将Runnable实现到接口的抽象类(Abstract class that implements Runnable into interface)

 如何将实现Runnable的抽象类重构为接口？  
import com.codahale.metrics.health.HealthCheck;

public abstract class ApplicationProcessor implements Runnable {

    public abstract HealthCheck getHealthCheck();
}
 
 更新：以及如何在将来删除通用通配符类型的使用？  
import io.dropwizard.lifecycle.Managed;
import java.util.concurrent.Future;
import com.codahale.metrics.health.HealthCheck;

public class ManagedBean extends HealthCheck implements Managed {

    private final String name;
    private final ManagedThreadPool threadPool;
    private final ApplicationProcessor processor;
    private Future<?> future; // HERE sonarqube complains..

    public ManagedBean( String name, ManagedThreadPool threadPool, ApplicationProcessor processor ) {
        this.name = name;
        this.threadPool = threadPool;
        this.processor = processor;
    }

    @Override
    public void start() throws Exception {
        future = threadPool.submit( processor );
    }

    @Override
    public void stop() throws Exception {
        if ( !future.isDone() ) {
            future.cancel( true );
        }
    }

    @Override
    protected Result check() throws Exception {
        return processor.getHealthCheck().execute();
    }

}
 
 谢谢 

How can I refactor an abstract class that implements Runnable into an interface? 
import com.codahale.metrics.health.HealthCheck;

public abstract class ApplicationProcessor implements Runnable {

    public abstract HealthCheck getHealthCheck();
}
 
UPDATE: And also how can I remove the usage of a generic wildcard type for the future? 
import io.dropwizard.lifecycle.Managed;
import java.util.concurrent.Future;
import com.codahale.metrics.health.HealthCheck;

public class ManagedBean extends HealthCheck implements Managed {

    private final String name;
    private final ManagedThreadPool threadPool;
    private final ApplicationProcessor processor;
    private Future<?> future; // HERE sonarqube complains..

    public ManagedBean( String name, ManagedThreadPool threadPool, ApplicationProcessor processor ) {
        this.name = name;
        this.threadPool = threadPool;
        this.processor = processor;
    }

    @Override
    public void start() throws Exception {
        future = threadPool.submit( processor );
    }

    @Override
    public void stop() throws Exception {
        if ( !future.isDone() ) {
            future.cancel( true );
        }
    }

    @Override
    protected Result check() throws Exception {
        return processor.getHealthCheck().execute();
    }

}
 
Thanks

 注意 ：我已经用非常小的一段数据测试过了。试试看，如果你卡住了，就让我知道。 我们会从那里拿走它。  
 假设我们的数据看起来像这样  
   
 现在我们运行这个代码  
Sub Sample()
    Dim oSht As Worksheet
    Dim arr As Variant, FinalArr() As String
    Dim i As Long, j As Long, k As Long, LRow As Long

    Set oSht = ActiveSheet

    With oSht
        LRow = .Range("A" & .Rows.Count).End(xlUp).Row

        arr = .Range("A2:H" & LRow).Value

        i = Application.WorksheetFunction.CountA(.Range("G:H"))

        '~~> Defining the final output array
        ReDim Preserve FinalArr(1 To (LRow + i - 3), 1 To 6)

        k = 0
        For i = LBound(arr) To UBound(arr)
            k = k + 1
            FinalArr(k, 1) = arr(i, 1)
            FinalArr(k, 2) = arr(i, 2)
            FinalArr(k, 3) = arr(i, 3)
            FinalArr(k, 4) = arr(i, 4)
            FinalArr(k, 5) = arr(i, 5)
            If arr(i, 6) <> "" Then FinalArr(k, 6) = arr(i, 6)

            For j = 7 To 8
                If arr(i, j) <> "" Then
                    k = k + 1
                    FinalArr(k, 1) = arr(i, 1)
                    FinalArr(k, 2) = arr(i, 2)
                    FinalArr(k, 3) = arr(i, 3)
                    FinalArr(k, 4) = arr(i, 4)
                    FinalArr(k, 5) = arr(i, 5)
                    FinalArr(k, 6) = arr(i, j)
                End If
            Next j
        Next i

        .Rows("2:" & .Rows.Count).Clear

        .Range("A2").Resize(UBound(FinalArr), 6).Value = FinalArr
    End With
End Sub
 
 产量  
  

Note: I have tested this with very small piece of data.. Give it a try and if you are stuck then let me know. We will take it from there. 
Let's say our data looks like this 
 
Now we run this code 
Sub Sample()
    Dim oSht As Worksheet
    Dim arr As Variant, FinalArr() As String
    Dim i As Long, j As Long, k As Long, LRow As Long

    Set oSht = ActiveSheet

    With oSht
        LRow = .Range("A" & .Rows.Count).End(xlUp).Row

        arr = .Range("A2:H" & LRow).Value

        i = Application.WorksheetFunction.CountA(.Range("G:H"))

        '~~> Defining the final output array
        ReDim Preserve FinalArr(1 To (LRow + i - 3), 1 To 6)

        k = 0
        For i = LBound(arr) To UBound(arr)
            k = k + 1
            FinalArr(k, 1) = arr(i, 1)
            FinalArr(k, 2) = arr(i, 2)
            FinalArr(k, 3) = arr(i, 3)
            FinalArr(k, 4) = arr(i, 4)
            FinalArr(k, 5) = arr(i, 5)
            If arr(i, 6) <> "" Then FinalArr(k, 6) = arr(i, 6)

            For j = 7 To 8
                If arr(i, j) <> "" Then
                    k = k + 1
                    FinalArr(k, 1) = arr(i, 1)
                    FinalArr(k, 2) = arr(i, 2)
                    FinalArr(k, 3) = arr(i, 3)
                    FinalArr(k, 4) = arr(i, 4)
                    FinalArr(k, 5) = arr(i, 5)
                    FinalArr(k, 6) = arr(i, j)
                End If
            Next j
        Next i

        .Rows("2:" & .Rows.Count).Clear

        .Range("A2").Resize(UBound(FinalArr), 6).Value = FinalArr
    End With
End Sub
 
Output
