### Question:
Decimal implements EncodableData { @Override public boolean equals(Object obj) { if (this == obj) { return true; } return (obj instanceof Decimal) && (value.equals(((Decimal) obj).value)); } private  Decimal(BigDecimal value); @Override long getSize(); @Override void write(ByteBuf buf); static Decimal parse(BigDecimal value); static Decimal parse(ByteBuf buf); BigDecimal getDecimal(); @Override int hashCode(); @Override boolean equals(Object obj); @Override String toString();  }### Answer:
@Test public void testEquals() { Decimal other = Decimal.parse(new BigDecimal(3.0d)); Decimal similar = Decimal.parse(DATA_VALUE); Assert.assertTrue(TEST_OBJECT.equals(TEST_OBJECT), "equals() should return true for similar objects"); Assert.assertTrue(TEST_OBJECT.equals(similar), "equals() should return true for similar objects"); Assert.assertFalse(TEST_OBJECT.equals(other), "equals() should return false for different objects"); Assert.assertFalse(TEST_OBJECT.equals(DATA_VALUE), "equals() should return false for different objects"); }
