java中将java文件转换为html一个文件，先使用file类读取java文件，然后使用string进行分割、替换等 *** 作，输出html后缀名的文件，如下代码：
import java.io.BufferedReaderimport java.io.BufferedWriter
import java.io.File
import java.io.FileInputStream
import java.io.FileWriter
import java.io.IOException
import java.io.InputStreamReader
public class Change {
String textHtml = ""
String color = "#00688B"
//读取文件
public void ReadFile(String filePath) {
BufferedReader bu = null
InputStreamReader in = null
try {
File file = new File(filePath)
if (file.isFile() && file.exists()) {
in = new InputStreamReader(new FileInputStream(file))
bu = new BufferedReader(in)
String lineText = null
textHtml = "<html><body>"
while ((lineText = bu.readLine()) != null) {
lineText = changeToHtml(lineText)
lineText += "</br>"
textHtml += lineText
}
textHtml += "</html></body>"
} else {
System.out.println("文件不存在")
}
} catch (Exception e) {
e.printStackTrace()
} finally {
try {
bu.close()
} catch (IOException e) {
e.printStackTrace()
}
}
}
//输出文件
public void writerFile(String writepath) {
File file = new File(writepath)
BufferedWriter output = null
try {
output = new BufferedWriter(new FileWriter(file))
System.out.println(textHtml)
output.write(textHtml)
} catch (IOException e) {
e.printStackTrace()
} finally {
try {
output.close()
} catch (IOException e) {
e.printStackTrace()
}
}
}
//文件转换
public String changeToHtml(String text) {
text = text.replace("&", "&")
text = text.replace(" ", " ")
text = text.replace("<", "<")
text = text.replace(">", ">")
text = text.replace("\"", """)
text = text.replace(" ", " ")
text = text.replace("public", "<b><font color='"+color+"'>public</font></b>")
text = text.replace("class", "<b><font color='"+color+"'>class</font></b>")
text = text.replace("static", "<b><font color='"+color+"'>static</font></b>")
text = text.replace("void", "<b><font color='"+color+"'>void</font></b>")
String t = text.replace("//", "<font color=green>//")
if (!text.equals(t)) {
System.out.println("t:"+t)
text = t + "</font>"
}
return text
}
public static void main(String[] args) {
System.out.println("第一个参数为读取文件路径，第二个参数为生成文件路径")

使用Java中的File类，url为文件的绝对地址，str为输入的字符串内容。代码如下图所示：String str="i love china!" File txt=new File("url") if(!txt.exists()){ txt.createNewFile() } byte bytes[]=new byte[512] bytes=str.getBytes() //新加的 int b=str.length() //改 FileOutputStream fos=new FileOutputStream(txt) fos.write(bytes,0,b) fos.close()欢迎分享，转载请注明来源：内存溢出
