AtomicInteger represents an int value that may be updated atomicallyAn atomic operation is performing a single unit of work on a resource. During that operation, no other operations are allowed on the same resource until the performing operation is finished.. The AtomicInteger class is present in the java.util.concurrent.atomic package.

The floatValue method of the AtomicInteger class will return the AtomicInteger value as a float value after a widening primitive conversion.

Syntax

public float floatValue()

Paramater

This method doesn’t take any arguments.

Return value

This method returns the AtomicInteger object’s value as a float value.

Code

The below code demonstrates how to use the floatValue method:

import java.util.concurrent.atomic.AtomicInteger;
class FloatValue{
public static void main(String[] args) {
AtomicInteger atomicInteger = new AtomicInteger(10);
int val = atomicInteger.get();
System.out.println("The value in the atomicInteger object is " + val);
float floatVal = atomicInteger.floatValue();
System.out.println("\natomicInteger.floatValue() : " + floatVal);
}
}
Example of AtomicInteger.floatValue()

Explanation

In line 1: We imported the AtomicInteger class.

In line 4: We created a new object for the AtomicInteger class with the name atomicInteger and with the value 10.

In line number 9: We used the floatValue method to get the value of the atomicInteger object as a float value.
