Regarding targeting and such

So I'm making a game where I want a turret object to be able to choose between a random set of targets. The targets are several arrays of similar objects (for example, 5 scout craft, 2 light fighters, 3 heavy cruisers). Once a target is chosen, the turret then fires its weapon at the target at its firing rate. Any suggestion for the best way to go about doing this?
- class Turret {
float xPos, yPos;
float accuracy, hull, dr, shield;
int firingRate, fire;
float xSize, ySize;
boolean isClicked, noTarget;
String name;
// turrets can display, but cannot move
void display() {
//rectMode(CENTER);
fill(255);
rect(xPos, yPos, xSize, ySize);
strokeWeight(3);
stroke(255);
noFill();
ellipse(xPos+xSize/2, yPos+ySize/2, xSize*2, ySize*2);
strokeWeight(1);
stroke(0);
}
void displayHUD() {
if (isClicked==true && hud.isOn==true) {
textFont(smallText);
fill(255, 100, 100);
text(hull, 80, 18);
text(accuracy*100+"%", 100, 36);
text(firingRate/30+"/second", 120, 54);
text(name, width/2, 36);
fill(0);
textFont(font);
}
}
// turrets can take damage
void takeDamage(int dmg) {
// Turrets are immobile targets. However, they can be upgraded with shields and DR, later.
// 1d20+accuracy rating vs. 1d20+defense rating
hull-=dmg;
}
// turrets can target enemy ships
void targetShip() {
if (numSS!=0) {
int temp=int(random(numSS));
for (int i=0; i<numSS; i++) {
if (i==temp && noTarget==true) {
ss[i].setTarget();
noTarget=false;
}
else {
break;
}
}
}
}
// if focus is on this cannon, its attributes will be displayed as text
void checkFocus() {
if (mouseX>=xPos && mouseX <= xSize+xPos) {
if (mouseY<=yPos+ySize && mouseY>=yPos) {
if (isClicked==false && hud.isObjectFocused==false) {
isClicked=true;
hud.isObjectFocused=true;
}
else if (isClicked==true) {
isClicked=false;
hud.isObjectFocused=false;
}
}
}
}
}
class LaserTurret extends Turret {

l = new Laser(xPos, yPos, ss[i].xPos, ss[i].yPos);
l.display();
ss[i].takeDamage(accuracy, l.dmg);
fire=0;
} else {
}
}
}
else if (fire<firingRate) {
fire++;
}
}
}
- class Ship {
float xPos, yPos; // Every ship has a position on the 2D world plane. In addition, each ship has a height and width.
int xSize, ySize;
float hull, defense, xVector, yVector, dmgbonus, accuracy; // Every ship has a hull value, defense value, and speed values. The dmgbonus value is added in some form to the ship's weapons
int firingRate;
