Selam arkadaşlar, java ile basit bir emailsender yapmıştım paylaşmak istedim. Email hesabınızdan giriş yaptığınızda bu program üzerinden maillerinizi gönderebilirsiniz. Program statik çalışıyor, yani ne cmd’den nede herhangi bir arayüz aracılığı ile değişkenlere değer atanmıyor. Fakat bunu isterseniz çok basit bir şekilde yapabilirsiniz. Umarım işinize yarar.
