FileInputStream [英] FileInputStream
问题描述
大家好，
谁能告诉我标线的作用?我的意思是，下面的代码分别具有什么功能.
公共静态void main(String args [])
{
VRJDBCPropXmlHandler处理程序=新的VRJDBCPropXmlHandler();
试试
{
FileInputStream fin =新的FileInputStream(args [1]); --------------> ???
handler.execute(fin);
}
catch(FileNotFoundException fnfe)
{
fnfe.printStackTrace();
}
catch(Exception e)
{
e.printStackTrace();
}
}
公共无效execute(InputStream is)引发异常{
SAXParser解析器= spf_.newSAXParser();
尝试
{
parser.parse(是这个); ----------------------> ???
}
捕获(异常)
{.....
}
Hi all,
can anyone please tell me what does the marked lines do ? I mean, what is their functionality respective of the code below.
public static void main(String args[])
{
VRJDBCPropXmlHandler handler = new VRJDBCPropXmlHandler();
try
{
FileInputStream fin = new FileInputStream(args[1]); --------------> ???
handler.execute(fin);
}
catch(FileNotFoundException fnfe)
{
fnfe.printStackTrace();
}
catch(Exception e)
{
e.printStackTrace();
}
}
public void execute(InputStream is) throws Exception {
SAXParser parser = spf_.newSAXParser();
try
{
parser.parse(is, this); ----------------------> ???
}
catch (Exception ex)
{.....
}
推荐答案
此行使用args [1]作为路径打开一个文件以流形式读取.变量"args"包含命令行参数.
This line opens a file for reading as a stream,using args[1] as the path. The variable "args" contain the command line arguments.
FileInputStream fin = new FileInputStream(args[1]);
此行使用包含的类作为DefaultHandler将文件解析为XML XML ^ ]
This line parses the file as XML using the containing class as a DefaultHandler DefaultHandler[^]
parser.parse(is, this);

@rick:rick. FileInputStream(args [1])为什么会有args [1]参数?如何在这里使用?您能详细解释一下吗?
@rick: hi rick. FileInputStream(args[1]) why is there args[1] parameter ? How can it be used over here? can you please explain in detail ?
