[SOLVED]Saving and Loading

Newbie & Debugging Questions
#1

I am currently making a 2d game but there are some problems with saving and loading. Here is my saving methgod which works perfectly:

public static void PLAYER_AND_WORLD_DATA_SAVE() {
    FileWriter writer = null;

    for (int a = 0; a < 30; a++) {
        try {
            writer = new FileWriter("saves/PlayerAndWorld.sav");
			writer.write(Integer.toString(Game.world.x));
			writer.write(System.getProperty( "line.separator" ));
			writer.write(Integer.toString(Game.world.y));
			writer.write(System.getProperty( "line.separator" ));
			writer.write(Integer.toString(Game.world.type));
			writer.write(System.getProperty( "line.separator" ));
			writer.write(Integer.toString(Environment.hours));
			writer.write(System.getProperty( "line.separator" ));
			writer.write(Integer.toString(Environment.minutes));
			writer.write(System.getProperty( "line.separator" ));
			writer.write(Player.name);
			writer.write(System.getProperty( "line.separator" ));
			writer.write(Integer.toString(Player.money));
			writer.write(System.getProperty( "line.separator" ));
            
			writer.close();
            writer = null;
            
        } catch (IOException e) {
            e.printStackTrace();
            break;
        }
    }

    if (writer != null) { try { writer.close(); } catch (Exception e) {} }
}

However the following loading code doesnt work and hightlights underlines the words…(int)scanner.nextLine();

	public void PLAYER_AND_WORLD_DATA_LOAD() {
	    Scanner scanner = new Scanner("saves/PlayerAndWorld.sav");
	
		while (scanner.hasNextLine()) {
			Game.world.x = (int)scanner.nextLine();
		}
		scanner.close();
	}

The world.x is infact an integer and im tryting to convert the strings within the text document into an int so i can set the world.x to this number
