foreach变量导致“<identifier> 预期的“编译错误</identifier>

Question

I am working on a homework assignment for an Intro to Java class. When I try and compile my code I am getting a compilation error. I am sure it is something simple, but I cannot figure out the cause of the error.

Note, the errors I am receiving are under the source code.

  // Declarations
  final String QUESTIONS[] = new String{"Please input your answer using A, B, or C.\nWho is the coolest guy ever? \n\nA. Max\nB. James Bond\nC. Burt Reynolds", "Please input your answer using A, B, or C.\nWho do coolguys' drive?\n\nA. Datuns\nB. Panters\nC. Porsches", "Please input your answer using A, B, or C.\nWhat is the coolest city?\n\nA. Los Angles\nB. Denver\nC.Boulder"};
  final String CONGRATS = "You got it right!"
  final string FAIL = "Horribly. Horribly wrong. =["
  final String ANSWERS[] = new String{"A","A","A"};
  final String QUIT = "QUIT";
  String tempanswer[] = new String[3]
  int index;
  int index2;
  String keeplaying;


  Output "Would you like to play?"
  input keeplaying
  if(keepplaying == QUIT) {
  return;
  } else {
    for(index = 0; index<QUESTIONS.length; index++) {
    Output QUESTIONS[index]
    input tempanswer[index];
      for(index2 = 0; index2<ANSWERS.length; index2++) {
        if tempanswer == ANSWERS[index2] {
        output CONGRATS } else { output FAIL }
      }
    }
  }

  return;
  } else {
    for(index = 0; index<QUESTIONS.length; index++) {
    System.out.println(QUESTIONS[index]);
    JOptionPane.showInputDialog(tempanswer[index]);
      for(index2 = 0; index2<ANSWERS.length; index2++) {
        if(tempanswer == ANSWERS[index2]) {
        System.out.println("You got question " . index2 . " correct!");} else { System.out.println("You got question " . index2 . " incorrect.");}
      }
    }
  }

  System.exit(0);
  }
}

These are the errors I get on compile

FunQuiz.java:57: <identifier> expected
        System.out.println("You got question " . index2 . " correct!");} else { System.out.println("You got question " . index2 . " incorrect.");}
                                                         ^
FunQuiz.java:57: ';' expected
        System.out.println("You got question " . index2 . " correct!");} else { System.out.println("You got question " . index2 . " incorrect.");}

Answer 1

Use System.out.println("You got question " + index2 + " correct;");} instead of

System.out.println("You got question " . index2 . " correct!");};

Java uses + for concatenation.

Answer 2

In JAVA the concatenation simbol is not "." but "+".
Use System.out.println("You got question " + index2 + " correct;");}
