Field assignment can be moved to initializer

Suggests replacing initialization of fields using assignment with initialization in the field declaration.

Only reports if the field assignment is located in an instance or static initializer, and joining it with the field declaration is likely to be safe. In other cases, like assignment inside a constructor, the quick-fix is provided without highlighting, as the fix may change the semantics.

Example:

  class MyClass {
    static final int intConstant;
    
    static {
      intConstant = 10;
    }
  }

The quick fix moves the assigned value to the field initializer removing the class initializer if possible:

  class MyClass {
    static final int intConstant = 10;
  }
