Otherwise, the dialogue box indicates that the information does not exist in the database. The clear button will clear all the information on the GUI.arrow_forwardin java but don't write as a GUI (Graphical User Interface) Write a program that reads a file named input.txt and writes a file that contains the same contents, but is named output.txt. The input file will contain more than one line when I test this and so should your output file. Do not use a path name when opening these files. This means the files should be located in the top level folder of the project. This would be the folder that contains the src folder, probably named FileCopy depending on what name you gave the project. Do not use a copy method that is supplied by Java. Your program must read the file line by line and write the file itself. Class should be named FileCopy do not write to input.txt!arrow_forwardPython Required information id fname lname company address city ST zip 103 Art Venere 8 W Cerritos Ave #54 Bridgeport NJ 8014 104 Lenna Paprocki Feltz Printing 639 Main St Anchorage AK 99501arrow_forward
