The java.util.concurrent.atomic.AtomicInteger.incrementAndGet() is an inbuilt method in java that increases the previous value by one and returns the value after updation which is of data-type int.
Syntax:
public final int incrementAndGet()
Parameters: The function does not accepts a single parameter.
Return value: The function returns the value after increment operation is performed to the previous value.
Program below demonstrates the function:
Program 1:
Java
import java.util.concurrent.atomic.AtomicInteger;
public class GFG {
public static void main(String args[])
{
AtomicInteger val
= new AtomicInteger( 0 );
System.out.println( "Previous value: "
+ val);
int res
= val.incrementAndGet();
System.out.println( "Current value: "
+ res);
}
}
|
Output:
Previous value: 0
Current value: 1
Program 2:
Java
import java.util.concurrent.atomic.AtomicInteger;
public class GFG {
public static void main(String args[])
{
AtomicInteger val
= new AtomicInteger( 18 );
System.out.println( "Previous value: "
+ val);
int res = val.incrementAndGet();
System.out.println( "Current value: "
+ res);
}
}
