AtomicReferenceArray set() method in Java with Examples
Last Updated :

The set() method of a AtomicReferenceArray class is used to set the value of the element at index i to newValue. Both index i and newValue are passed as parameters to the method. This method set the value with memory semantics of reading as if the variable was declared volatile type of variable.
Syntax:
public final void set(int i, E newValue)
Parameters: This method accepts:
- i which is an index of AtomicReferenceArray to perform the operation,
- newValue which is the new value to set.
Return value: This method returns nothing.
Below programs illustrate the set() method:
Program 1:
import java.util.concurrent.atomic.*;
public class GFG {
public static void main(String[] args)
{
AtomicReferenceArray<Integer> ref
= new AtomicReferenceArray<Integer>( 5 );
ref.set( 0 , 2345 );
ref.set( 1 , 543 );
ref.set( 2 , 322 );
System.out.println( "Value of index 0 = "
+ ref.get( 0 ));
System.out.println( "Value of index 1 = "
+ ref.get( 1 ));
System.out.println( "Value of index 2 = "
+ ref.get( 2 ));
}
}
|
Output:
Value of index 0 = 2345
Value of index 1 = 543
Value of index 2 = 322
Program 2:
import java.util.concurrent.atomic.*;
public class GFG {
public static void main(String[] args)
{
AtomicReferenceArray<String> ref
= new AtomicReferenceArray<String>( 5 );
ref.set( 0 , "C" );
ref.set( 1 , "PYTHON" );
ref.set( 2 , "TS" );
ref.set( 3 , "C++" );
ref.set( 4 , "C" );
for ( int i = 0 ; i < 5 ; i++) {
System.out.println(ref.get(i));
}
}
}

Output:
C
PYTHON
TS
