我需要将一个变量传递给excel表格单元格。所以如何检查它是否返回空值。如果它具有空值，我需要在单元格而不是实际单元格中给出警告消息值。

            // Element fetching 

                       Element= driver.findElement(By.xpath(".//*[@id='Form1']/table[3]/tbody/tr[5]/td[3]/a")) ;
                       Email_ID = Element.getText();

                   FileInputStream fis = new FileInputStream("E:\\ExcelRead.xls");
                        Workbook wb = WorkbookFactory.create(fis);
                        Sheet sh = wb.getSheet("Input");

        // File Handling
                        Row row = sh.createRow(ExcelRow);
            Cell cell_3 = row.createCell(2);
                        cell_3.setCellValue(Email_ID);

//文件处理

      FileOutputStream fos = new FileOutputStream("E:\\ExcelRead.xls");

                        wb.write(fos);

                        fos.close();

                        System.out.println("Excel File Written.");

检查它是否为import android.app.Activity; import android.os.Bundle; import android.view.Menu; import android.view.MenuItem; import android.view.View; import android.widget.Button; import com.esri.android.map.MapOptions; import com.esri.android.map.MapView; public class MainActivity extends Activity { MapView mMapView = null; Button b1; MapOptions options = new MapOptions(MapOptions.MapType.TOPO, 49.591241, 17.255503, 16); @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); mMapView = (MapView) findViewById(R.id.map); //mMapView.centerAndZoom(49.591241, 17.255503, 8); btnClick(); mMapView.setMapOptions(options); mMapView.setAllowRotationByPinch(true); mMapView.setRotationAngle(25); mMapView.enableWrapAround(true); } public void btnClick() { b1 = (Button) findViewById(R.id.button); b1.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View arg0) { //mMapView.centerAndZoom(49.591241, 17.255503, 10); mMapView.setMapOptions(options); } }); } @Override protected void onPause() { super.onPause(); // Call MapView.pause to suspend map rendering while the activity is paused, which can save battery usage. mMapView.pause(); } @Override protected void onResume() { super.onResume(); // Call MapView.unpause to resume map rendering when the activity returns to the foreground. mMapView.unpause(); } @Override public boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu; this adds items to the action bar if it is present. getMenuInflater().inflate(R.menu.menu_main, menu); return true; } @Override public boolean onOptionsItemSelected(MenuItem item) { // Handle action bar item clicks here. The action bar will // automatically handle clicks on the Home/Up button, so long // as you specify a parent activity in AndroidManifest.xml. int id = item.getItemId(); //noinspection SimplifiableIfStatement if (id == R.id.action_settings) { return true; } return super.onOptionsItemSelected(item); } }。这可以应用于任何对象。

如果没有返回任何空值，如何编写将值传递给excel表单元格的条件？
