I want my code to read the input file, line by line
When I use the while loop, it only read the second line this the
code:
import java.io.File;
import java.io.IOException;
import java.io.UnsupportedEncodingException;
import java.util.*;
public class Tester2 {
/**
* main method
* @param args the args from JVM
*/
public static void main(String args[]) throws
IOException{
Scanner sc= new Scanner(System.in);
//System.in is a standard input stream

//For holding string
String test = "";
//Reading data from file rather than
from input - Assuming input file is data.txt
try {
//Scanner object to read
data from file
Scanner fileReader = new
Scanner(new File("filetoencode.txt")); //System.in is a standard
input stream

//Reading data from
file
while
(fileReader.nextLine() != null){
test =
fileReader.nextLine();
}

//Closing file
reader
fileReader.close();
}
catch(Exception ex) {

System.out.println(ex);
}
// System.out.print("You have entered: "+
test);
//String test = "";// THE TESTING
STRING!!!
System.out.println("Testing String: " +
test);
int size = 0;
try {
size =
test.getBytes("utf8").length * Byte.SIZE;//SIZE OF THE STRING IN
BIT
} catch (UnsupportedEncodingException e)
{
System.out.println("Not
proper encoding...");
}
HuffmanFrequencyTable test2 = new
HuffmanFrequencyTable(test);//BUILD HUFFMAN TABLE
HuffmanTree test3 = new
HuffmanTree(test2.getTable());// BUILD HUFFMAN TREE
Encoder tst4 = new Encoder(test3,
test2.getTable());// ENCODING
String test5 =
tst4.result(test);//ENCODING RESULT
tst4.print();//PRINT FREQUENCY TABLE
WITH CODE FOR EACH CHARACTER
int sizeb = test5.length();//SIZE IN BIT
OF ENCODED STRING
System.out.println("Encoded bit
stream:");
System.out.println(test5);
System.out.println("Total number of bits
without Huffman coding: " + size);
System.out.println("Total number of bits
with Huffman coding: " + sizeb);
System.out.println("Decoded String: " +
Decoder.decode(test5, test3));

}
}
This code only read the first line
