Receiving two values over serial port using servos So I have a java program that picks up the mouses x and y coords on the display and I would like to send those to my arduino and then move my two servos to those locations (I have two servos ontop of each other, one for x and one for y).

The java (processing) code i have is below

void draw(){  //same as loop in arduino
  background(52, 152, 219); // background color of window (r, g, b) or (0 to 255)
  //lets give title to our window
  fill(0, 255, 0);               //text color (r, g, b)
  textFont(font);
  text("Ripple Effect Maker", 80, 30);  // ("text", x coordinate, y coordinat)
  ellipse(mouseX, mouseY, 33, 33);
  int x = mouseX;
  int y = mouseY;
  port.write(x+":"+y);
  println(x+":"+y);
  //println("y="+y);
  delay(100);
}


I don't have much arduino code because I can't seem to find a way to split the data into two seperate variables and then move the servos to their corresponding variables.

Thanks for the help!
Your problem is that you aren't providing anything to split the data on. You just send the X and y coordinates with a : between X and y. There's nothing between the y and the next X.

By changing the line

port.write(x+":"+y);


To

port.write(x+":"+y+"\n");


You then get the linefeed character to split your data on.
