engish = Integer.parseInt(txtEng.getText());
tot = maths + science + engish;
avg = tot/3;
if(avg >= 85)
{
grade = "A";
}
else if(avg >= 75)
{
grade = "B";
}
else if(avg >= 65)
{
grade = "C";
}
else if(avg >= 45)
{
grade = "S";
}
else
{
grade = "F";
}
lbltot.setText(String.valueOf(tot));
lblAvg.setText(String.valueOf(avg));
lblGrade.setText(grade);
