else if in Android Studio

I am trying to run my app but I cant because it doesn't accept my code.@Override public boolean onNavigationItemSelected(@NonNull MenuItem menuItem) { if (menuItem.getItemId() == R.id.action_home) fragment = new HomeFragment(); else if (menuItem.getItemId() == R.id.action_procedures); fragment = new ProceduresFragment(); else if (menuItem.getItemId() == R.id.action_map); fragment = new ProceduresFragment(); return loadFragment(fragment);
