hola, disculpa por alguna razon la funcion append no existe y no me funciona, no me deja concatenar

[@Choriwonca]

The append() method is available in the StringBuilder class, but not in the JTextArea class. To concatenate strings in JTextArea, you can use the setText() method.
Here is a modified version of your Semestre() method that uses setText() to concatenate the semester number to the text area:
java
public void Semestre(){
// Check which radio button is selected
if(Radio1.isSelected()){
// Set the text of the text area to "Semestre: N°1"
TxtArea1.setText("
Semestre: " + "N°1");
} else if(Radio2.isSelected()){
// Set the text of the text area to "Semestre: N°2"
TxtArea1.setText("
Semestre: " + "N°2");
} else if(Radio3.isSelected()){
// Set the text of the text area to "Semestre: N°3"
TxtArea1.setText("
Semestre: " + "N°3");
} else if(Radio4.isSelected()){
// Set the text of the text area to "Semestre: N°4"
TxtArea1.setText("
Semestre: " + "N°4");
} else if(Radio5.isSelected()){
// Set the text of the text area to "Semestre: N°5"
TxtArea1.setText("
Semestre: " + "N°5");
} else if(Radio6.isSelected()){
// Set the text of the text area to "Semestre: N°6"
TxtArea1.setText("
Semestre: " + "N°6");
}
}
This modified method should work as expected.
