I try to pass my sketch name like a final but i don’t find a way to do that, is it possible ?
sketch name in my case is `call_class_itself.pde`but I try to find something more universel.
```auto
void setup() {
println(this.getClass().getSimpleName());
}
import rope.costume.R_Shape;
public class Test extends rope.costume.R_Shape {
final call_class_itself me;
// here the purpose to mke something universel
// final this.getClass().getSimpleName() me;
Test(PApplet pa) {
super(pa);
me = (call_class_itself) pa;
}
void truc(PApplet pa) {
me.beginShape(other);
}
}
void beginShape(PGraphics other) {
}
```

**beginShape()** is a PApplet method:
[Processing.GitHub.io/processing-javadocs/core/processing/core/PApplet.html#beginShape--](http://Processing.GitHub.io/processing-javadocs/core/processing/core/PApplet.html#beginShape--)
Therefore, field _me_ doesn’t need to be of derived datatype call\_class\_itself in order to access the **beginShape()** member.
A _me_ field of parent datatype PApplet would be just enough.

Java demands that all datatypes of its variables & functions to be already known at compile time, before the program is even run.
What you’re attempting to do above is to dynamically declare a field named _me_ w/ some datatype that’s still gonna be determined in the future at run time, when the program’s already been compiled & running.
Most Java can offer at run time is what is called reflection or introspection:
[Docs.Oracle.com/en/java/javase/11/docs/api/java.base/java/lang/reflect/package-summary.html](http://Docs.Oracle.com/en/java/javase/11/docs/api/java.base/java/lang/reflect/package-summary.html)
So we can attempt to access members of an object outside its apparent datatype.

Maybe I’m not clear, I write my custom Processing method like `beginShape(Pgraphics pg)` and when I try to call this one from a class write outside Processing, my sketch don’t find it and return an error, it’s reason why i need to call those methodes from the sketch, and if I want something universal I cannot write the sketch name directly, I need to something to finf the sketchname before… its clearest ?

`beginShape(other);` -\> Where is that field _other_ declared & initialized? 😕

You point the problem this one is from `rope.costume.R_Shape` the library. So it’s a reason why my little class don’t want read the method `beginShape(PGraphics other)`

What’s the name of that library? Where can I get it? 🤠

(remark: a small sketch to show the sketch name: )
```auto
String sketchName1;
void setup() {
size(600, 600);
background(0);
sketchName1 = this.getClass().getSimpleName();
println(sketchName1);
}
void draw() {
//
background(0);
text(sketchName1, 30, 30);
}
//
```

thx but, I know that it’s the first line of my code `println(this.getClass().getSimpleName());`my problem is transforme that in `final this.getClass().getSimpleName() me;` and that’s cannot be a String.

What do you mean by write (or written?) outside Processing? ✍
Do you mean a “.java” file by any chance? 🤔
B/c inside “.pde” files, the example below compiles OK: 👌
```auto
void setup() {
exit();
}
void beginShape(PGraphics other) {
}
class Test {
PGraphics other;
void truc(PApplet pa) {
beginShape(other);
}
}
```

I written 🙂 outside to mean the class parent is in a library. And in this case the class child cannot read the similar method write in the sketch like `beginShape(PGraphics other)`.

I’ve just expanded my previous minimum “.pde” example to include a “.java” file as well: ☕
## sketch\_190529a.pde:
```auto
void setup() {
new Test();
exit();
}
void beginShape(PGraphics other) {
}
class Test extends rope.costume.R_Shape {
void truc(PApplet pa) {
beginShape(other);
}
}
```
## R\_Shape.java:
```auto
package rope.costume;
import processing.core.PGraphics;
public class R_Shape {
public PGraphics other;
}
```
Like my previous example w/ just 1 “.pde” file, this 1 w/ both “.pde” & “.java” + `extends` compiles successfully as well. 🥳
Can you also provide us a minimum runnable sketch that demos the compile error you’re getting? 🤒

I cannot do more simple what I passed before, maybe the error is from dial between processing and library I suppose…are you try with my library ?

All my minimum runnable sketches have been based on your screenshot code! 🙄
But to prove once again your compile error doesn’t show up at all, here’s a “.pde” file exactly like your screenshot: ©
## call\_class\_itself.pde:
```auto
void setup() { }
import rope.costume.R_Shape;
class Test extends rope.costume.R_Shape {
Test(PApplet pa) {
super(pa);
}
void truc(PApplet pa) {
beginShape(other);
}
}
void beginShape(PGraphics other) {
}
```
And 3 minimum compilable “.java” files based (as much as I could) on your 3 original classes R\_Shape, R\_Image & BigBang from your library, following up all their inheritance chain: ☕
## R\_Shape.java:
```auto
package rope.costume;
import rope.core.*;
import processing.core.*;
public class R_Shape extends R_Image {
public R_Shape(PApplet pa) {
super(pa);
}
public R_Shape(PApplet pa, PGraphics other) {
super(pa, other);
}
}
```
## R\_Image.java:
```auto
package rope.core;
import processing.core.*;
public class R_Image extends BigBang {
protected processing.core.PGraphics other;
public R_Image(PApplet pa) {
super(pa);
}
public R_Image(PApplet pa, PGraphics other) {
super(pa);
this.other = other;
}
}
```
## BigBang.java:
```auto
package rope.core;
import processing.core.*;
public abstract class BigBang {
public PApplet pa;
public BigBang() {
}
public BigBang(PApplet pa) {
this.pa = pa;
}
}
```
Unless you could come up w/ some actually runnable code like mine above, that proves your compilable error does happen, I can’t help you anymore, sorry. 😖
