Random generator does not work it always shows 0

Question

import java.util.Random;

public class PouAbilites {
    protected int Health;

    public int getHealth(){
        return this.Health;
    }

    public void setHealth(final int Health){
        final Random random  = new Random();

        final int randomInt = random.nextInt(100)+1;
        this.Health=randomInt;  
    }
    PouAbilites(){
       this.Eletero=getEletero();
    }
    public void onscreen(){
        System.out.println("Health: "+ this.Health);
    }
}

The main function is included in an other class:

package KotelezoProgram;

public class Main {
    public static void main(final String[] args) {
        final PouAbilites Pou = new PouAbilites();
        Pou.onscreen();
    }
}

Answer 1

call setHealth() in between

PouAbilites Pou = new PouAbilites();
Pou.onscreen();

calls

Calling onscreen() before setHealth() will return 0 because this.Health is just initialized in the Pou object to zero.
