- 

import java.util.scanner;  public class main {  public static void main(string[] args) {      scanner input = new scanner(system.in);     system.out.println("enter name of favorite insect: ");     string userstring = input.next();      string lyric = "";     string endlyric = "";     string onethree = "i'm " +lyric+ "my baby " +userstring;     string 2 = "won't mommy proud of me";     int count = 5;      while (count != 0)     {          if (count == 5)         {              lyric = "bringing home ";             endlyric = "ouch!! stung me!!";             count = count - 1;          } else if (count == 4)         {             lyric = "squishin' ";             endlyric = "ick!! feel sick!!";             count = count - 1;          } else if (count == 3) {             lyric = "barfin ";             endlyric = "oh!! mess!!";             count = count - 1;         }          else if (count == 2)         {             lyric = "wipin' ";             endlyric = "oops!! mommy's new towel!!";             count = count - 1;         }          else if (count == 1)         {             lyric = "wringin' ";             endlyric = "bye-bye baby "+userstring+ "!!";             count = count - 1;         }          system.out.println(onethree);         system.out.println(two);         system.out.println(onethree);         system.out.println(endlyric);         system.out.println("");      }  } }

for odd reason lyric variable not print... error states unused. have initialized variable. other variables work fine 1 please help...

you not using lyric variable anywhere in code after assigning value. use before initialized non empty value.

string onethree = "i'm " +lyric+ "my baby " +userstring; become "i'm baby " +userstring;, since @ point it's assigned, lyric empty. fact change lyric later non empty doesn't make difference, since never access again after assignment.

you initialize onethree :

string onethree = "i'm {0} baby " +userstring;

and then, instead of system.out.println(onethree); system.out.println(string.format(onethree,lyric));. put current value of lyric in string.
