###

This interface defines the methods required for streams that can write character data or 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 abstract interface DataOutput {
        // Public Instance Methods
                public abstract void write(int b) throws IOException;
                public abstract void write(byte[] b) throws IOException;
                public abstract void write(byte[] b, int off, int len) throws IOException;
                public abstract void writeBoolean(boolean v) throws IOException;
                public abstract void writeByte(int v) throws IOException;
                public abstract void writeBytes(String s) throws IOException;
                public abstract void writeChar(int v) throws IOException;
                public abstract void writeChars(String s) throws IOException;
                public abstract void writeDouble(double v) throws IOException;
                public abstract void writeFloat(float v) throws IOException;
                public abstract void writeInt(int v) throws IOException;
                public abstract void writeLong(long v) throws IOException;
                public abstract void writeShort(int v) throws IOException;
                public abstract void writeUTF(String str) throws IOException;
