Need output of characters instead of numbers
Here is a simple example of reading a text file as integers and
displaying each with blank spaces in between.
import java.io.*;
public class Nvj3 {
public static void main(String[] args){
try {
FileInputStream file = new FileInputStream("NVRAM.TXT");
boolean eof = false;
int count = 0;
while (!eof) {
int input = file.read();
System.out.print(input + " ");
if (input == -1)
eof = true;
else
count++;
}
System.out.println("Bytes read : " + count);
} catch (IOException e){
System.out.println("Could not read file");
}
}
}
OUTPUT is positive integers less than 128 (ASCII):
78 86 82 65 77 44 32 86 101 114 115 105 111 110 32 49 46 50 48 13 10
78 111 110 45 86 111 108 97 116 105 108 101 32 82 65 77 32 83 121 115
I looked at the input file with a hex editor and the ASCII chars are all
stored as bytes - not integers.
I HAVE TWO QUESTIONS: the statement: int input = file.read();
reads the file as a bunch of integer type values but the output is in
character type. It seems like the correct input statement would be:
char input = file.read();
I tried that and it is an error. QUESTION 1): Can someone explain why
the file is read as char type but the statement says int type?
QUESTION 2) What do I need to do to get ASCII characters as output
instead of numbers?
