This tutorial will teach how to make a Student Grade Calculation in Java. Input the studentname and avg marks to calcuate the grade
if the average is > 85 – A
if the average is > 75 – B
if the average is > 65 – C
if the average is > 55 – S
if the average is < 45 – F
Paste the inside the Calc Button
double maths,science,engish,tot,avg;
String grade;
maths = Integer.parseInt(txtMaths.getText());
science = Integer.parseInt(txtSci.getText());
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);
I have attached the video tutorial below it will help you to do this step by step.
