Does compareTo return an integer?
Java Integer compareTo() method
This method compares two integer objects numerically. It returns the result of the value 0 if Integer is equal to the argument Integer, a value less than 0 if Integer is less than the argument Integer and a value greater than 0 if Integer is greater than the argument Integer.
How does the compareTo method work?

Why equals method used for?
The equals method in Java is invoked every time an object is compared with another object to see if they are equivalent to each other or not i.e. are they the same object in terms of data type and value.
Why do we need hashCode and equals method in Java?
The equals() and hashcode() are the two important methods provided by the Object class for comparing objects. Since the Object class is the parent class for all Java objects, hence all objects inherit the default implementation of these two methods.
What is difference between == equals () and compareTo () method?
The equals() tells the equality of two strings whereas the compareTo() method tell how strings are compared lexicographically.
What is compareTo C#?

Why is it said that the length () method of string class doesn’t return accurate results?
length() is not returning code points or that it is not a linguistically correct character count. It is measuring the length of the string using the model that is appropriate to the task at hand.
What method does return true if target string is containing search string provided in the argument?
