调用封装的方法：私有方法

public class encapsulation {

public void main () {

      WebDriver driver = new FirefoxDriver();
      driver.get(baseurl);       

      driver.findElement(By.linkText(searchscope[i])).click();

 

      waitForTimeOut (3000);   

  

      driver.manage().deleteAllCookies();

      driver.quit();    
}

 

private void waitForTimeOut(int m) {
 try {
  Thread.sleep(m);
 } catch (InterruptedException e) {
  e.printStackTrace();
 } 
}

 

 

}
