Selenium : Verify element - 1. ispresent 2. isvisible 3. isenable 4. textpresent

1. To check Element Present:
   

   if(driver.findElements(By.xpath("value")).size() != 0){
   System.out.println("Element is Present");
   }else{
   System.out.println("Element is Absent");
   }
   

   Or
   

   if(driver.findElement(By.xpath("value"))!= null){
   System.out.println("Element is Present");
   }else{
   System.out.println("Element is Absent");
   }
   

2. To check Visible:
   

   if( driver.findElement(By.cssSelector("a > font")).isDisplayed()){
   System.out.println("Element is Visible");
   }else{
   System.out.println("Element is InVisible");
   }
   

3. To check Enable:
   

   if( driver.findElement(By.cssSelector("a > font")).isEnabled()){
   System.out.println("Element is Enable");
   }else{
   System.out.println("Element is Disabled");
   }
   

4. To check text present
   

   if(driver.getPageSource().contains("Text to check")){
   System.out.println("Text is present");
   }else{
   System.out.println("Text is absent");
   }

5. WebElement rxBtn = driver.findElement(By.className("icon-rx"));
   WebElement otcBtn = driver.findElement(By.className("icon-otc"));
   WebElement herbBtn = driver.findElement(By.className("icon-herb"));

Assert.assertEquals(true, rxBtn.isDisplayed());
Assert.assertEquals(true, otcBtn.isDisplayed());
Assert.assertEquals(true, herbBtn.isDisplayed()); 

6. driver.findelement(By.id("id1")).isDisplayed()
  driver.findelement(By.id("id2")).sendkey("test"); 

Example :
 protected boolean isElementPresent(By by)
 {
   try {
    driver.findElement(by);
    return true;
       }
   catch (NoSuchElementException e)
  {
    return false;
  }
}
