java – 抽象类或接口中的public static final字段

我有很多抽象类的子类,每个子类声明一个具有相同名称的公共静态final字段.我想在抽象超类中使用这个字段而不初始化它,并希望每个子类都被强制初始化它.

我正在考虑这个问题,因为抽象类的所有子类都声明了一个名为UNIQUE_ID的公共静态最终字符串字段,并且每个子类都必须声明具有该名称的字段.

我希望我的问题很清楚,如果不是,请告诉我.

可以或多或少地与此相提并论吗？

编辑：代码添加：

我的抽象类看起来像：

public abstract class ExperimentPanelModel extends Panelizable {
protected String nextButtonText;
protected String backButtonText;
protected String skipButtonText;
protected Properties currentFile;
protected List<Properties> pastFiles = new ArrayList<Properties>();

public ExperimentPanelModel(Properties argcurrentfile,List<Properties> argpastfiles) {
    currentFile = argcurrentfile;
    pastFiles = argpastfiles;
    nextButtonText = "Next";
    backButtonText = "Back";
    skipButtonText = "Skip";
}
...
}

该抽象类的一些非抽象子类看起来像(注意它们都声明了公共静态最终字符串UNIQUE_ID)：

public class ConfigurationGUI extends ExperimentPanelModel {

public static final String UNIQUE_ID = "ConfigurationGUI";
public static final String DATA_MODIFIED = "DataModified";

Date dateOfLastSession;
int ExperimentalSession;
int ExperimentOrder;

boolean nextButtonEnabled = false;

public ConfigurationGUI(Properties argcurrentfile,List<Properties> argpastfiles) {
    super(argcurrentfile,argpastfiles);
    nextButtonText = "Confirm";
    backButtonText = "Abort";
}

...
}

一个例子：

public class Introduction extends ExperimentPanelModel {

public static final String UNIQUE_ID = "Introduction";
public static final String INSTRUCTIONS_XML_FILE = "instructions.xml";
public static final String THIS_INSTRUCTION_PROPERTY = UNIQUE_ID;

private String thisInstructionText = UNIQUE_ID;

Properties readInstructionsproperties = new Properties();

public Introduction(Properties argcurrentfile,List<Properties> argpastfiles) {
 ...

最后一个：

public class Instruction1 extends ExperimentPanelModel {

public static final String UNIQUE_ID = "Instruction1";
public static final String INSTRUCTIONS_XML_FILE = "instructions.xml";
public static final String THIS_INSTRUCTION_PROPERTY = UNIQUE_ID;
...
}
