Question

我正在用java编写一个程序，每次运行时都会创建一个HTML模板。它读取输入的bio txt文件，该文件由四个标题和每个段落一行组成。它采用txt并将标题和段落存储为并行数组。然后我将数组写入HTML文件。问题是，当我运行它时，没有输入文件，它也说读者永远不会关闭。这是我的程序和输出。感谢您的任何建议。

    private static void writeHTML(String anHTMLString) {

    private static void writeBio(String title) {

        writeParagraphs();
        writeHTMLClosing();
    }


    private static void writeHTMLOpening(String title) {

        writeHTML(HTMLTags.TITLE_START + title + HTMLTags.TITLE_END);

    public static void main(String[] args) {
        initialize(OUTPUT_FILE);
        writeBio(TITLE);
        readParagraphs(INPUT_FILE);
        System.out.println("completed");

    }
}

这是我的bio.txt输入文件

<!DOCTYPE html> 
<html>
<head>
<meta charset="ISO-8859-1">
<title>My LIfe</title><style> 
h1 {text-align:center;} 
</style> 
</head>  
<body></body></html>

按方法执行顺序进行小幅修正。您需要首先阅读并初始化标题和段落，然后将其写入html文件。

public static void main(String[] args) {
    initialize(OUTPUT_FILE);
    readParagraphs(INPUT_FILE);
    writeBio(TITLE);
    System.out.println("completed");
}

我无法运行每次运行时创建html模板的程序
