Hello,
Can anyone explain the output of the following program?
import java.io.*;
class ReadFloat {
public static void main (String args[]) throws java.io.IOException {
DataInputStream dis = new DataInputStream(System.in);
DataOutputStream dos = new DataOutputStream(System.out);
float fTest = dis.readFloat();
System.out.println("fTest = " + fTest);
dos.writeFloat(fTest);
String s = dis.readLine();
float f = Float.valueOf(s).floatValue();
System.out.println("f = " + f);
dos.writeFloat(fTest);
}
}
The output is:
=> 4.5
fTest = 1.62243e-007
4.5
=> 4.5
f = 4.5
4.5
Notice that the only one who seems to know what the heck readFloat()
is doing is writeFloat()!
Thanks,
