Can I use annotation inside the method body?

Question

Allows the semantics of Java annotations to place them somewhere inside the body of functions , for example. annotate a specific function call, statement, or expression?

For instance:

class MyClass { void theFunc(Thing thing) { String s = null; @Catching(NullPointerException) //<< annotation ? s = thing.getProp().getSub().getElem().getItem(); if(s==null) System.out.println("null, you fool"); } } 

Shorten the often written (too often, definitely!):

 class MyClass { void theFunc(Thing thing) { String s = null; try { s = thing.getProp().getSub().getElem().getItem(); } catch(NullPointerException ex) { } if(s==null) System.out.println("null, you fool"); } } 

If the concept of this inline annotation is even possible? Or something similar?

Answer 1

ElementType indicates the actual purpose of the annotation. You cannot annotate any old expression. It essentially boiled down to declarations; ads:

• annotation type
• Constructor
• field
• Local variable
• method
• package
• parameter
• of type
