匹配的字符串不会在 if else 条件 java 中通过语句

Question

我正在尝试使用数据库计数来验证固定长度文件计数，当它与计数匹配时，pass 语句不会在 if 语句中执行，但是它会转到 else 语句。任何方向都将适用。

以下是我的代码：

static String ubservicesCount = "";

    String connectionUrl = "jdbc:sqlserver://"+strpServer+":"+strpPort+";databaseName="+strpDatabase+";IntegratedSecurity=true";

                // Declare the JDBC objects.  
                Connection con = null;  
                Statement stmt = null;  
                ResultSet rs = null;  

                Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");  
                con = DriverManager.getConnection(connectionUrl); 

                String SQL = strpQuery5+Qt+ProcessID+Qt;
                stmt = con.createStatement();  
                rs = stmt.executeQuery(SQL);  

                while (rs.next()) {
                    ubservicesCount = rs.getString(1);
                    System.out.println("UB servicesCount is " +ubservicesCount);
                }

                String st;
                BufferedReader Br = null;
                File objFile = new File(strPlanFile+NewFileNmae);
                Br = new BufferedReader(new FileReader(objFile));

                List<String> list = new ArrayList<String>();
                while ((st = Br.readLine()) != null) {

                    String arraylist = st;              

                    String RcdType = arraylist.substring(0, arraylist.length()-392);

                    list.add(RcdType);          

                }

                Set<String> unique = new HashSet<String>(list);
                for (String key : unique) {


                    if(key.trim().toString().equals("SALINE")){

                        System.out.println(key + ": " + Collections.frequency(list, key));

                        int fileCount = Collections.frequency(list, key);

                        if(ubservicesCount.trim().toString().equals(fileCount))

                            objReport.setValidationMessageInReport("PASS", "Flat File "+key+" count "+fileCount+" is Matched with Database ubdiagcodes Count "+ubservicesCount);                                                                  
                        else
                        {
                            objReport.setValidationMessageInReport("FAIL", "Flat File "+key+" count "+fileCount+" is not Matched with Database ubdiagcodes Count "+ubservicesCount);                

                        }                       
                    }                               
                }

                Br.close();

执行后在我报告的else语句中打印失败。我调试了我可以在比较语句中看到它与计数匹配的地方。我不确定我在这里遗漏了什么。

试试这个

if(ubservicesCount.trim().toString().equalsIgnoreCase(String.ValueOf(fileCount)))

我认为问题在于您正在使用 .equals 并将字符串对象与整数进行比较...

即

布尔值java.lang.String.equals(Object anObject)

Compares this string to the specified object. The result is true if and only if the argument is not null and is a String object that represents the same sequence of characters as this object.

匹配的字符串不会在 if else 条件 java 中通过语句

Matched String is not going to Pass statement in the if else condition java

java

if-statement

flat-file
