Answer 1

Answer:

I think the answer will be this see the explanation

Explanation:

import java.util.Scanner;

public class Student

{

private String name;

private int age;

private int m1;

private int m2;

private int m3;

private int maximum;

private double average;

public Student(String n, int a, int s1,

int s2, int s3) {

name = n;

age = a;

m1 = s1;

m2 = s2;

m3 = s3;

}

public Student() {

name = "";

age = 0;

m1 = 0;

m2 = 0;

m3 = 0;

maximum = 0;

average = 0;

}

public void accept() {

Scanner in = new Scanner(System.in);

System.out.print("Enter name: ");

name = in.nextLine();

System.out.print("Enter age: ");

age = in.nextInt();

System.out.print("Enter Subject 1 Marks: ");

m1 = in.nextInt();

System.out.print("Enter Subject 2 Marks: ");

m2 = in.nextInt();

System.out.print("Enter Subject 3 Marks: ");

m3 = in.nextInt();

}

public void compute() {

if (m1 > m2 && m1 > m3)

maximum = m1;

else if (m2 > m1 && m2 > m3)

maximum = m2;

else

maximum = m3;

average = (m1 + m2 + m3) / 3.0;

}

public void display() {

System.out.println("Name: " + name);

System.out.println("Age: " + age);

System.out.println("Subject 1 Marks: " + m1);

System.out.println("Subject 2 Marks: " + m2);

System.out.println("Subject 3 Marks: " + m3);

System.out.println("Maximum Marks: " + maximum);

System.out.println("Average Marks: " + average);

}

public static void main(String args[]) {

Student obj = new Student();

obj.accept();

obj.compute();

obj.display();

}

}
