Java: Error when reading a file
All,
I'm trying to read and output the contents of a file called credentials.txt. The code is below and attached is the error I'm getting.
package testingrandommethods;
import java.util.Scanner;
import java.io.*;
public class TestingRandomMethods {
public static void main(String[] args) throws IOException { //I had an error until I added "throws IOException" when trying to open the file.
FileInputStream fileByteStream = null;
Scanner credFile = null;
String credData = "";
//Attempt to open file
fileByteStream = new FileInputStream("credentia
credFile = new Scanner(fileByteStream); //credFile now contains what's in credentials.txt.
System.out.println("Readin
credData = credFile.next(); //credData now contains what's in credentials.txt as well. It allows me to read through the file.
while (credData.charAt(0)){
System.out.println(credDat
credData = credFile.next();
}
System.out.println(credDat
//Close the file
System.out.println("Closin
fileByteStream.close();
return;
}
}

won't compile because the method of String that you're calling returns char, not boolean. Unlike other languages, conversion to boolean is not possiblewhile(credData.charAt(0))
