LongAdder class in Java creates a new adder with an initial sum of zero. The Java.LongAdder.sum() is an inbuilt method in java that returns the sum.
Syntax:
public long sum()
Parameters: The function does not accepts any parameter.
Return value: The method returns the current sum.
Program below demonstrates the function:
Below programs demonstrate the above function:
Program 1:
// Java program to demonstrate // the LongAdder.sum() method import java.lang.*;
import java.util.concurrent.atomic.LongAdder;
public class GFG {
public static void main(String args[])
{
// Initialized with 0
LongAdder num = new LongAdder();
// Print the initial value
System.out.println( "Initial value is: "
+ num);
// Add 6 to it
num.add( 6 );
// Print the final value
System.out.println( "After addition"
+ " of 6, value is: "
+ num);
// Add 5 to it
num.add( 5 );
// Print the final value
System.out.println( "After addition"
+ " of 5, value is: "
+ num);
// sum operation on num
num.sum();
// Print after sum
System.out.println( "Returned sum value is: "
+ num);
}
} |
Output:
Initial value is: 0 After addition of 6, value is: 6 After addition of 5, value is: 11 Returned sum value is: 11
Program 2:
// Java program to demonstrate // the LongAdder.sum() method import java.lang.*;
import java.util.concurrent.atomic.LongAdder;
public class GFG {
public static void main(String args[])
{
// Initialized with 0
LongAdder num = new LongAdder();
// Print the initial value
System.out.println( "Initial value is: "
+ num);
// Add 10 to it
num.add( 10 );
// Print the final value
System.out.println( "After addition"
+ " of 10, value is: "
+ num);
// Add 100 to it
num.add( 100 );
// Print the final value
System.out.println( "After addition"
+ " of 100, value is: "
+ num);
// sum operation on num
num.sum();
// Print after sum
System.out.println( "Returned sum value is: "
+ num);
}

Output:
Initial value is: 0 After addition of 10, value is: 10 After addition of 100, value is: 110 Returned sum value is: 110
