How to find Sum, Min, Max of Integer using Java 8 stream?

Solution:-

package p3;

import java.util.Arrays;

import java.util.List;

public class SumMinMaxOfInteger {

  public static void main(String[] args) {

    List<Integer> list=Arrays.asList(10,40,50);

    Integer sum=list.stream().mapToInt(i->i).sum();

    System.out.println("Sum of elements:"+sum);

    

    Integer min=list.stream().mapToInt(i->i).min().getAsInt();

    System.out.println("Min of elements:"+min);

    

    Integer max=list.stream().mapToInt(i->i).max().getAsInt();

    System.out.println("Max of Integer:"+max);

    

 }

 }
