How to add newline in a textfile using dataouputstream in java

[C.R.Ram Kumar]

Hi

Any one can solve my problem

I want to add a new line in my textfile using dataoutputstream.

It is possible ?

public class dataIO {
 
    public static void main(String[] args) {
      
        int cityIdA = 1;
        String cityNameA = "Green Lake City";
        int cityPopulationA = 500000;
        float cityTempA = 15.50f;
 
        int cityIdB = 2;
        String cityNameB = "Salt Lake City";
        int cityPopulationB = 250000;
        float cityTempB = 10.45f;
 
        try {
         
            File file=new File("cities.txt");
            FileOutputStream fos = new FileOutputStream(file);
            DataOutputStream dos = new DataOutputStream(fos);
            FileWriter fw=new FileWriter(file);
            BufferedWriter out=new BufferedWriter(fw);
            
    
            dos.writeInt(cityIdA);
            dos.writeUTF(cityNameA);
            dos.writeInt(cityPopulationA);
            dos.writeFloat(cityTempA);

 // I want to add a newline here only [/b]

            dos.writeInt(cityIdB);
            dos.writeUTF(cityNameB);
            dos.writeInt(cityPopulationB);
            dos.writeFloat(cityTempB);
 
            dos.flush();
            dos.close();
 
          
            FileInputStream fis = new FileInputStream("cities.txt");
            DataInputStream dis = new DataInputStream(fis);
 
         
            int cityId1 = dis.readInt();
            System.out.println("Id: " + cityId1);
            String cityName1 = dis.readUTF();
            System.out.println("Name: " + cityName1);
            int cityPopulation1 = dis.readInt();
            System.out.println("Population: " + cityPopulation1);
            float cityTemperature1 = dis.readFloat();
            System.out.println("Temperature: " + cityTemperature1);
 
            int cityId2 = dis.readInt();
            System.out.println("Id: " + cityId2);
            String cityName2 = dis.readUTF();
            System.out.println("Name: " + cityName2);
            int cityPopulation2 = dis.readInt();
            System.out.println("Population: " + cityPopulation2);
            float cityTemperature2 = dis.readFloat();
            System.out.println("Temperature: " + cityTemperature2);
        } catch (IOException e) {
            e.printStackTrace();
        }    }
}

Thank You . .

Hi C.R.Ram Kumar Welcome to JavaRanch.

DataOutputStream writes binary files. If you want to insert new line then you must have to use Writer.
