Last Updated :

The get() method of a AtomicReferenceArray class is used to return the value of the element at index i for this AtomicReferenceArray object with memory semantics of reading as if the variable of index was declared volatile type of variable.
Syntax:
public final E get(int i)
Parameters: This method accepts the index i to get the value.
Return value: This method returns current value at index i.
Below programs illustrate the get() method:
Program 1:
import java.util.concurrent.atomic.AtomicReferenceArray;
public class GFG {
public static void main(String[] args)
{
AtomicReferenceArray<Integer> array
= new AtomicReferenceArray<Integer>( 5 );
array.set( 0 , 12 );
array.set( 1 , 13 );
array.set( 2 , 14 );
array.set( 3 , 15 );
for ( int i = 0 ; i < 4 ; i++) {
int value = array.get(i);
System.out.println( "value at "
+ i + " = " + value);
}
}
}
|
Output:
value at 0 = 12
value at 1 = 13
value at 2 = 14
value at 3 = 15
Program 2:
import java.util.concurrent.atomic.AtomicReferenceArray;
public class GFG {
public static void main(String[] args)
{
AtomicReferenceArray<String> array
= new AtomicReferenceArray<String>( 5 );
array.set( 0 , "AMAN" );
array.set( 1 , "AMAR" );
for ( int i = 0 ; i < 2 ; i++) {
String value = array.get(i);
System.out.println( "value at "
+ i + " = " + value);
}
}
}
|
Output:
value at 0 = AMAN
value at 1 = AMAR
