Hi friend,
We check the code having some changes to correct the code :
Changes in this lines code :
Writer output = null;
to
BufferedWriter output = null;
Correct Code :
import java.io.*;
import java.util.*;
import java.lang.Integer;
import java.io.PrintWriter;
import java.io.OutputStreamWriter;
import java.io.FileWriter;
import java.io.Writer;
import java.io.BufferedWriter;
import java.io.IOException;
public class DataToBinary{
public static void main(String[] args) throws IOException{
System.out.println("Data types conversion example!");
int num = 100;
BufferedWriter output = null;
File file = new File("numbers.txt");
output = new BufferedWriter(new FileWriter(file));
for(int i =0 ; i<num; i++){
System.out.println("Integer: " + i);
String byt = Integer.toBinaryString(i);
String s = "0";
while(byt.length()<8){
byt= s+ byt;}
System.out.println(" Byte: " +byt);
output.write(byt);
output.newLine( ) ;
}
output.close();
System.out.println("Your file has been written");
}
}
