Method with single 'synchronized' block can be replaced with 'synchronized' method

Reports methods whose body contains a single synchronized statement. A lock expression for this synchronized statement must be equal to this for instance methods or [ClassName].class for static methods.

To improve readability of such methods, you can remove the synchronized wrapper and mark the method as synchronized.


public int generateInt(int x) { synchronized (this) { return 1; } }

After the quick-fix is applied:

public synchronized int generateInt(int x) { return 1; }
