When are initializations outside a constructor called?

Question

Suppose I have

class MyObject
{
    Object object1 = new Object();
    Object object2;

    public MyObject()
    {
        object2 = new Object();
    }

If you want to confirm behavior, use javap or a similar tool to inspect the bytecode. Though Jon is correct, refer to the specification as a first port of call.

Compiled from "MyObject.java"
class MyObject {
  java.lang.Object object1;

  java.lang.Object object2;

  public MyObject();
    Code:
       0: aload_0
       1: invokespecial #11               // Method java/lang/Object."":()V
       4: aload_0
       5: new           #3                // class java/lang/Object
       8: dup
       9: invokespecial #11               // Method java/lang/Object."":()V
      12: putfield      #13               // Field object1:Ljava/lang/Object;
      15: aload_0
      16: new           #3                // class java/lang/Object
      19: dup
      20: invokespecial #11               // Method java/lang/Object."":()V
      23: putfield      #15               // Field object2:Ljava/lang/Object;
      26: return
