java - 解析时到达文件末尾，但没有缺少大括号

Question

所以当我编译这个程序时，java给出了一个错误消息：在解析公共类MohoscopeEngine实现HoroscopeEngine时到达文件末尾{ ^

//MohoscopeEngine.java


public class MohoscopeEngine implements HoroscopeEngine{

final String[] constant ={"Bring your friends from ", "and ", "to go to party at "};

String[] fiveplaces = {"Rocky", "Safford", "Chapin", "Art Museum", "Mead"};





/** generate random index for array without repeating*/
public String randomIndex(){
    int index = (int)(Math.floor(Math.random()*5));
    return fiveplaces[index];
}





public String getHoroscope(){

    //for(int i =0; i < index.length; i++)
    String mohoscope = constant[0] + randomIndex() + constant[1] + randomIndex() + constant[2] + randomIndex();
    return mohoscope;
}
}

我不认为我没有附上班级，我检查了每个支架和大括号，没有发现任何问题。为什么会出现问题，我应该如何解决？
