my first application in java

hello community of steemit, today I want to share my first program in the programming language in java.

actually I am in second year of my career in the university and in this year , we are learning the language of programing "java" , previously we learned the language of programing "C Sharp" and it was my first programming language .

the unique function is calculate the base of the equilateral triangle.

My code

private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
triangulo triangulo = new triangulo();
double val=Double.parseDouble(txt_val.getText());
double val2=Double.parseDouble(txt_base.getText());
double resultado=val+val2;
triangulo.altura=val;
triangulo.base=val2;
txt_resultado.setText(String.valueOf(triangulo.resul()));
}

class triangulo

public class triangulo {
public double base;
public double altura;
public double tot;
public double resul()
{
tot=(base*altura)/2;
return tot;
}
}

I know it is very little but it is a principle and I will strive to learn more and become a great software developer
