hi
i this example :
Thread thread = new Thread("New Thread") {
public void run(){
System.out.println("run by: " + getName());
}
};

thread.start();
System.out.println(thread.getName());

i need to get all method in block
new Thread("New Thread") {
public void run(){
System.out.println("run by: " + getName());
}
};

in my example all method in block of new Thread in run();

i can to get new Thread("New Thread") by Expression using the following code :
Expression expression = node.getExpression();
if (expression != null) {
System.out.println("Expr: " + expression.toString());

ITypeBinding typeBinding = expression.resolveTypeBinding();
if (typeBinding != null) {
System.out.println("Type: " + typeBinding.getName());
}
}

how can to get the block of new Thread("New Thread") { }

If you already succeeded to navigate to the expression in question, you probably also noticed that this expression has type ClassInstanceCreation. Please see that this class has a method getAnonymousClassDeclaration(). From there, bodyDeclarations() takes you to the list of declarations between '{' and '}'.

I recommend you install ASTView[1] which let's you inspect the AST corresponding to any source you are editing in the Java editor.
