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
