    Hi saurabh,

    Standard exceptions that salesforce throws :

    DmlException

    ListException

    NullPointerException

    QueryException

    SObjectException
    You can use common exception methods to get more information about an exception, such as the exception error message or the stack trace. The previous example calls the getMessage method, which returns the error message associated with the exception. There are other exception methods that are also available. Here are descriptions of some useful methods:
    getCause: Returns the cause of the exception as an exception object.
    getLineNumber: Returns the line number from where the exception was thrown.
    getMessage: Returns the error message that displays for the user.
    getStackTraceString: Returns the stack trace as a string.
    getTypeName: Returns the type of exception, such as DmlException, ListException, MathException, and so on.

    Thanks
