Rule:  Design27Checked automatically with code checker

Synopsis:Use block level rather than method level synchronization
Language:Java
Severity Level:3
Category:Design


Description:
Method level synchronization can backfire when new code is added to the method. Block-level synchronization helps to ensure that only the code that needs synchronization gets it.
public class Foo {
 // Try to avoid this
 synchronized void foo() {
 }
 // Prefer this:
 void bar() {
  synchronized(this) {
  }
 }
}
