Java 中的 AtomicReferenceArray length()方法，示例
原文:https://www . geeksforgeeks . org/atomicreferencearray-length-method-in-Java-with-examples/
一个原子引用数组类的 length() 方法用来返回这个原子引用数组的长度。
语法:
public final int length()
参数:此方法不接受任何内容。
返回值:该方法返回表示该原子数组长度的整数。
下面的程序说明了 length()方法: 程序 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
程序 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
