Problems with converting a String to a float

Processing Electronics (Arduino, etc.)

Processing code:

import processing.serial.*;

Serial myPort;
int lf = 10;
float temp =0.1;
String s =null



void setup() {
myPort = new Serial(this, "COM5", 9600);
myPort.clear();
s = myPort.readStringUntil(lf);
}

void draw() {
while (myPort.available() > 0) {
s = myPort.readStringUntil(lf);

if (s != null) {
String[] list = split(s, ",");
 
String sen1 = list[0];

float temp = float(list[1]);


delay(600);
    }
   } 
  }
