Redundant 'else'

Reports redundant else keywords in if—else statements and statement chains.

The else keyword is redundant when all previous branches end with a return, throw, break, or continue statement. In this case, the statements from the else branch can be placed after the if statement, and the else keyword can be removed.

Example:

  if (name == null) {
      throw new IllegalArgumentException();
  } else {
      System.out.println(name);
  }

After the quick-fix is applied:

  if (name == null) {
      throw new IllegalArgumentException();
  }
  System.out.println(name);
