How to check EOF in Binary File

[camlearner]

In text file we use below to check EOF.

InputStreamReader os = new InputStreamReader(.........);
int ch;
while((ch=os.read()) != -1){ //Check whether EOF or not
  //Output Something
}

But in binary file i don't how to check EOF

DataInputStream os = new DataInputStream(.........);
System.out.println(os.readInt());
System.out.println(os.readFloat());

I don't how used loop to print content of file until EOF. Please tell me.
