  • Last Updated : 27 Dec, 2019

The toString() method of a AtomicReference class is used to return the String representation of the current value of AtomicReference object.

Syntax:

public String toString()

Parameters: This method accepts nothing.

Return value: This method returns the String representation of the current value.

Below programs illustrate the toString() method:
Program 1:






// Java program to demonstrate
// AtomicReference.toString() method
  
import java.util.concurrent.atomic.AtomicReference;
  
public class GFG {
    public static void main(String[] args)
    {
  
        // create an atomic reference object.
        AtomicReference<Double> ref
            = new AtomicReference<Double>();
  
        // set some value
        ref.set(1234.00);
  
        // apply toString()
        System.out.println("Value = "
                           + ref.toString());
    }
}
Output:
Value = 1234.0

Program 2:




// Java program to demonstrate
// AtomicReference.toString() method
  
import java.util.concurrent.atomic.AtomicReference;
  
public class GFG {
    public static void main(String[] args)
    {
  
        // create an atomic reference object
        // which stores String.
        AtomicReference<String> ref
            = new AtomicReference<String>();
  
        // set some value
        ref.set("GFG");
  
        // apply toString()
        System.out.println("Value  = "
                           + ref.toString());
    }
}
Output:
Value  = GFG
