先以简单的文件读写实现为基础,FileHelper类中的readFile方法用于读取文件内容,writeFile方法用于向文件中写入内容。
import java.io.BufferedReader; import java.io.BufferedWriter; import java.io.FileReader; import java.io.FileWriter; public class FileHelper { public static String readFile(String filename) throws Exception { BufferedReader reader = new BufferedReader(new FileReader(filename)); String ans = "", line = null; while((line = reader.readLine()) != null){ ans += line + "\r\n"; } reader.close(); return ans; } public static void writeFile(String content, String filename) throws Exception { BufferedWriter writer = new BufferedWriter(new FileWriter(filename)); writer.write(content); writer.flush(); writer.close(); } public static void main(String[] args) throws Exception { String ans = readFile("D:\\input.txt"); writeFile(ans, "D:\\output.txt"); } }
然后在FileHelper类的基础上写一个WebpageMaker类,其createPage方法用于将特定文件中的内容生成在特定的网页中。
其中如果要插入代码可以将代码加入中。
import java.util.StringTokenizer; public class WebpageMaker { public static String initBegin() { String s = "\r\n"; return s; } public static String initEnd() { String s = "\r\n\r\n"; return s; } public static void createPage(String inputfilename, String outputfilename) throws Exception { String cOntent= FileHelper.readFile(inputfilename); StringTokenizer st = new StringTokenizer(content, "\r\n"); String ans = ""; ans += initBegin(); boolean isCoding = false; while(st.hasMoreElements()) { String s = st.nextToken(); int len = s.length(); for(int i=0;i")) { isCoding = true; ans += " "; i += 5; continue; } if(i+7 <= len && s.substring(i,i+7).equals("")) { isCoding = false; ans += ""; i += 6; continue; } char c = s.charAt(i); if(c == '\"') ans += """; else if(c == '&') ans += "&"; else if(c == '<') ans += "<"; else if(c == '>') ans += ">"; else if(c == ' ') ans += " "; else if(c == '\t') ans += " "; else ans += c; } if(false == isCoding) ans += "
\r\n"; else ans += "\r\n"; } ans += initEnd(); FileHelper.writeFile(ans, outputfilename); } public static void main(String[] args) throws Exception { createPage("D://test.txt", "D://test.html"); } }
样例:
输入文件:test.txt
hello world! 大家好:) #include int main() { printf("hello world!\n"); return 0; }
输出文件:test.html
hello world!
大家好:)
#includeint main() { printf("hello world!\n"); return 0; }
效果如下:
hello world! 大家好:) #includeint main() { printf("hello world!\n"); return 0; }
