La prima parte di questo esercizio consiste nel dividere il genoma del corona virus in parti da 10 lettere, con il seguente codice che crea anche una grafica con bottone e jTextArea:
package coronavirus;

jToggleButton1.setText("genoma del corona virus");
jToggleButton1.addActionListener(new java.awt.event.ActionListener() {
public void actionPerformed(java.awt.event.ActionEvent evt) {
jToggleButton1ActionPerformed(evt);
}
});
jTextArea1.setColumns(20);
jTextArea1.setRows(5);
