joshua matthews :
I am a very novice programmer trying to read a text file in Java Eclipse.
Here is my code:
package readFromfile;
import java.io.File;
import java.io.FileNotFoundException;
import java.util.Scanner;
public class justDo {
public static void main(String[] args) throws FileNotFoundException {
System.out.println(System.getProperty("user.dir"));
File file = new File(System.getProperty("user.dir") +
"/src/report.txt");
Scanner hemp = new Scanner(file);
System.out.println(hemp);
}
}
Instead of reading a text file and displaying the file's contents in the console I get this:
C:\Users\Vanessa\eclipse-workspace\readFromfile
java.util.Scanner[delimiters=\p{javaWhitespace}+][position=0][match
valid=false][need input=false][source closed=false][skipped=false][group
separator=\,][decimal separator=\.][positive prefix=][negative prefix=\Q-
\E][positive suffix=][negative suffix=][NaN string=\QNaN\E][infinity
string=\Q?\E]
Can someone please explain why I am getting this and explain how to properly read a text file in Java Eclipse? Please help. Thank you all so much in advance.
Beto Rodriguez :
You are printing the Scanner object, not the File read. To do that you have to run over the Scanner content, here is an example:
import java.io.*;
import java.util.*;
public class Main
{
public static void main(String[] args) throws FileNotFoundException {
System.out.println(System.getProperty("user.dir"));
File file = new File(System.getProperty("user.dir") + "/src/report.txt");
Scanner hemp = new Scanner(file);
while (hemp.hasNextLine())
System.out.println(hemp.nextLine());
}
}
If you want to read more about the Scanner functions you can get it on the API docs:
