I am looping through a list to extract data point, but would like to know when I am on the last element (a certain function that is run in the for loop should not be run when its the last element)

  for(final eachLine in _blocks){
    //
    _finalString = _finalString   eachLine   '\n';
  }

(I don't want to add \n) for the very last element, so I'd like to know when I'm on the very last element if its possible?

CodePudding user response：

There is no such way to do this with for-in/forEach style loop. Either use an iterator, a for loop with an index, or for this specific case you can use the String.join method:

var _finalString = _blocks.join('\n')
