IntSummaryStatistics getSum() method in Java with Examples

The Java IntSummaryStatistics class's getSum() function is used to retrieve the total number of records in this IntSummaryStatistics.

Syntax:

Parameter: There are no values that can be passed as parameters to this method.

Return Value: The total of the records in this IntSummaryStatistics is returned by this method.

Example 1:

To find the sum of all the elements in an integer stream, utilize the IntSummaryStatistics class as demonstrated by the following Java program.

Implementation:

FileName: IntSummaryExample1.java

import java.util.IntSummaryStatistics;
import java.util.stream.IntStream;
import java.io.*;
public class IntSummaryExample1
{
    
    // main method
    public static void main(String[] args) 
    {
        // Construct an integer stream.
        IntStream intStream = IntStream.of(11, 22, 33, 44, 55, 66, 77, 88, 99, 100);
        // Utilize the stream to create an IntSummaryStatistics.
        IntSummaryStatistics stats = intStream.summaryStatistics();
        // Compute the integers in the stream added together.
        long sum = stats.getSum();
        System.out.println("The Sum of the values of the intstream is given by : " + sum);
    }
}

Output:

The Sum of the values of the intstream is given by : 595

Example 2:

Using the IntSummaryStatistics class, the Java program given determines the sum of the elements in a list of integers.

Implementation:

FileName: IntSummaryExample2.java

import java.io.*;
import java.util.*; 
public class IntSummaryExample2 
{ 
	// main method
	public static void main(String[] args) 
	{ 
		// creating object
		IntSummaryStatistics sumStatistics = new IntSummaryStatistics(); 
		List<Integer> my_list 	= Arrays.asList(11, 22, 33, 44, 55, 66, 77, 88, 99, 100); 
		Iterator<Integer> it = my_list.listIterator(); 
		while (it.hasNext()) 
		{ 
			// Enhance the adding of integers in the IntSummaryStatistics object.
			sumStatistics.accept(it.next()); 
		} 
		System.out.println("The sum of the values of the array is " + sumStatistics.getSum()); 
	} 
}

Output:

The sum of the values of the array is 595
