Java Program To Create New File

The below Java program creates new blank file named MyFirstFile.txt by passing  file name as argument to the constructor of File object. We must have to place file creation code in try block because it may throw IOException. We can check whether new file is created or not by using createNewFile() method of File object and place it in if...else condition.

import java.io.*;
class CreateFile
{
  
 public static void main(String[] args) 
 {
  
  try
  {
   /*Creates File MyFirstFile.txt in current Directory*/
   File f1=new File("MyFirstFile.txt"); 
   
   if(f1.createNewFile())
    System.out.println("File Created Successfuly!");
   else
    System.out.println("Fail to Create File!");
  
  }

  catch(IOException e)
  {

  }

 }
}

Job Placement is Now Done By GTU

2^nd November, GTU (Gtjarat Technological University) announced that the job placement is done by GTU for all collages affiliated to GTU. Gujarat Technological University affiliated colleges of Engineering, MCA, MBA, ME, and Pharmacy colleges are located in various region of Gujarat. Students are very confused for college selection when they are going to take admission in one of the above course. Student pay donation to take admission in top ten colleges of Gujarat because all major companies going to arrange the Job Placement fair in these colleges. The students studying in colleges other than top ten colleges has ability to work in top companies stil they didn't get opportunity to participate in the job placement. Due to above reason powerful students can not get good job.

After doing research on this reality the GTU  decided to take job placement in its hands. As per GTU announcement no companies can arrange their job placement in selected college. Now the GTU going to centralized the job placement process and planning to give similar opportunities to every students.

On 3^rd December, GTU going to organize meeting of all placement officers who are involved in job placement. I really appreciate the decision of GTU, now every student of GTU affiliated colleges get similar opportunity for good job whether they studying in top ten colleges or not.
