I’m working on a Java Swing application where I need to store the output of if-else conditions in an array and then call this stored array in a different JFrame.
here is the sample code that im working

private void submitButtonActionPerformed(java.awt.event.ActionEvent evt)                                             
       ArrayList<Gradeprac> studList = Gradeprac.getStudentList();
    DefaultTableModel model = (DefaultTableModel) tblStudents.getModel();
    int rowCount = model.getRowCount();

    for (int i = 0, row = 0; i < studList.size(); i++) 
        if (studList.get(i).section.equals(cmbSections.getSelectedItem().toString())) 
            Object value = model.getValueAt(row, 2);

            if (value == null || ((String) value).isEmpty()) 
                value = "NE";
                model.setValueAt(value, row, 2);
 
            String grade = convertToGrade(value);

            System.out.println("Percentage: " + value + "% - Grade: " + grade);

            row++;
  
private String convertToGrade(Object value) 
    try 
        double percentage = Double.parseDouble(value.toString());
        int percentageInt = (int) percentage;

        if (percentageInt < 100 && percentageInt >= 96.5) 
            return "1.00";
         else if (percentageInt < 97 && percentageInt >= 92.5) 
            return "1.25";
         else if (percentageInt < 93 && percentageInt >= 88.5) 
            return "1.50";
         else if (percentageInt < 89 && percentageInt >= 84.5) 
            return "1.75";
         else if (percentageInt < 85 && percentageInt >= 81.5) 
            return "2.00";
         else if (percentageInt < 82 && percentageInt >= 78.5) 
            return "2.25";
         else if (percentageInt < 79 && percentageInt >= 75.5) 
            return "2.50";
         else if (percentageInt < 76 && percentageInt >= 72.5) 
            return "2.75";
         else if (percentageInt < 73 && percentageInt >= 69.5) 
            return "3.00";
         else if (percentageInt < 70 && percentageInt >= 0) 
            return "5.00";
        else 
            return "INC";
        
     catch (NumberFormatException e) 
        return "NE";
         

thank you
