如何计算类中存在的字符串对象数

Question

我有一个具有字符串变量数量的类，我想计算所有字符串变量。

public class Account {
    
    //objects
//    private String pageAuthenticationNavBar = "xpath:=//div[@class='ng-binding' and contains(text(),'Account Authentication')]";
    private String listAuthMethod = "id:=account-authentication-authentication-methods";
    private String btnContinue = "xpath:=//button[@id='account-authentication-continue']";
    private String btnSkip = "xpath:=//*[contains(text(), 'Send OTP')]/..//*[contains(text(),'Skip')]";
    private String btnSkipNoSMS = "xpath:=//*[@class='skip-sms-auth-container']//*[contains(text(),'Skip Authentication')]";
    private String formAccountAuthentication = "xpath:=//*[@class='global-container authentication-process']";
    private String txtChooseSubscriber = "xpath:=//div[contains(text(), 'Choose Subscriber')]";
    private String txtSubscriberByIndex = "xpath:=(//*[contains(@class,'flex subscriber-item-inside-list')]//*[@class='subscriber-icon'])[INDEX]";
    private String btnSendOtp = "xpath:=//button[starts-with(@class,'auth-continue-button')]"; //id:=account-authentication-send-otp
    private String txtOtp = "id:=smsCodeInput";
}

是否有任何方法，有什么逻辑来计算所有字符串对象？

正如F1SH在评论中提到的那样，您可以使用以下反射：

public class Test{
 String a="";
 String b="";
 String c="";

 public static void main(String[] args) {
 
 int stringCount=0;
        for(Field f : Test.class.getDeclaredFields()) {
            if(f.getType().getName().equals("java.lang.String"))
                stringCount++;
        }
        System.out.println(stringCount);
}
}

输出：
