Loop printing twice java -

i have no idea why loop printing twice. have 2 separate classes have created , whatever reason cannot figure out why it's printing twice console. not sure if because called wrong in tabletest? or if had done wrong elsewhere. have run both in ide , command line , i'm still getting same issue.

public class tabletest { public static void main(string[] args){       int getbegin, getend;           system.out.println("enter number start with: ");         scanner input = new scanner(system.in);         getbegin = input.nextint();             while (getbegin < 0){                 system.out.println("please enter number greater 0.");                 getbegin = input.nextint();             }         system.out.println("enter number end with: ");         getend = input.nextint();             while (getend < 0 || getend < getbegin){                 system.out.println("please enter number greater 0. or greater first input.");                 getend = input.nextint();     }          multiplicationtable loop = new multiplicationtable(getbegin, getend);          loop.printtable(getbegin, getend);      } }      public class multiplicationtable {  public multiplicationtable(int begin, int end){     printtable(begin,end); }  void printtable(int begin, int end){      system.out.println(string.format("%-10s %-10s %-10s", "number", "squared" , "cubed"));      (int = begin; <= end; ++i){         system.out.println(string.format("%-10s %-10s %-10s", i, i* i, i*i*i));     }  }  } 

your constructor in multiplicationtable calls printtable method , call again in main method
