Please write this Java Program for me​

Answer 1

Answer:

Explanation:

import java.io.*;

class Student

{

int rollno;

String name;

int number_of_subjects;

int mark[];

Student(int roll,String stud_name,int noofsub)throws IOException

{

rollno=roll;

name=stud_name;

number_of_subjects= noofsub;

getMarks(noofsub);

}

public void getMarks(int nosub ) throws IOException

{

mark=new int[nosub];

BufferedReader br= new BufferedReader (new InputStreamReader(System.in));

for (int i=0; i<nosub;i++)

{

System.out.println(“Enter “+i+”Subject Marks.:=> “);

mark[i]=Integer.parseInt(br.readLine());

System.out.println(“”);

}

}

public void calculateMarks()

{

double percentage=0;

String grade;

int tmarks=0;

for (int i=0;i<mark.length;i++)

{

tmarks+=mark[i];

}

percentage=tmarks/number_of_subjects;

System.out.println(“Roll Number :=> “+rollno);

System.out.println(“Name Of Student is :=> “+name);

System.out.println(“Number Of Subject :=> “+number_of_subjects);

System.out.println(“Percentage Is : “+percentage);

if (percentage>=70)

System.out.println(“Grade Is First Class With Distinction “);

else if(percentage>=60 && percentage<70)

System.out.println(“Grade Is First Class”);

else if(percentage>=50 && percentage<60)

System.out.println(“Grade Is Second Class”);

else if(percentage>=40 && percentage<50)

System.out.println(“Grade Is Pass Class”);

else

System.out.println(“You Are Fail”);

}

}

Maybe it is for advanced level for you, but is a correct program. Try it!
