Define a class student with the following members
Data Members :
String nm --> to store name of student
int m1,m2.m3 -->to store computer marks of 3 terms
char grad --> to store the grade obtained by student
Member Methods :
void getData() --> to accept name and marks of the three terms of the student from the user
double calAvg() --> to calculate Yearly avg and return it
void calGrade() --> to calculate grade on basis of yearly performance as :
Avg Marks Grade
< 40 D
>=40 & < 60 C
>=60 & < 80 B
>=80 A
void show() --> to display name ,marks of the three terms ,avg marks and the grade obtained by student
Also write a main method to implement above class
import java.util.* ;
public class student
{
private int m1 ,m2 ,m3 ;
private String nm ;
private char grad ;
void getData()
{
Scanner sc = new Scanner(System.in) ;
System.out.println("Enter the name of the student !") ;
nm = sc.nextLine() ;
System.out.println("Enter the marks of the student in Computer in three terms !") ;
m1 = sc.nextInt() ;
m2 = sc.nextInt() ;
m3 = sc.nextInt() ;
if(m1>100 ||m2>100|| m3 >100)
{
System.out.println("Marks obtained is out of 100 ! Please try again ") ;
System.exit(0);
}
}
double calAvg()
{
return (double) (m1+m2+m3)/3 ;
}
void calGrade()
{
double avg = this.calAvg() ;
if(avg< 40)
grad ='D' ;
else if(avg>=40 && avg< 60)
grad = 'C' ;
else if(avg<=60 && avg>60)
grad = 'B' ;
else if(avg>80)
grad = 'A' ;
}
void show()
{
System.out.println("NAME :\t"+nm) ;
System.out.println("MARKS SCORED :") ;
System.out.println("FIRST TERM :\t"+m1) ;
System.out.println("SECOND TERM :\t"+m2) ;
System.out.println("THIRD TERM :\t"+m3) ;
System.out.println("AVERAGE MARKS :\t"+this.calAvg()) ;
System.out.println("GRADE OBTAINED:\t"+grad) ;
}
public static void main(String[] args)
{
student student1 = new student() ;
student1.getData();
student1.calGrade();
student1.show();
}
}
