Follow DRY principle-CodePudding

I have an implementation of following kind-

int max_count = 10;

main() {

  Writer writer = //initialise writer;
  List records = new ArrayList();

  while(true) {

    // some functionality
    // some functionality

    if (records.size() >= max_count) {

      // xyz code
      // xyz code

      records = new ArrayList();
    }
  }

  if(records.size() != 0) {

    // xyz code
    // xyz code
  }

}

How can I follow the DRY principle here so that the code in while loop and in if block shortens?

CodePudding user response：

You simple have to create another function that contains yout "xyz code" and call it where needed. I hope this answer is what you wanted, if this is not or if you need anything else, feel free to ask !
Have a great day, Lukas.

I guess the most simple way would be extracting the xyz code to one function and call it multiple times.

int max_count = 10;

void doXyz(){
      // xyz code
      // xyz code
}

main() {

  Writer writer = //initialise writer;
  List records = new ArrayList();

  while(true) {

    // some functionality
    // some functionality

    if (records.size() >= max_count) {

      doXyz()

      records = new ArrayList();
    }
  }

  if(records.size() != 0) {

    doXyz()
  }

}
