1、JAVA读取文件，避免中文乱码。
/**
* 读取文件内容
*
* @param filePathAndName String 读取文件路径
* @return String 文件中的内容
*/
public static String readFile(String filePathAndName) {
String fileContent = "";
try {
File f = new File(filePathAndName);
if(f.isFile()&&f.exists()){
InputStreamReader read = new InputStreamReader(new FileInputStream(f),"UTF-8");
BufferedReader reader=new BufferedReader(read);
String line;
while ((line = reader.readLine()) != null) {
fileContent += line;
}
read.close();
}
} catch (Exception e) {
System.out.println("读取文件内容操作出错");
e.printStackTrace();
}
return fileContent;
} [NextPage] 2、JAVA写入文件，避免中文乱码。
/**
* 写文件
*
* @param filePathAndName String 写文件路径
* @param fileContent String 需要写入的内容
*/
public static void writeFile(String filePathAndName, String fileContent) {
try {
File f = new File(filePathAndName);
if (!f.exists()) {
f.createNewFile();
}
OutputStreamWriter write = new OutputStreamWriter(new FileOutputStream(f),"UTF-8");
BufferedWriter writer=new BufferedWriter(write);
//PrintWriter writer = new PrintWriter(new BufferedWriter(new FileWriter(filePathAndName)));
//PrintWriter writer = new PrintWriter(new FileWriter(filePathAndName));
writer.write(fileContent);
writer.close();
} catch (Exception e) {
System.out.println("写文件内容操作出错");
e.printStackTrace();
}
}
