JAVA读文件，并转为String类型源码示例

public String getXmlString() {

String xmlString;

byte[] strBuffer = null;

int flen = 0;

File xmlfile = new File("/data/local/getHomePage.xml");

try {

InputStream in = new FileInputStream(xmlfile);

flen = (int)xmlfile.length();

strBuffer = new byte[flen];

in.read(strBuffer, 0, flen);

} catch (FileNotFoundException e) {

// TODO Auto-generated catch block

e.printStackTrace();

} catch (IOException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

xmlString = new String(strBuffer); //构建String时，可用byte[]类型，

return xmlString;

}
