Can somebody help on this, Why Sendkeys() method is not taking String values as arguments?

Try to click into the WebElement before you sending keys to it:
在向 WebElement 发送密钥之前尝试单击它：
public static void login(WebDriver driver, String userName, String password) {
driver.get("loginPage.html");
Thread.sleep(3000);
driver.findElement(By.id("username")).click();
driver.findElement(By.id("username")).clear();
driver.findElement(By.id("username")).sendKeys(userName);
Thread.sleep(TestConfiguration.time);
driver.findElement(By.id("password")).click();
driver.findElement(By.id("password")).clear();
driver.findElement(By.id("password")).sendKeys(password);
Thread.sleep(3000);
driver.findElement(By.name("login")).click();
Thread.sleep(3000);
}
You should use clear() method to clear the input field before using sendKeys().
在使用 sendKeys() 之前，您应该使用 clear() 方法清除输入字段。

You can try by replacing your following lines of code:
您可以尝试替换以下代码行：
driver.findElement(By.id("password")).sendKeys("nag123");
driver.findElement(By.id("repassword")).sendKeys);
driver.findElement(By.id("altemail")).sendKeys();
driver.findElement(By.id("mobileno")).sendKeys("7894561230");
driver.findElement(By.id("imageField")).click();
to
到
driver.findElement(By.id("password")).sendKeys("nag123");
driver.findElement(By.id("repassword")).sendKeys("");
driver.findElement(By.id("altemail")).sendKeys("");
driver.findElement(By.id("mobileno")).sendKeys("7894561230");
driver.findElement(By.id("imageField")).click();

Depending on the version of java you need to either convert the primitive (i.e. Char) to String (look here: http://tech.deepumohan.com/2013/03/java-how-to-convert-primitive-char-to.html)
根据 Java 的版本，您需要将原始（即 Char）转换为字符串（请看这里：http: //tech.deepumohan.com/2013/03/java-how-to-convert-primitive-char-to .html)
Or switch to a java version that would do it for you (see here: http://java-performance.info/changes-to-string-java-1-7-0_06/)
或者切换到可以为您完成的 Java 版本（请参见此处：http: //java-performance.info/changes-to-string-java-1-7-0_06/）
