using class and methods

Hi Friend,

Try the following code:

import java.util.*;

public class Student{
int rollNo;
double sub1;
double sub2;
double sub3;
double sub4;
double sub5;
double totalMarks;
public Student(int rollNo,double sub1,double sub2,double sub3,double sub4,double sub5,double totalMarks){
this.rollNo=rollNo;
this.sub1=sub1;
this.sub2=sub2;
this.sub3=sub3;
this.sub4=sub4;
this.sub5=sub5;
this.totalMarks=totalMarks;
}
public int getRollNo(){
return rollNo;
}
public double getSub1(){
return sub1;
}

public double getSub2(){
return sub2;
}

public double getSub3(){
return sub3;
}

public double getSub4(){
return sub4;
}

public double getSub5(){
return sub5;
}

public double getTotalMarks(){
return totalMarks;
}

public static void main(String[]args){
Scanner input=new Scanner(System.in);
double max1=0,max2=0,max3=0,max4=0,max5=0,max=0;
int no=0;
double s1=0,s2=0,s3=0,s4=0,s5=0,tm=0;
ArrayList<Student> list = new ArrayList<Student>();
for (int i=1; i<=2; i++) {
System.out.print("Enter Roll No: ");
no=input.nextInt();
System.out.print("Enter marks of Maths: ");
s1=input.nextDouble();
System.out.print("Enter marks of Science: ");
s2=input.nextDouble();
System.out.print("Enter marks of Hindi: ");
s3=input.nextDouble();
System.out.print("Enter marks of English: ");
s4=input.nextDouble();
System.out.print("Enter marks of Social Studies: ");
s5=input.nextDouble();
tm=s1+s2+s3+s4+s5;
list.add(new Student(no,s1,s2,s3,s4,s5,tm));
System.out.println();

if (s1 > max1) {
max1 = s1;
}
if (s2 > max2) {
max2 = s2;
}
if (s3 > max3) {
max3 = s3;
}
if (s4 > max4) {
max4 = s4;
}
if (s5 > max5) {
max5 = s5;
}
if (tm > max) {
max = tm;
}
}

continue..

System.out.println("*********Roll No and Total Marks*********");
System.out.println("Roll No Total Marks");
for (Student s : list){
System.out.println(s.getSub1()+" "+s.getSub2());
}
System.out.println();
System.out.println("*********Highest marks in each subject with RollNO*********");
for (Student s : list){
if(s.getSub1()==max1){
System.out.println("Roll No " +s.getRollNo()+" get highest marks in Subject 1 i.e "+max1);
}
}
for (Student s : list){
if(s.getSub2()==max2){
System.out.println("Roll No " +s.getRollNo()+" get highest marks in Subject 2 i.e "+max2);
}
}
System.out.println();
for (Student s : list){
if(s.getSub3()==max3){
System.out.println("Roll No " +s.getRollNo()+" get highest marks in Subject 3 i.e "+max3);
}
}

for (Student s : list){
if(s.getSub4()==max4){
System.out.println("Roll No " +s.getRollNo()+" get highest marks in Subject 4 i.e "+max4);
}
}
for (Student s : list){
if(s.getSub5()==max5){
System.out.println("Roll No " +s.getRollNo()+" get highest marks in Subject 5 i.e "+max5);
}
}
System.out.println();
System.out.println("*********Student Obtained Highest Marks*********");
for (Student s : list){
if(s.getTotalMarks()==max){
System.out.println("Roll No " +s.getRollNo()+" get highest marks");
}
}

}
}

Thanks

Hi Friend,

We have created a loop for only 2 students, you can place 10 in place of 2 so that program will display the results of 10 students.

Thanks
