I have several enemy sprites I know how to switch their location and speed but not how to change the sprite if anybody could lend me a hand, I have about 12 enemies i wanna use where it says idk how to turn this into a varible
  Enemy(float tempXpos, float tempYpos, float tempXspeed) {
    Enemy_1 = loadImage("Enemy_1.png");
where i can change what I'm loading for an image passing it threw an argument.

1. //Global Varibles
   Enemy myEnemy; //Enemey object Oriented varible
   Enemy myEnemy1; //Second Enemy Object Variable
   //--Global Variable end--
   
   void setup(){ //basic setup for enemy 3 test
     size(1000,680); //skect size
     smooth(); //does something i forgot
     myEnemy = new Enemy(200,400,5);// initializin enemy varible
     myEnemy1 = new Enemy(300,100,4); //initializing second varible of enemy
   }
   
   void draw(){ //our main program
     background(0);
     myEnemy.drawEnemy();
     myEnemy.moveEnemy();
     myEnemy.wallCheck();
     myEnemy1.drawEnemy();
     myEnemy1.moveEnemy();
     myEnemy1.wallCheck();
   }
   class Enemy{
     PImage Enemy_1;
     PImage Enemy_2;
     PImage Enemy_3;
     PImage Enemy_4;
     PImage Enemy_5;
     PImage Enemy_6;
     PImage Enemy_7;
     PImage Enemy_8;
     PImage Enemy_9;
     PImage Enemy_10;
     PImage Enemy_11;
     PImage Enemy_12;
     PImage Enemy_13;
     float enemyX;
     float enemyY;
     float speed;
   
     Enemy(float tempXpos, float tempYpos, float tempXspeed) {
       Enemy_1 = loadImage("Enemy_1.png");
       enemyX = tempXpos;
       enemyY = tempYpos;
       speed = tempXspeed;
     }
     void drawEnemy(){
       image(Enemy_1,enemyX,enemyY);
     }
     void moveEnemy(){
       // Change the x location by speed
       enemyX = enemyX + speed;
     }
     void wallCheck(){
       if ((enemyX > width - 170) || (enemyX < 0)){
     speed = speed * -1;
    }
   }
   }
