解析时到达文件末尾但没有丢失的大括号

Question

因此，当我编译此程序时，java会给出一条错误消息：解析时到达文件末尾 公共类MohoscopeEngine实现了HoroscopeEngine {                                                         ^

//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课程，我检查了每个支架和支架，发现没有错。为什么会出现问题以及我该如何解决？
