1.方法1
public static void main(String[] args) {
try {
FileWriter fileWriter = new FileWriter("c:\\Result.txt");
String ss = "cName\t\cCode\t\tcreateDate\n";
ss += "dbc券\t\t111188\t\t2017-05-14\n";
ss += "zc券\t\t111199\t\t2017-05-14\n";
fileWriter.write(ss);
fileWriter.flush();
fileWriter.close();
} catch (Exception e) {
e.printStackTrace();
}
System.out.println(">>>>>>>>>>>>>>>>>>write end");
try {

BufferedReader br = new BufferedReader(fileReader);
String s;
while ((s = br.readLine()) != null) {
System.out.println(s);
}
fileReader.close();
} catch (Exception e) {

} System.out.println(">>>>>>>>>>>>>>>>>>read end");}
2.方法2
public static void main(String[] args) {
File f = new File("c:\\temp.txt");
OutputStream out = null;
try{
out = new FileOutputStream(f);
}catch (FileNotFoundException e){
e.printStackTrace();
}
String ss = "cName\t\tcCode\t\tcreateDate\n";
ss += "dbc券\t\t111188\t\t2017-05-14\n";
ss += "zc券\t\t111199\t\t2017-05-14\n";
// 将字符串转成字节数组
byte b[] = ss.getBytes();
try
{
// 将byte数组写入到文件之中
out.write(b);
out.close();
}catch (IOException e1){
e1.printStackTrace();
}
System.out.println("write end>>>>>>>>>>>");
// 以下为读文件操作
InputStream in = null;
try{
in = new FileInputStream(f);
}catch (FileNotFoundException e3){
e3.printStackTrace();
}
// 开辟一个空间用于接收文件读进来的数据
byte b1[] = new byte[1024];
int i = 0;
try{
// 将b1的引用传递到read()方法之中，同时此方法返回读入数据的个数
i = in.read(b1);
in.close();
}catch (IOException e4){
e4.printStackTrace();
}
// 将byte数组转换为字符串输出
System.out.println(new String(b1, 0, i));
System.out.println("read end>>>>>>>>>>>");
