Java Static code block execution analysis

Source: Internet
Author: User

Suppose you have a class like this:

public class Utils {
Static {
LOG.I ("Static", "isload!");
}
Public  static  void Staticcode () {

}

public  int value;

public void Nostaticcode () {

}

}

When will the static code block be loaded when the whole program is running?
1. When instantiating the class. Column: New Utils ();
2. When the class static method is called. Column: Utils.staticcode ();
Summary: When calling a class with a static code block, the static code block is executed first and is called only once.
