java - 如何在另一个 Java 类中存储带有变量的字符串？

Question

为了组织目的，我想在一个单独的类(Constants.java)中存储一系列“字符串”。

Constants.java:

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

在我的主应用程序类中，我想从上面调用这些

Main.java:

// 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;
    ...
}

问题是提供给我的 Main 类的字符串往往包含变量，即 priority 或 assigneeInput，它们是在那里定义的。如果我将字符串存储在其他地方，即 Constants.java，我实际上不会使用我想要的字符串。如何提供所需的字符串，同时在适当的上下文中引用这些变量？

Answer 1

使用字符串格式

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

然后当你想使用它时

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

或者将函数添加到执行格式的类中

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