javaDataInputStream和DataOutputStream详解
操作基本数据类型的流
DataInputStream
DataOutputStream
importjava.io.DataInputStream;
importjava.io.DataOutputStream;
importjava.io.FileInputStream;
importjava.io.FileOutputStream;
importjava.io.IOException;
publicclassIntegerDemo{
publicstaticvoidmain(String[]args)throwsIOException{
myWrite();
myReader();
}
privatestaticvoidmyWrite()throwsIOException{
//TODOAuto-generatedmethodstub
//创建数据输出流对象
FileOutputStreamfos=newFileOutputStream("E:\\zikao\\file\\cs.txt");
DataOutputStreamdos=newDataOutputStream(fos);
//写数据
dos.writeByte(10);

dos.writeLong(10000);
dos.writeFloat(12.34F);
dos.writeDouble(12.56);

//释放资源
dos.close();
}
