The equals() method compares two strings , and returns true if the strings are equal, and false if not.
Read moreWhat is the difference between == and the equals () method?
In simple words, == checks if both objects point to the same memory location whereas . equals() evaluates to the comparison of values in the objects . If a class does not override the equals method, then by default, it uses the equals(Object o) method of the closest parent class that has overridden this method.
Read moreDoes every Object have a toString method and an equal method?
This is how every class has a toString() method : since Object has a toString() method, then ‘children’ of Object inherit a toString() method, the children of children of Object inherit a toString() method, and so on. So every class ‘automatically’ gets a toString() method by inheritance.
Read moreHow do you equal two objects?
The equals() method of the Object class compare the equality of two objects. The two objects will be equal if they share the same memory address . Syntax: public boolean equals(Object obj)
Read moreCan objects be equal to each other?
Since computing an object’s equality is a time-consuming task, Java also provides a quick way of determining if an object is equal or not, using hashCode() . This returns a small number based on the object’s internal datastructure; if two objects have different hash codes, then they cannot be equal to each other .
Read moreWhat is the use of equals method of Object class?
The equals method for class Object implements the most discriminating possible equivalence relation on objects ; that is, for any non-null reference values x and y, this method returns true if and only if x and y refer to the same object (x == y has the value true).
Read moreHow do you identify unique objects in Java?
When a class in Java doesn’t override hashCode(), printing an instance of this class gives a nice unique number. The Javadoc of Object says about hashCode(): As much as is reasonably practical, the hashCode method defined by class Object does return distinct integers for distinct objects .
