This interface defines the methods required for streams that can write Java primitive data types in a machine-independent binary format. It is implemented by DataOutputStream and RandomAccessFile. See DataOutputStream for more information on the methods.

public interface DataOutput {
// Public Instance Methods
     void write(byte[ ] b) throws IOException;  
     void write(int b) throws IOException;  
     void write(byte[ ] b, int off, int len) throws IOException;  
     void writeBoolean(boolean v) throws IOException;  
     void writeByte(int v) throws IOException;  
     void writeBytes(String s) throws IOException;  
     void writeChar(int v) throws IOException;  
     void writeChars(String s) throws IOException;  
     void writeDouble(double v) throws IOException;  
     void writeFloat(float v) throws IOException;  
     void writeInt(int v) throws IOException;  
     void writeLong(long v) throws IOException;  
     void writeShort(int v) throws IOException;  
     void writeUTF(String str) throws IOException;
