I wanna the program paused when I press the key and the number currently on the screen is immediately stop and appear on the screen.but for my code when the program paused the number disappeared.Can anyone help with my code please


boolean paused = false;
float x, y;

void setup() {
  size(800, 600);
  background(255);
   textFont(createFont("Georgia", 36));
  textAlign(CENTER, CENTER);
  smooth();
    noStroke();
  x = width / 3;
  y = height / 3;
}
void draw() {

  int randomNum = (int) random(24);
  fill(204, 120);
  rect(0, 0, width, height);
 
  if (!paused){
    fill(144);
  text(randomNum, x, y);}
   

}
void keyPressed() {
 
 if(paused) {
  paused = false;  
 }

 else {
  paused = true;
 }
}

BTW  can anyone help me to do one more step that's every number means a string So that make the output is a string instead of the number and the order of the string should be random

I'm new in processing and for my code I wanna display a picture after the mouse released and the picture can't be same for each time .can anyone help me to change the code.also there is a outofmemory error.
Need help!!!
