如何在其他Java類中將變量存儲在字符串中？

Question

爲了組織目的，我想在一個單獨的類（Constants.java）中存儲一系列「字符串」。

Constants.java：

public static final String qualification1 = "'Priority' = \"" + priority + "\" AND 'Status' = \"In Progress\" AND 'Assignee' = \"" + assigneeInput + "\""; 
... 

在我的主應用程序類，我想從上面

Main.java調用這些：

// Examples to show that these variables are dynamic 
String assigneeInput = soapResponseAssignee.getSOAPBody().getTextContent(); 
String[] priorityList = {"Low", "Medium", "High", "Critical"}; 

for (String priority : priorityList) { 
    String qualification = RemedyConstants.qualification1; 
    String qualification = RemedyConstants.qualification2; 
    String qualification = RemedyConstants.qualification3; 
    ... 
} 

問題是提供給我的主類的字符串往往有變量，即01在那裏定義的或assigneeInput。如果我將字符串存儲在其他地方，即Constants.java，我實際上不會使用我想要的字符串。如何提供我想要的字符串，同時在適當的上下文中引用這些變量？

Answer 1

使用字符串格式

public static final String qualification1 = "'Priority' = \"%s\" AND 'Status' = \"In Progress\" AND 'Assignee' = \"%s\""; 

然後，當你想使用它

String.format(qualification1, "Low", "Alice"); 

或添加功能到你的類做格式

String getQualification1(String priority, String assignee) { 
    return String.format(qualification1, priority, assignee); 
} 

Answer 2

這很簡單。不知道爲什麼它沒有點擊開始，我可以把字符串作爲一個對象的屬性...

Main.java：

String qualification = RemedyConstants.getQualification1(priority, assigneeInput); 

Constants.java：

public static String getQualification1(String priority, String assigneeInput) { 
     return "'Priority' = \"" + priority + "\" AND 'Status' = \"In Progress\" AND 'Assignee' = \"" + assigneeInput + "\""; 
    }
