Processing -> Java -- Can I ouput/view native java files.

timobrien

Hi, I would like to see java files for a Processing program. I am assuming since Processing runs on java there is a way to have processing generate code in Java. Thanks for your help. Tim

operating system?

preference for Mac.

The processing run command wraps your code into a little bit of Java and does a few other changes like converting color to int. The output of this stage is saved somewhere on the file system before being compiled as Java. On Linux it's in the /tmp directory, named after the sketch but with a big random suffix. I don't know about macs but have a look there first.

There's not a lot of difference between the pde and the Java tbh - most of the work is done by libraries. Depends what you're after.

for instance, a simple sketch:

void setup() {
  size(100, 100);
  noStroke();
}

void draw() {
  color c = #123456;
  ellipse(width / 2, height / 2, width / 2, width / 2);
}

becomes /tmp/sketch_jul21a8978331535202291499temp/sketch_jul21a.java

public void draw() {
  int c = 0xff123456;
  ellipse(width / 2, height / 2, width / 2, width / 2);
}
  static public void main(String args[]) {
    PApplet.main(new String[] { "--bgcolor=#DFDFDF", "sketch_jul21a" });
  }
}

When you export a sketch, the PDE exports the .java files as well.
