string - Java Weekday input Validation -

-

is there "tidier" way of writing code? i'm stickler simplicity , seems bit repetitive me. (i'm changing days numbers can use them in own if statements, if wondering) suggestions?

scanner scantext = new scanner(system.in);  system.out.print("enter day: "); string weekday = scantext.nextline();  int day = 0;  if (weekday.equalsignorcase("monday"))   day = 1; else if (weekday.equalsignorcase("tuesday"))   day = 2; else if (weekday.equalsignorcase("wednesday"))   day = 3; else if (weekday.equalsignorcase("thursday"))   day = 4; else if (weekday.equalsignorcase("friday"))   day = 5; else if (weekday.equalsignorcase("saturday"))   day = 6; else if (weekday.equalsignorcase("sunday"))   day = 7; else {   system.out.print("error! invalid day: ");   weekday = scantext.nextline(); }

if not using jdk 1.8, code may you:

     list<string> strdays = arrays.aslist("monday", "tuesday", "wednesday", "thusday", "friday", "saturday", "sunday" );       string weekday = scantext.nextline();       int day = 0;      if(strdays.contains(weekday)) {           day = strdays.indexof(weekday) + 1;      } else {          system.out.print("error! invalid day: ");          weekday = scantext.nextline();      }
