Examples of org.eclipse.jdt.core.dom.MethodDeclaration

org.eclipse.jdt.core.dom.MethodDeclaration
Method declaration AST node type. A method declaration is the union of a method declaration and a constructor declaration. For JLS2:
```
 MethodDeclaration: [ Javadoc ] { Modifier } ( Type | void ) Identifier ( [ FormalParameter { , FormalParameter } ] ) {[ ] } [ throws TypeName { , TypeName } ] ( Block | ; ) ConstructorDeclaration: [ Javadoc ] { Modifier } Identifier ( [ FormalParameter { , FormalParameter } ] ) [throws TypeName { , TypeName } ] Block 
```
For JLS3, type parameters and reified modifiers (and annotations) were added:
```
 MethodDeclaration: [ Javadoc ] { ExtendedModifier } [ < TypeParameter { , TypeParameter } > ] ( Type | void ) Identifier ( [ FormalParameter { , FormalParameter } ] ) {[ ] } [ throws TypeName { , TypeName } ] ( Block | ; ) ConstructorDeclaration: [ Javadoc ] { ExtendedModifier } [ < TypeParameter { , TypeParameter } > ] Identifier ( [ FormalParameter { , FormalParameter } ] ) [throws TypeName { , TypeName } ] Block 
```
When a Javadoc comment is present, the source range begins with the first character of the "/**" comment delimiter. When there is no Javadoc comment, the source range begins with the first character of the first modifier keyword (if modifiers), or the first character of the "<" token (method, no modifiers, type parameters), or the first character of the return type (method, no modifiers, no type parameters), or the first character of the identifier (constructor, no modifiers). The source range extends through the last character of the ";" token (if no body), or the last character of the block (if body).

The FormalParameter is represented by a {@link SingleVariableDeclaration}.
