DataOutputStream WriteDouble() Example
Converts the double argument to a long using the doubleToLongBits method
DataOutputStreamclass WriteDouble() method example. This example shows you how to use WriteDouble() method.This method Converts the double argument to a long using the doubleToLongBits method in class Double, and then writes that long value to the underlying output stream as an 8-byte quantity, high byte first.
Here is the code:-
/**
* @Program that Converts the double argument to a long using the doubleToLongB
its method in class Double, and then writes that long value to the
underlying output stream
* WriteDouble.java

import java.io.*;
public class WriteDouble {
public static void main(String[] args)throws IOException {
double d=234;
FileOutputStream fos=new FileOutputStream("g.txt");
DataOutputStream dos=new DataOutputStream(fos);
//Converts the double argument to a long using the doubleToLongB
dos.writeDouble(d);
FileInputStream fis=new FileInputStream("g.txt");
DataInputStream dis=new DataInputStream(fis);
System.out.println("Double to the underlying output stream is : "+dis.readDouble());
}
} |
Output of the Program
| Double to the underlying output stream is : 234.0 |
