}
if(m.getMap(x, y).equals("G")){
g.drawImage(m.getGround(), x * 32, y * 32, null);
}
if(m.getMap(x, y).equals("W")){
g.drawImage(m.getWall(), x * 32, y * 32, null);
}
   change the above lines of code to

if(m.getMap(x, y).equals("C")){
g.drawImage(m.getCheese(), x * 64, y * 64, null);
}
if(m.getMap(x, y).equals("G")){
g.drawImage(m.getGround(), x * 64, y * 64, null);
}
if(m.getMap(x, y).equals("W")){
g.drawImage(m.getWall(), x * 64, y * 64, null);
}
