使用硒罐文件时，我在Eclipse中遇到此错误：

Question

Following is my simple Java code for selenium :

package myPackage;

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;

public class MyClass {

   public static void main(String[] args) {

     System.out.println("My First Selenoium Class");

     WebDriver driver = new FirefoxDriver();
     String baseURL = "http://newtours.demoaut.com";
     String expectedTitle = "Welcome: Mercury Tours";
     String actualTitle = "";

     driver.get(baseURL);
     actualTitle = driver.getTitle();


     if(actualTitle.contentEquals(expectedTitle)){
        System.out.println("Titles are same");
     }
     else {
        System.out.println("Different Titles");
     }

     driver.close();
     System.exit(0);
   }

}

There are 2 errors occuring at the if condition:

Error1 : The method contentEquals(StringBuffer) in the type String is not applicable for the arguments (String).
Error2 : The type java.lang.CharSequence cannot be resolved. It is indirectly referenced from required .class files

Please help me resolving this.

Answer 1

contentEquals需要一个StringBuffer参数：

StringBuffer expectedTitle = "Welcome: Mercury Tours";
