Moving settings and program configurations, on the other hand, was not possible, except for the experts, and you had to reconfigure each of the applications on the new computer. E-mail could be moved but was a difficult a process. The main problem using these methods was that you could only move files such as documents, pictures, movies, saved games, etc.
#THE CONNECTION PROGRAM COPY INSTALL#
In the past when you wanted to transfer data you had to copy the data via a network, store it onto a DVD/CD/Floppy and then copy it back onto the new PC, or physically take the hard drive out of the old machine and install it into the new machine. When purchasing a new computer one of the most frustrating experiences is moving existing data to the new computer from the older one.

Hopefully you enjoyed reading this tutorial. function to copy the contents of one file to anotherīufferedReader br = new BufferedReader(new FileReader(a)) īufferedWriter bw = new BufferedWriter(new FileWriter(b)) Īnd I got the joining call the next day. I realized that I had to do the same thing thrice that is copying the content of one file to another so I declared another function copy(String, String) to do it. If you ignore this line nothing will get printed. There is also an interesting addition that is the flush() method which actually writes the lines into the files from the buffers. Also he asked questions about the connection I made with the BufferedReader and BufferedWriter with FileReader and FileWriter. The answer is BufferedReader is a lot faster than Scanner because it buffers the character so you don’t have to access the file each time you want to read a char from it.
I used BufferedReader and BufferedWriter and not any other classes which actually impressed the interviewer and he even asked me why I didn’t use Scanner. copy the contents of temp.txt to file2.txtīr = new BufferedReader(new FileReader("temp.txt")) īw = new BufferedWriter(new FileWriter("File2.txt")) copy the contents of file2.txt to a file1.txtīr = new BufferedReader(new FileReader("File2.txt")) īw = new BufferedWriter(new FileWriter("File1.txt")) copy the contents of file1.txt to temp.txtīufferedReader br = new BufferedReader(new FileReader("File1.txt")) īufferedWriter bw = new BufferedWriter(new FileWriter("temp.txt")) File 1 and File2 are the names of the files to be swapped. Now replace it with File1.txt and File2.txt for the swapping with files. Copy the content of var1 to a temporary variable temp. These are the steps to swap two variables var1 and var2.ġ. Just use the normal method of swapping two variables. Program to swap the contents of two files in Java? And one more thing that was the first time I used File Handling in Java. And luckily I managed to impress him with my program. Though it’s a very simple program what the interviewer was trying to see was if I knew the use of File Handling properly. I managed to do the program and finally got the job. I was given a computer with an IDE and was even allowed to use the internet. This program was asked to me during an interview.
