Error when using sendKeys() with Selenium WebDriver Java.lang.CharSequence cannot be resolved

Question

I have imported the following and still get an error when using sendKeys();

import org.openqa.selenium.*;
import org.openqa.selenium.firefox.*;
import org.testng.Assert;
import org.openqa.selenium.WebDriver;

Note: I am using Selenium WebDriver with Eclipse.

The sample code is as below.

import org.openqa.selenium.*;
import org.openqa.selenium.firefox.*;
import org.testng.Assert;
import org.openqa.selenium.WebDriver;

public class Practice {

    public static void main(String[] args)
      {

        WebDriver driver = new FirefoxDriver();
        String baseUrl = "http://www.facebook.com";

        String tagName="";
        driver.get(baseUrl);
        tagName = driver.findElement(By.id("email")).getTagName();
        System.out.println("TagName: "+tagName);    
        WebElement myElement = driver.findElement(By.id("username"));
        myElement.sendKeys("text");
      }
}

I received an error stating

The type java.lang.CharSequence cannot be resolved. It is indirectly referenced from required .class files

Pointing at the line myElement.sendKeys("text");

Can one of you let me know what is incorrect here.

Solution 1

You could try this, similar issue has been answered here #sendKeys Issue

myElement .sendKeys(new String[] { "text" }); //You could create a string array 

or simply

myElement .sendKeys(new String { "text" });

Solution 2

It needs to upgrade the Compiler Compliance. For Eclipse: Follow the steps below:

1. Right click on your java project and select Build Path -> Click on Configure Build Path...
2. In project properties window: Click/select Java Compiler at the left panel
3. At the right panel: change the Compiler compliance level from 1.4 to 1.7 or higher
4. Lastly Click on Apply and OK

Solution 3

I faced the same problem during using eclipse Kepler.

Problem domain:
My java compiler compliance level was 1.4

Solution:
so using build path >> configure build path>> java compiler>> changed the compiler compliance level to 1.7 or higher

This could solve the problem.

Thanks for the info. the line "myElement .sendKeys(new String { "text" });" worked with JRE7. However, when I switch the JRE to 8 it throws The method sendKeys(CharSequence[]) from the type WebElement refers to the missing type CharSequence. Have you experienced this before?

I'm getting the same issue with .contains(CharSequence...) when switching from 1.7 to 1.8.

What is the difference between String and String array in this case? It needs to pass a String as parameter in sendKeys method. It's better to pass simple and single String rather than array of Strings.
