The length() method of a AtomicReferenceArray class is used to return the length of this AtomicReferenceArray.
Syntax:
public final int length()
Parameters: This method accepts nothing.
Return value: This method returns the integer representing length of this AtomicReferenceArray.
Below programs illustrate the length() method:
Program 1:
// Java program to demonstrate // AtomicReferenceArray.length() method import java.util.concurrent.atomic.*;
public class GFG {
public static void main(String[] args)
{
// create an atomic reference object.
AtomicReferenceArray<Integer> ref
= new AtomicReferenceArray<Integer>( 5 );
// print the length
int length = ref.length();
System.out.println(
"length of AtomicReferenceArray = "
+ length);
}
} |
Output:
length of AtomicReferenceArray = 5
Program 2:
// Java program to demonstrate // AtomicReferenceArray.length() method import java.util.concurrent.atomic.*;
public class GFG {
public static void main(String[] args)
{
// create a array of Strings
String[] names
= { "AMAN" , "AMAR" , "SURAJ" };
// create an atomic reference object.
AtomicReferenceArray<String> ref
= new AtomicReferenceArray<String>(names);
// print the length
int length = ref.length();
System.out.println(
"length of AtomicReferenceArray = "
+ length);
}
} |
Output:
length of AtomicReferenceArray = 3
