eclipse - 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.

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
