### Question:
LongString implements EncodableData { @Override public boolean equals(Object obj) { if (this == obj) { return true; } return (obj instanceof LongString) && (Arrays.equals(content, ((LongString) obj).content)); } @SuppressFBWarnings("EI_EXPOSE_REP2")  LongString(long length, byte[] content); static LongString parseString(String data); @Override long getSize(); @Override void write(ByteBuf buf); static LongString parse(ByteBuf buf); static LongString parse(byte[] data); @Override boolean equals(Object obj); boolean isEmpty(); @Override int hashCode(); @Override String toString(); @SuppressFBWarnings("EI_EXPOSE_REP") byte[] getBytes();  }### Answer:
@Test public void testEquals() throws Exception { LongString other = LongString.parseString("different string"); LongString similar = LongString.parseString(DEFAULT_DATA_STRING); Assert.assertTrue(DEFAULT_TEST_OBJECT.equals(DEFAULT_TEST_OBJECT), "equals() should return true for similar objects"); Assert.assertTrue(DEFAULT_TEST_OBJECT.equals(similar), "equals() should return true for similar objects"); Assert.assertFalse(DEFAULT_TEST_OBJECT.equals(other), "equals() should return false for different objects"); Assert.assertFalse(DEFAULT_TEST_OBJECT.equals(DEFAULT_DATA_STRING), "equals() should return false for different objects"); }
