Description fommil 2008-04-02 21:56:57 UTC
NetBeans 6.1 Beta.

Consider the following (contrived) code

public class MyClass {
    public MyClass(){
    public MyClass foo(Object obj){
        return new MyClass(obj);

Currently, the hinter will offer to create a MyClass(Object) constructor... however, it is most often more useful to be able to add the parameter to the 
current constructor... i.e. offer to change MyClass() into MyClass(Object obj).

Created attachment 130204 [details]
Missing changed constructor

For example:
public class Foo {
        int a, b;
        public Foo(int a, int b) {
            this.a = a;
            this.b = b;

        public void method() {
            new Foo(1, 2, 3);

ACTUAL: hint "create constructor Foo(int, int, int)"

* add new hint "change constructor to Foo(int, int, int)"
* (and keep) hint "create constructor Foo(int, int, int)"

See attached screenshot
