One of the problem maybe that you need to use && in the following condition:

    if (args[0] != null || args[1] != null || args[2] != null) {// begin if

cHange it to:

    if (args[0] != null && args[1] != null && args[2] != null) {

Also the following check has the same logical problem:

        if ((name.equals("") || degree.equals("") || phone.equals(""))) {

should be :

        if ((name.equals("") && degree.equals("") && phone.equals(""))) {

I guess you are not passing all the arguments make your condition with logical and not or

 if (args[0] != null && args[1] != null && args[2] != null) {

And, you are on wrong track with configuring configure

student1.cfg.xml

I believe the above file is the mapping xml file for Student pojo.

Not the hibernate configuration file.

While dealing with hibernate read the properties from hibernate.cfg.xml file not from args.

You can easily do validation at once

package com.candidjava;

import java.sql.*;

import java.io.*;

import org.hibernate.SessionFactory;

import org.hibernate.Transaction;

import org.hibernate.HibernateException;

import org.hibernate.Session;

import org.hibernate.cfg.Configuration;

public class AddStudent {

private static SessionFactory sessionFactory1;

public static void main(String args[]) throws Exception {
     if ((name.equals("") && degree.equals("") && phone.equals(""))) {
            System.out.println("All informations are Required");
        } else {

        String name = args[0];
        String name1 = args[0];
        String degree = args[1];
        String phone = args[2];
        System.out.println("Name: " + name);
        System.out.println("Degree: " + degree);
        System.out.println("Phone: " + phone);   

            try {// begin try

                sessionFactory1 = new Configuration().configure(
                        "com\\xml\\student1.cfg.xml").buildSessionFactory();
            } catch (Exception e) {
                System.out.println("mathan");
                System.out.println(e.getMessage());
                System.err
                        .println("Initial SessionFactory creation failed."
                                + e);

            }

            Session s1 = sessionFactory1.openSession();
            Transaction tx1 = s1.beginTransaction();
            Student1 stu1 = new Student1();
            stu1.setName(name1);
            s1.save(stu1);
            tx1.commit();
            System.out.println("Added to mysql Database");
            if (s1 != null)
                s1.close();
        }
    }
}
