Hi friend,
Code to solve the problem :
import java.io.*;
class FileRead
{
public static void main(String args[])
{
try{
// Open the file that is the first
// command line parameter
FileInputStream fstream = new FileInputStream("textfile.txt");
// Get the object of DataInputStream
DataInputStream in = new DataInputStream(fstream);
BufferedReader br = new BufferedReader(new InputStreamReader(in));
String strLine;
//Read File Line By Line
while ((strLine = br.readLine()) != null) {
// Print the content on the console
int strlen = strLine.length();
String strAr[] = new String[strlen];
//System.out.println("Intialize Array : " + strAr.length);
for(int i=0;i<strAr.length;i++)
{
System.out.print(strLine.charAt(i));
}
System.out.println();
}
//Close the input stream
in.close();
}catch (Exception e){//Catch exception if any
System.err.println("Error: " + e.getMessage());
}
}
}
Thanks
