Why are variables not local in case statements?
<p>I recently add another menu item to an android java app and was suprised that Eclipse said that variable from the previous case:break were not local (So I've just added a suffix to get by).</p>

<p>I'm a bit confused as in my mind, the 1st set of case:break would not be executed at all if the 2nd option was chosen.  Could someone explain my faulty thinking please?</p>

<pre><code>        case R.id.menuDebugMode:
            debugMode = !debugMode;
            if (debugMode){
                Toast.makeText(mainActivity.this, "Debug Mode on - NOT TO BE USED WHILST DRIVING", Toast.LENGTH_LONG).show();           
            } else {
                tvDebug.setText("");
                tvInfo.setText("");
            }
            SharedPreferences settings = getSharedPreferences(PREFS_NAME, 0);
            SharedPreferences.Editor editor = settings.edit();
            editor.putBoolean("debugMode", debugMode);
            editor.commit();
        break;

        case R.id.menuSpeedMode:
            speedSignMode = !speedSignMode;
            if (speedSignMode){
                Toast.makeText(mainActivity.this, "SpeedSign Mode in use", Toast.LENGTH_LONG).show();           

            } else {
                    Toast.makeText(mainActivity.this, "MapSpeed Mode in use", Toast.LENGTH_LONG).show();            
            }
            SharedPreferences settings2 = getSharedPreferences(PREFS_NAME, 0);
            SharedPreferences.Editor editor2 = settings2.edit();
            editor2.putBoolean("speedSignMode", speedSignMode);
            editor2.commit();
        break;`
