关于增强for循环的使用

class MultipleQUestion extends Question{   //多选题类
    
    private char[] answer;   //多选题答案属性
    
    public char[] getAnswer() {
        return answer;
    }

    public void setAnswer(char[] answer) {
        this.answer = answer;
    }

    MultipleQUestion(char[] answer,String title,String[] options){     //多选题构造函数
        
        super(title,options);
        this.setTitle(title);
        this.setOptions(options);
        this.answer = answer;
        
    }
    
    @Override
    public boolean check(char[] answer){  //多选题检查答案方法
        Arrays.sort(answer);
        if(this.answer.length == answer.length){
            for(int i =0;i<answer.length;i++){       // 此处不能用增强for循环for(int i : answer)遍历answer，i不是char类型的元素，若用for(char i : answer)遍历，则只能用来打印，不能用来做数组下标去比较
                if(this.answer[i] != answer[i]){
                    return false;
                }
            }
            return true;
        }
        return false;
    }
}
