The compareTo() method returns an integer: 0 if the strings are equal, a negative value if the calling string precedes the argument string, and a positive value if it follows. Basic Syntax: str1.compareTo(str2) In the syntax str1.compareTo(str2), str2 is the parameter. This express...
public interface Comparable<T> { public int compareTo(T o); } The compareTo method compares the receiving object with the specified object and returns a negative integer, 0, or a positive integer depending on whether the receiving object is less than, equal to, or greater than the specifie...
Contravariance is when this happens backward. You might anticipate that this could happen when the type parameter, T, is used only as input, and you’d be right. For example, the System namespace contains an interface called IComparable<T>, which has a single method call...
public interface IComparable { int CompareTo(Object obj); } The single method of this interface takes an object argument and returns an integer: 0 if the objects are equal, -1 if the argument is greater than the object that implements the interface, and 1 if the object that implements the...
