Software Technology Tips

The following tip demonstrates how to read and write data to a file in Java. The code snippet below reads text data from a predefined text file and creates an HTML equivalent.. You can also use it to generate PHP, Javascript and other text-based files..

import java.io.BufferedReader;
import java.io.File;
import java.io.FileOutputStream;
import java.io.FileReader;
import java.io.OutputStream;
import java.io.PrintStream;

public class TexttoHTML

{

public static void main(String[] args) {

try {

            BufferedReader txtfile = new BufferedReader(new FileReader("c:\\test.txt"));
            OutputStream htmlfile= new FileOutputStream(new File("c:\\test.html"));
            PrintStream printhtml = new PrintStream(htmlfile);

            String[] txtbyLine = new String[500];
            String temp = "";
            String txtfiledata = "";

            String htmlheader="<html><head>";
            htmlheader+="<title>Equivalent HTML</title>";
            htmlheader+="</head><body>";
            String htmlfooter="</body></html>";
            int linenum = 0 ;

            while ((txtfiledata = txtfile.readLine())!= null)
               {
                    txtbyLine[linenum] = txtfiledata;
                    linenum++;
                }
            for(int i=0;i<linenum;i++)
                {
                    if(i == 0)
                    {
                        temp = htmlheader + txtbyLine[0];
                        txtbyLine[0] = temp;
                    }
                    if(linenum == i+1)
                    {
                        temp = txtbyLine[i] + htmlfooter;
                        txtbyLine[i] = temp;
                    }
                    printhtml.println(txtbyLine[i]);
                }

        printhtml.close();
        htmlfile.close();
        txtfile.close();

}

catch (Exception e) {}
}
}
