Write a program to define a class student with four data members such as name, roll no., sub1, and sub2. Define appropriate methods to initialize and display the values of data members. Also, calculate total Marks and percentage scored by the student.
import java.lang.*; import java.io.*; class student { String name; int roll_no; int sub1,sub2; int total; float per; void getdata() throws IOException { BufferedReader br = new BufferedReader(new InputStreamReader(System.in)); System.out.println ("Enter Name of Student"); name = br.readLine(); System.out.println ("Enter Roll No. of Student"); roll_no = Integer.parseInt(br.readLine()); System.out.println ("Enter marks out of 100 of 1st subject"); sub1 = Integer.parseInt(br.readLine()); System.out.println ("Enter marks out of 100 of 2nd subject"); sub2 = Integer.parseInt(br.readLine()); } void show() { total=sub1+sub2; per=(total*100)/200; System.out.println ("Roll No. = "+roll_no); System.out.println ("Name = "+name); System.out.println ("Marks of 1st Subject = "+sub1); System.out.println ("Marks of 2nd Subject = "+sub2); System.out.println ("Total Marks = "+total); System.out.println ("Percentage = "+per+"%"); } } class q2Student { public static void main(String args[]) throws IOException { student s=new student(); s.getdata(); s.show(); } }
