Java IO Tutorial - Java ObjectInputStream.readFloat()








Syntax

ObjectInputStream.readFloat() has the following syntax.

public float readFloat()  throws IOException

Example

In the following code shows how to use ObjectInputStream.readFloat() method.

/*  ww  w .j  a  v  a  2  s .  co  m*/
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;

public class Main {

  public static void main(String[] args) throws Exception {

    float f = 1.23456f;

    FileOutputStream out = new FileOutputStream("test.txt");
    ObjectOutputStream oout = new ObjectOutputStream(out);


    oout.writeFloat(f);
    oout.writeFloat(1234.56789f);
    oout.flush();
    oout.close();
    
    ObjectInputStream ois = new ObjectInputStream(new FileInputStream(
        "test.txt"));

    System.out.println(ois.readFloat());

    System.out.println(ois.readFloat());
    ois.close();
  }
}

The code above generates the following result.
