Here is the file for writing text files. We tried to make it as generic as possible so it can be reused in a variety of contexts. One weakness of the class is that it is up to the user to call the closeFile method. A text file cannot be read or used if it is not closed
WriteFile.java
package com.spconger.www;
import java.io.*;
public class WriteFile {
private String path;
private PrintWriter writer;
public WriteFile(String path) throws IOException{
this.path=path;
createFile();
}
private void createFile() throws IOException{
FileWriter outFile = new FileWriter(path, true);
writer = new PrintWriter(outFile);
}
public void addText(String content){
writer.println(content);
}
public void closeFile(){
writer.close();
}
}
Here is the ReadFile.Java
package com.spconger.www;
import java.io.*;
public class ReadFile {
private String path;
public ReadFile(String path){
this.path=path;
}
public String getText() throws FileNotFoundException ,IOException{
String content="";
FileInputStream fstream = new FileInputStream(path);
DataInputStream in = new DataInputStream(fstream);
BufferedReader br = new BufferedReader(new InputStreamReader(in));
String strLine;
while ((strLine=br.readLine()) != null){
content += (strLine + "\n");
}
return content;
}
}
Here is the Program.java where we test our classes
package com.spconger.www;
import java.io.IOException;
public class Program {
/**
* @param args
*
*/
public static void main(String[] args) {
try {
WriteFile write = new WriteFile("email.txt");
write.addText("Steve" + ", steven.conger@seattlecolleges.edu");
write.addText("George" + ", george@gmail.com");
write.closeFile();
ReadFile read = new ReadFile("email.txt");
System.out.println(read.getText());
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
