Java AtomicLong doubleValue() Method

The doubleValue() method of java AtomicLong class returns the current value of this AtomicLong as a double after a widening primitive conversion.

Syntax

Returns

the numeric value represented by this object after conversion to type double.

Example 1

import java.util.concurrent.atomic.AtomicLong;
public class AtomicLongDoubleValueExample1 {
		public static void main (String [] args) {
		AtomicLong atomiclong = new AtomicLong();
		//Returns the initialized value as Double
		Double result = atomiclong.doubleValue();
		//Prints the double value off atomic long
		System.out.println(result);
	}
}

Test it Now

Output:

0.0

Example 2

import java.util.concurrent.atomic.AtomicLong;
public class AtomicLongDoubleValueExample2 {
	public static void main (String [] args) {
		AtomicLong atomiclong = new AtomicLong(123456L);
		//Returns the initialized value as Double
		Double result = atomiclong.doubleValue();
		//Prints the double value off atomic long
		System.out.println(result);
	}
}

Test it Now

Output:

123456.0

Example 3

import java.util.concurrent.atomic.AtomicLong;
public class AtomicLongDoubleValueExample3 {
	public static void main (String [] args) {
		AtomicLong atomiclong = new AtomicLong(-654321L);
		//Returns the initialized value as Double
		Double result = atomiclong.doubleValue();
		//Prints the double value off atomic long
		System.out.println(result);
	}
}

Test it Now

Output:

-654321

Example 4

import java.util.concurrent.atomic.AtomicLong;
public class AtomicLongDoubleValueExample4 {
		public static void main (String [] args) {
		AtomicLong atomiclong = new AtomicLong(-10);
		atomiclong.decrementAndGet();
		//Returns the initialized value as Double
		Double result = atomiclong.doubleValue();
		//Prints the double value off atomic long
		System.out.println(result);
	}
}
