2D Platformer in Java. Loading level not working -

so, made platformer game. uses multiple levels.

public void switchlevel() {     clearlevel();     cam.setx(0);     try {         bufferedimage currentlevel = loader.loadimage("/level" + string.valueof(game.level + 1) + ".png");         loadimagelevel(currentlevel);         system.out.println("loaded level " + (game.level+1));     } catch (exception e) {         system.out.println("level " + string.valueof(game.level + 1) + " not found!");     }     game.level++; } 

this function switching levels. whenever has switch level 3 4 loads level. happens on level 4.

edit: method gets called when player collides flag object.

this part of collision method:

case flag: {                 if (getbounds().intersects(tempobject.getbounds())) {                     handler.switchlevel();                 }                 break;             }
