open, write and close a text file
developer task
study the project notes on this page to understand how to write values to a simple text file
fork the project and test the code with some text values
create a new project to implement a solution to the exercise at the foot of this page
you should have read the general notes about writing a file
program requirement: write a text file (example)
text file: output
the results file should contain a list with a value on each line
FrenchArt and DesignBiologyDanceComputing Sciencestored in text format with newline character after each line except for the last line
French\nArt and Design\nBiology\nDance\nComputing Sciencejava code constructs to write to a file
open file
String outputFile = "subjects.txt";PrintWriter fileWriter = new PrintWriter(outputFile);• choose a name for the file and open it for writing
write (a line) to file
fileWriter.print(subject[i]);
if (i<subject.length-1) { fileWriter.print("\n");} // end if• use fileWriter with print to output a line of text
• a newline should be added after each line of text, apart from the last line
this code will be nested within a loop to repeat for each value in the array
close file
fileWriter.close();program code
exercise: binary headings
write a list to a text file for the binary place headings for 8 bite two’s complement starting with -128
