方法一:
public static void writeToTxtByRandomAccessFile(File file, String str){
RandomAccessFile randomAccessFile = null
try {
randomAccessFile = new RandomAccessFile(file,"rw")
long len = randomAccessFile.length()
randomAccessFile.seek(len)
randomAccessFile.writeBytes(new String(str.getBytes(),"iso8859-1")+"\r\n")
} catch (FileNotFoundException e) {
e.printStackTrace()
}catch (IOException e) {
e.printStackTrace()
}finally{
try {
randomAccessFile.close()
} catch (IOException e) {
e.printStackTrace()
}
}
}
方法二:
public static void writeToTxtByFileWriter(File file, String content){
BufferedWriter bw = null
try {
FileWriter fw = new FileWriter(file, true)
bw = new BufferedWriter(fw)
bw.write(content)
} catch (IOException e) {
e.printStackTrace()
}finally{
try {
bw.close()
} catch (IOException e) {
e.printStackTrace()
}
}
}
方法三:
public static void writeToTxtByOutputStream(File file, String content){
BufferedOutputStream bufferedOutputStream = null
try {
bufferedOutputStream = new BufferedOutputStream(new FileOutputStream(file, true))
bufferedOutputStream.write(content.getBytes())
} catch (FileNotFoundException e) {
e.printStackTrace()
} catch(IOException e ){
e.printStackTrace()
}finally{
try {
bufferedOutputStream.close()
} catch (IOException e) {
e.printStackTrace()
}
}
}
