I have a series of strings in the following format: String a = Agregator

I have a series of strings in the following format: 

String a = "Agregator par. L1-23 2/22.-------->EFM Actelis ML628  8-210  alternative 8-/208                                                        ";

As you can see, the original format doesn’t look very good, so I would like to remove parts of the string to give the following result:

"Agregator par. L1-23 2/22.EFM Actelis ML628  8-210  alternative 8-/208"

Not all of my strings follow this exact format, however, which means they’re not simple to manipulate.

Here’s what I want to do:

  • Remove all trailing blank spaces (about 56 of them, but not always the same number)
  • Remove all occurrences of -------->, without removing hyphens from other parts of the string. The number of hyphens in --------> may vary between strings

    You can use regular expression to remove unwanted letters.

    String a= "Agregator par. L1-23 2/22.-------->EFM Actelis ML628  8-210  alternative 8-/208                                                        ";

     a = a.trim().replaceAll(" +", " ");
     a = a.replaceAll("-*>", " ");

    a.trim().replaceAll(" +", " ") will remove all spaces at end and if more than one spaces are there it will replace by single space.

    Output : "Agregator par. L1-23 2/22. EFM Actelis ML628 8-210 alternative 8-/208"
