Answer 1

If you are trying to get the the id of the link that you have mentioned. Please try modified code below.

WebElement Clientlist = driver.findElement(By.xpath("//a[@id='MnClient']"));
Clientlist.click();

WebElement Clientclick = driver.findElement(By.xpath("//*[@id='ctl00_MainContent_ctl00_RadGridList_ctl00__0']/td[2]/a"));
Clientclick.click();
Thread.sleep(2000);
String attribute = driver.findElement(By.xpath("//a[@class='case-hdr']"))
//WebElement attribute= driver.findElement(Clienthover);

attribute.getAttribute("id");
System.out.println(attribute);

If you want href then you can try below code

String attribute = driver.findElement(By.xpath("//a[@class='case-hdr']"))
//WebElement attribute= driver.findElement(Clienthover);

attribute.getAttribute("href");
System.out.println(attribute);
