### Question:
SwappedDataInputStream extends ProxyInputStream implements DataInput { public float readFloat() throws IOException, EOFException { return EndianUtils.readSwappedFloat( in ); } SwappedDataInputStream( final InputStream input ); boolean readBoolean(); byte readByte(); char readChar(); double readDouble(); float readFloat(); void readFully( final byte[] data ); void readFully( final byte[] data, final int offset, final int length ); int readInt(); String readLine(); long readLong(); short readShort(); int readUnsignedByte(); int readUnsignedShort(); String readUTF(); int skipBytes( final int count );  }### Answer:
@Test public void testReadFloat() throws IOException { assertEquals( Float.intBitsToFloat(0x04030201), this.sdis.readFloat(), 0 ); }
