The java.util.concurrent.atomic.AtomicInteger.doubleValue() is an inbuilt method in java which returns the current value of the AtomicInteger as a Double data-type after performing primitive conversion.
Syntax:
public double doubleValue()
Parameters: The function does not accepts any parameter.
Return value: The function returns the numeric value represented by this object after conversion to type double.
Program below demonstrates the function:
Program 1:
// Java Program to demonstrates // the doubleValue() function import java.util.concurrent.atomic.AtomicInteger;
public class GFG {
public static void main(String args[])
{
// Initially value as 0
AtomicInteger val
= new AtomicInteger( 0 );
val.addAndGet( 7 );
// Prints the updated value
System.out.println( "Previous value: "
+ val);
// Gets the double value
double res = val.doubleValue();
System.out.println( "Double value: "
+ res);
}
} |
Output:
Previous value: 7 Double value: 7.0
// Java Program to demonstrates // the doubleValue() function import java.util.concurrent.atomic.AtomicInteger;
public class GFG {
public static void main(String args[])
{
// Initially value as 18
AtomicInteger val
= new AtomicInteger( 18 );
val.addAndGet( 7 );
// Gets the double value
System.out.println( "Previous value: "
+ val);
// Decreases the value by 1
double res = val.doubleValue();
System.out.println( "Double value: "
+ res);
}
} |
Output:
Previous value: 25 Double value: 25.0
