java - 我如何使 if 语句中的 get 方法没有错误

Question

我想在继承自此类的其他类中使用 ids 值

if (title.equals("***")) {
                String ids = driver.findElement(By.name("Idsession")).getAttribute("value");
            }

我试图创建一个 get 方法，所以代码将是

 if (title.equals("***")) {
                String ids = driver.findElement(By.name("Idsession")).getAttribute("value");
public String getID() {
                        return ids;
                    }
                }

但是我遇到了错误

Exception in thread "AWT-EventQueue-0" java.lang.Error: Unresolved compilation problems: Syntax error on token(s), misplaced construct(s) Syntax error, insert ";" to complete Statement

Answer 1

您不能在方法内部创建方法。您必须声明 getIds() 在 block 像这样……

           public class name {

     private String ids = "";

    public static  void main(String arg[]){

       if (title.equals("***")) {
      // reinitialize id  when title is  equals '***'
    ids =driver.findElement(
By.name("Idsession")) .getAttribute("value");
  }

      String newThing = getID();
      //use it
      }

      // method declaration here

          public String getID() {
            return ids; 
           } 

   }
