Question

我写了一个功能，它自称的次数是应该的3倍。我在程序中调用了一次，但总共执行了4次。任何人都可以解释我的问题吗？

 public static String[] MainBooker(Document doc, int counter){
            System.out.println("test");
            Queue<String> mainbooker = new LinkedList<String>();
            Elements span = doc.select("td");
            for(int i = counter+1 ; i < counter +21; i++){
                String inf = span.eq(i).text();
                if(counter%2 == 0 && i%2 == 0){
                    if(!inf.equals("")){
                        if(inf.contains("'"))
                            inf = inf.replaceAll("'", "\'");
                        mainbooker.add(inf);
                    }
                }
                else if(counter%2 != 0 && i%2 != 0){
                    if(!inf.equals("")){
                        if(inf.contains("'"))
                            inf = inf.replaceAll("'", "\'");
                        mainbooker.add(inf);
                    }
                }
            }         

            String[] mainbooker_info = new String[mainbooker.size()];

            int i = 0;
            for (String info : mainbooker) {
                mainbooker_info[i] = info;
                writeToFile(mainbooker_info[i]);
                i++;
            }  
            //Stack:
            //M/V || firstname || middleName || lastName || DoB 
            // Zipcode+ number || street || country || phonenumber || email
            return mainbooker_info;
    }

我在if语句中调用它：

else if(inf.contains("Main booker") ||  inf.contains("Haupt-Bucher") || inf.contains("Hoofdboeker")){  
                String[] result = MainBooker(doc, i);  
                if(!result[2].equals("-")){              
                    informationBasic.add(result[1] +" "+result[2]+ " "+ result[3]);
                }
                else if(result[2].equals("-")){
                    informationBasic.add(result[1] + " "+ result[3]);
                }
                mainbooker.addAll(Arrays.asList(MainBooker(doc, i)));
            }

在您的代码中，

else if(inf.contains("Main booker") ||  inf.contains("Haupt-Bucher") || inf.contains("Hoofdboeker")){  
            if(!MainBooker(doc, i)[2].equals("-")){              
                informationBasic.add(MainBooker(doc, i)[1] +" "+MainBooker(doc, i)[2]+ " "+ MainBooker(doc, i)[3]);
            }
            else if(MainBooker(doc, i)[2].equals("-")){
                informationBasic.add(MainBooker(doc, i)[1] + " "+ MainBooker(doc, i)[3]);
            }
            mainbooker.addAll(Arrays.asList(MainBooker(doc, i)));
        }

MainBooker已多次通话。试试这个：

else if(inf.contains("Main booker") ||  inf.contains("Haupt-Bucher") || inf.contains("Hoofdboeker")){
String[] result = MainBooker(doc, i);  
if(!result[2].equals("-")){              
    informationBasic.add(result[1] +" "+result[2]+ " "+ result[3]);
}
else if(result[2].equals("-")){
    informationBasic.add(result[1] + " "+ result[3]);
}
mainbooker.addAll(Arrays.asList(result));}

函数多次调用自己
