LongAdder class in Java creates a new adder with an initial sum of zero. The Java.LongAdder.add() is an inbuilt method in java that adds the given value.
Syntax:
public void add(long x)
Parameters: The function accepts a single parameter x that specifies the value to be added.
Return value: The method do not returns any value.
Below programs demonstrate the above function:
Program 1:
// Java program to demonstrate // the LongAdder.add() 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);
}
} |
Output:
Initial value is: 0 After addition of 6, value is: 6 After addition of 5, value is: 11
Program 2:
// Java program to demonstrate // the LongAdder.add() 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 -5 to it
num.add(- 5 );
// Print the final value
System.out.println( "After addition"
+ " of -5, value is: "
+ num);
}
} |
Output:
Initial value is: 0 After addition of 10, value is: 10 After addition of -5, value is: 5
