AtomicReference類的toString()方法用於返回AtomicReference對象的當前值的String表示形式。
用法:
public String toString()
參數:此方法不接受任何內容。
返回值:此方法返回當前值的String表示形式。
以下示例程序旨在說明toString()方法:
程序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());
}
}
輸出:
Value = 1234.0
程序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());
}
}
輸出:
Value = GFG
