You should write a class that implements Comparator<String> for this. A quick approach using anonymous class: String a = s.min(list, new Comparator<String>() { @Override public int compare(String s1, String s2) { return s1.compareTo(s2); } });

Apr 16, 2025 · The Comparator interface in Java is used to sort the objects of user-defined classes. The Comparator interface is present in java.util package. This interface allows us to define custom comparison logic outside of the class for which instances we want to sort.

Mar 26, 2025 · Let’s see a quick example of how to use a lambda expression to create a Comparator: Comparator byRanking = (Player player1, Player player2) -> Integer.compare(player1.getRanking(), player2.getRanking());

An object that implements the Comparator interface is called a comparator. The Comparator interface allows you to create a class with a compare() method that compares two objects to decide which one should go first in a list. The compare() method should return a number which is: Negative if the first object should go first in a list.

Dec 5, 2013 · Comparator<Test> comparator = new Comparator<Test>() { @Override. public int compare(Test o1, Test o2) { int res = o1.getDescription().compareTo(o2.getDescription()); if (res == 0) return o1.getPriority() < o2.getPriority() ? -1 : 1; else. return res; }; Collections.sort(testList, comparator); List<String> valoriInseriti = new ArrayList<>();

I'm trying to make a comparator that can take any type of an element to compare. I'm unsure about how to create the class. I just want it to compare two elements of the same type (But whatever type the client gives it, ex: Integer, String, Double, etc...) to see which one is greater then the other. * Compares two elements.

Jan 4, 2022 · Java Comparator interface is used to sort an array or List of objects based on custom sort order. The custom ordering of items is imposed by implementing Comparator’s compare() method in the objects.

Feb 6, 2023 · Learn to create a Comparator instance with lambda expressions, method references and chaining multiple comparators for complex comparisons. The Comparator interface is used to sort a collection of objects that can be compared.

In this article, we will discuss how to use the Comparator interface in Java to compare and sort objects. We will cover various ways to implement the Comparator interface and provide examples to demonstrate its usage. The Comparator interface in Java is used to define a custom comparison logic for objects.

Dec 17, 2024 · To use a Comparator, you implement its compare() method. This method takes two arguments of the type you want to compare and returns: A negative integer if the first argument is less than the second. Zero if the two arguments are equal. A positive integer if the first argument is greater than the second. private String name; private int age;
