java - Simple switch in "for" loop and toLowerCase() method -


i beginner in java. making simple switch, in user entering number in words. training added "for" loop.

package javaexc; import java.util.scanner;  public class javastart {  public static void main(string[] args) {     scanner sck = new scanner(system.in);     system.out.println("type loop counter ");      int counter = sck.nextint();      system.out.println("counter is: " + counter );       (int = 0; <= counter; i++) {           system.out.println("type number in words");         string ch = sck.nextline();          switch (ch.tolowercase()) {               case "one":                 system.out.println("choice 1");                 break;             case "two":                 system.out.println("choice 2");                 break;             case "three":                 system.out.println("choice 3");                 break;             case "four":                 system.out.println("choice 4");                 break;             case "five":                 system.out.println("choice 5");                 break;              default:                 system.out.println("wrong data");                 break;          }          system.out.println("loops left:\n " + counter--);     }     system.out.println("end of switch");   }}

here result:

type loop counter  5 counter is: 5 type number in words wrong data                   // ?? loops left: 5 type number in words 1 choice 1 loops left: 4 type number in words 3                        // should ok, wrong here? wrong data loops left: 3 end of switch                //to break loop think  process finished exit code 0

my questions are: why first loop make default code? should make 2 scanners? 1 take value counter , second switch? why counter , numbers in words not working properly?

i know can tables etc. generally, purpose of program test "tolowercase()" method.

you're checking string in lower case ("three") against upper case ("three"). make sure they're both identical , shouldn't fail.
