java - Program ignoring "If Else" and printing everything -

i'm trying create random number generator program tracks player's wins, losses, winning percentage , total winnings. logic of program player gets 3 chances per session , computer generates random number player needs guess or rather should match.

i've tried use if & else statements tell user if needs guess higher number or lower number within 3 allowed guesses. what's happening ignores conditions , prints 3 chances @ once , ends game.

any inputs on highly appreciated.

game class:

do {         try {             system.out.println("guess number between 1-100: ");             userguess = integer.parseint(scanner.nextline());             if (userguess < 1 || userguess > 100) {                 system.err.println("error : guess must between 1-100");             }         } catch (exception e) {             system.err.println("error : guess must between 1-100");         }      } while(userguess < 1 && userguess > 100);//incorrect  //correct condition -> while(userguess < 1 || userguess > 100);  

a number cannot less 1 , greater 100 @ same time.

edit 1 : in 2nd loop following 2 condition

1) if (userguess != compguess && (userguess <= (compguess + 5))             && (userguess >= (compguess - 5)))   2)else if (userguess != compguess) 

should evaluated if number of guesses player exceeds number of attempts, therefore 2 if conditions should written outside loop.

also need first while loop keep user input valid between 1-100, , second while loop inside it.

the final code this.

    {          {             try {                 system.out.println("guess number between 1-100: ");                 userguess = integer.parseint(sc.nextline());                 if (userguess < 1 || userguess > 100) {                     system.err                             .println("error : guess must between 1-100");                 }             } catch (exception e) {                 system.err                         .println("error : guess must between 1-100");             }         } while (userguess < 1 || userguess > 100);          system.out.println(" " + userguess);          if (userguess > compguess) {             system.out.println("your guess is: " + userguess                     + "and random number: " + compguess);             system.out.println("sorry, need go lower  :");          }         if (userguess < compguess) {             system.out.println("your guess is: " + userguess                     + "and random number: " + compguess);             system.out.println("sorry, need go higher  :");             system.out.println("if 1");         }         numattempts++;          if (userguess == compguess) {             system.out.println("lucky number : " + compguess                     + "your  guess : " + userguess);             system.out.println("congratulations won " + 10 + "$");             // player.setgameswon(1);             // player.settotalwinnings(10);          }      } while (userguess != compguess & numattempts < 3);      if (userguess != compguess && (userguess <= (compguess + 5))             || (userguess >= (compguess - 5))) {         system.out.println("lucky number : " + compguess                 + " final guess : " + userguess);         // system.out.println("congratulations won " + cnum + "$");         // player.settotalwinnings(5);      } else if (userguess != compguess) {         system.out.println("lucky number : " + compguess                 + "your  guess : " + userguess);         system.out.println("sorry better luck next time");         // player.setgameslost(1);         // player.settotalwinnings(-1);      }  }
