Effect of the Synchronized Keyword
< Prev
Next >

Consider the SyncCheck class provided below. What is the effect of the synchronized keyword on the updateValue method?

public class SyncCheck {
    private int value = 0;
    
    public synchronized void updateValue(int newVal) {
        if(newVal > value) {
            value = newVal;
        }
    }
    
    public int getValue() {
        return value;
    }
    
    public static void main(String[] args) {
        SyncCheck sc = new SyncCheck();
        Runnable task = () -> { sc.updateValue((int)(Math.random()*100)); };
        Thread t1 = new Thread(task);
        Thread t2 = new Thread(task);
        t1.start();
        t2.start();
    }
}
A

It ensures that the if condition always evaluates to true, allowing safe updates.

B

It prevents deadlock by avoiding nested synchronization scenarios.

C

It ensures that only one thread can execute updateValue at a time, preventing concurrent race conditions.

D

It guarantees that the value’s read and update operations are inherently atomic even outside the method.
