java - Switch statement not acting correctly -

i'm trying switch statement work.

i ask user's birthday , put in format dd.mm.yyyy. if statement determines if use "." separate or 1 of other symbols such "/", " ". other symbols work fine, enter switch statement if user enters 15/07/1993 work fine , month becomes july. when enter 15.07.1993 goes default case not 7th case.

i assume has got escaped "."

("\\.") 

this might changing value of it. there way around it? input scanner.

any questions feel free ask.

if(input.contains("\\.")) {     string[] tokens = input.split("\\.");     day = integer.parseint(tokens[0]);     intmonth = integer.parseint(tokens[1]);     year = integer.parseint(tokens[2]); }  switch(intmonth)     {            case 1: month = "january";         break;       case 2: month = "febuary";         break;     case 3: month = "march";         break;     case 4: month = "april";         break;     case 5: month = "may";         break;     case 6: month = "june";         break;     case 7: month = "july";         break;     case 8: month = "august";         break;     case 9: month = "september";         break;     case 10: month = "october";         break;     case 11: month = "november";         break;     case 12: month = "december";         break;       default: month = "not valid";         break;               } 

the problem use regular expression string.contains.

according method documentation, need supply charsequence string.contains, ie. have write if (input.contains(".")) instead of if (input.contains("\\.")).
