Both == and .equals methods are there for reference comparison only. It means whether both objects are referring to same object or not. Equals Full Day Conference - 14 – 25 Education – What does Independence mean for young people with PMLD, SLD and MLD – Practical Solutions and Possibilities Note that it is generally necessary to override the hashCode method whenever this method is overridden, so as to maintain the general contract for the hashCode method, which states that equal objects must have equal hash codes.

And to avoid the tedious repetition of these words: "is equal to" I will set as I do often in work use, a pair of parallels, or duplicate lines of one [the same] length, thus: =, because no 2 things can be more equal.

The equals() method compares the "value" inside String instances (on the heap) irrespective if the two object references refer to the same String instance or not. If any two object references of type String refer to the same String instance then great! If the two object references refer to two different String instances .. it doesn't make a difference. Its the "value" (that is: the contents of the character array) inside each String instance that is being compared. In the second comparison, we are using the operator “==” for comparing the String Objects and not the contents of the objects. Here, both the objects are different, and hence the outcome of this comparison is “False.” In case of String, there is one more usecase. Here when we assign any string to String reference then string constant is created inside String constant pool. If we assign same string to new String reference then no new string constant is created rather it will refer to existing string constant. public class HelloWorld{ Hartell, Rhonda L., ed. (1993). The Alphabets of Africa. Dakar: UNESCO and SIL . Retrieved 19 October 2013. Many of them say that for comparing string you should use equals and not ==. Hope in this answer I will be able to say the difference.If a class does not override the equals method, then it defaults to the equals(Object o) method of the closest parent class that has overridden this method. However, the == operator will still return results based on the memory location of the two objects(person1 and person2). Foster high quality innovation practice, through the publication of relevant and rigorous support materials.

The triple bar symbol ≡ (U+2261, LaTeX \equiv) is often used to indicate an identity, a definition (which can also be represented by U+225D ≝ EQUAL TO BY DEFINITION or U+2254 ≔ COLON EQUALS), or a congruence relation in modular arithmetic. On the other hand, the "==" operator compares the value of two object references to see whether they refer to the same String instance. If the value of both object references "refer to" the same String instance then the result of the boolean expression would be "true"..duh. If, on the other hand, the value of both object references "refer to" different String instances (even though both String instances have identical "values", that is, the contents of the character arrays of each String instance are the same) the result of the boolean expression would be "false".Weisstein, Eric W.

Peter Debruge of Variety, giving the film a positive review, said "Kristen Stewart and Nicholas Hoult play citizens living in an emotion-free future who struggle to understand the attraction they feel for one another in this stylish, if simplistic sci-fi romance." [22] IndieWire gave the film a C−, writing that "the real wonder and marvel and breathless mystery of Equals may be that something so dazzlingly white can be so very dull." [23] See also [ edit ]
