The Java.DoubleAccumulator.intValue() is an inbuilt method in java that returns the current value as an int after a narrowing primitive conversion. The initial datatype is double which is explicitly converted into type int without accepting any parameters.
Syntax:
public int intValue()
Parameters: The method does not accepts any parameter.
Return Value: The method returns the current value as an int after a narrowing primitive conversion.
Below programs illustrate the above method:
Program 1:
// Java program to demonstrate// intValue() method  import java.lang.*;import java.util.concurrent.atomic.DoubleAccumulator;  public class GFG {    public static void main(String args[])    {          DoubleAccumulator num            = new DoubleAccumulator(                Double::sum, 0L);          // accumulate operation on num        num.accumulate(42);        num.accumulate(10);          // Print before intValue operation        System.out.println("Old value is: "                           + num);          // Print after intValue operation        System.out.println("Current int value is: "                           + num.intValue());    }} |
Output:
Old value is: 52.0 Current int value is: 52
Program 2:
// Java program to demonstrate// intValue() method  import java.lang.*;import java.util.concurrent.atomic.DoubleAccumulator;  public class GFG {    public static void main(String args[])    {          DoubleAccumulator num            = new DoubleAccumulator(                Double::sum, 0L);          // accumulate operation on num        num.accumulate(63);        num.accumulate(1);          // Print before intValue operation        System.out.println("Old value is: "                           + num);          // Print after intValue operation        System.out.println("Current int value is: "                           + num.intValue());    }} |
Output:
Old value is: 64.0 Current int value is: 64
