Java Get Minimum Value in ArrayList

Tags: ArrayList

In this Java core tutorial we learn how to use the java.util.Collections class to get the minimum element in the java.util.ArrayList object in Java programming language.

How to get minimum element of ArrayList in Java

In Java, with a given ArrayList object we can use the Collections.min(Collection<? extends T> coll) static method to get the minimum element from the ArrayList as the following example Java code.

ArrayListMinValueExample1.java 

import java.util.ArrayList;
import java.util.Collections;
import java.util.List;

public class ArrayListMinValueExample1 {
    public static void main(String... args) {
        List<Double> list = new ArrayList<>();
        list.add(10.9);
        list.add(2.7);
        list.add(1.5);
        list.add(30.0);

        Double minValue = Collections.min(list);

        System.out.println("ArrayList: " + list);
        System.out.println("Minimum Value: " + minValue);
    }
}
The output as below. 
ArrayList: [10.9, 2.7, 1.5, 30.0]
Minimum Value: 1.5
