Using "this" operator but method does not reassign values
Program sets strings to a random index of the array list. The issue is that when the randomizeSlotsStrings method is called, it does not reassign the string values, it just returns null.
private String slot1,slot2,slot3; public static ArrayList<String> slots = new ArrayList<String>(5); public static void initSlots(){ slots.add("BAR"); slots.add("WILD"); slots.add("7RED"); slots.add("7WHITE"); slots.add("CHERRY"); } public String getSlots(){ this.slot1 = slot1; this.slot2 = slot2; this.slot3 = slot3; return slot1 + slot2 + slot3; } public void randomizeSlotStrings() { slot1 = slots.get((int)Math.random(5)); slot2 = slots.get((int)Math.random(5)); slot3 = slots.get((int)Math.random(5)); } public static void main(){ initSlots(); randomizeSlots(); system.out.println(getSlot()); } Expected output examples> "BAR","WILD","7RED" Actual output > null, null, null
