DefaultNotLastCaseInSwitch

Reports switch statements or expressions in which the default branch is positioned before another case. Such a construct is unnecessarily confusing. A quick-fix is provided to move the default branch to the last position, if possible.

Example:

switch (n) {
      default:
          System.out.println();
          break;
      case 1:
          break;
  }

After the quick-fix is applied:

switch (n) {
    case 1:
        break;
    default:
        System.out.println();
        break;
  }
