### Question:
Value { public boolean cmp(Value o) { if (o == null) { return false; } if (rlp != null && o.rlp != null) { return Arrays.equals(rlp, o.rlp); } else { return Arrays.equals(this.encode(), o.encode()); } } private  Value();  Value(Object obj); static Value fromRlpEncoded(byte[] data); Object asObj(); List<Object> asList(); int asInt(); long asLong(); BigInteger asBigInt(); String asString(); byte[] asBytes(); byte[] getData(); Value get(int index); byte[] encode(); boolean cmp(Value o); boolean isList(); boolean isString(); boolean isBytes(); boolean isHashCode(); boolean isNull(); int length(); String toString();  }### Answer:
@Test public void testCmp() { Value val1 = new Value("hello"); Value val2 = new Value("world"); assertFalse("Expected values not to be equal", val1.cmp(val2)); Value val3 = new Value("hello"); Value val4 = new Value("hello"); assertTrue("Expected values to be equal", val3.cmp(val4)); Value inter = new Value(new Object[] {1}); Object[] interExp = new Object[] {1}; assertTrue(new Value(inter.asObj()).cmp(new Value(interExp))); String dog = "dog"; Value val5 = new Value(dog); Value val6 = Value.fromRlpEncoded(Hex.decode("83646f67")); assertThat(val5.cmp(val6)).isTrue(); val5 = Value.fromRlpEncoded(Hex.decode("83646f67")); assertThat(val5.cmp(val6)).isTrue(); val5 = Value.fromRlpEncoded(Hex.decode("83636174")); assertThat(val5.cmp(val6)).isFalse(); assertThat(val6.cmp(null)).isFalse(); }
