Duplicate branches in 'switch'

Reports switch statements or expressions that contain the same code in different branches and suggests merging the duplicate branches.

Example:

switch (n) {
  case 1:
    System.out.println(n);
    break;
  case 2:
    System.out.println(n);
    break;
  default:
    System.out.println("default");
}

After the quick-fix is applied:

switch (n) {
  case 1:
  case 2:
    System.out.println(n);
    break;
  default:
    System.out.println("default");
}
