<!doctype html>   <html>  <head>  <meta charset="iso-8859-1">  <title>my life</title><style>   h1 {text-align:center;}   </style>   </head>    <body></body></html>

here bio.txt input file

[h1] i? name billy. senior cs major. [h1] interests? develop skillset in software , web development , possibly start career in it. [h1] why taking class? taking class because i'd enhance web development skills. [h1] 5 year plan? 5 year plan graduate cs major , earn great job enjoy.

just small correction in order of method execution. need read , initialize heading , paragraphs first, followed writing in html file.

public static void main(string[] args) {     initialize(output_file);     readparagraphs(input_file);     writebio(title);     system.out.println("completed"); }
