how to know text is present or not in selenium-java

 How to know text is present or not in selenium , we have to validate it 

I visited man website , for validate , but few are asking with assert/verify , include some library file and etc .

but when i tired from my end , i got this working code for validation without include any jar file

for validate we will use following code :

   // Validate text is present or not 

        if(driver.getPageSource().contains("text")){

        System.out.println("Text is present");

        }else{

        System.out.println("Text is absent");

        }

you dont need to add path and all , as a step you have to copy and paste this code.

 if(driver.getPageSource().contains("text")) in this instead of "text", enter text which you want to verify.

so , if your text is present it will print " Text is Present" else it will print "Text is absent"
