average and displays the stream accordingly:

Average Marks

Stream

80% and above

Computer Science

60% or more but less than 80%

Bio-Science

40% or more but less than 60%

Commerce
​

Answer 1

Answer:

Answer:

import java.util.Scanner;

public class Average {

public static void main(String[] args) {

Float num1, num2, num3, avg;

Scanner sc = new Scanner(System.in);

System.out.println("Enter physics marks : ");

num1 = sc.nextFloat();

System.out.println("Enter chemistry marks : ");

num2 = sc.nextFloat() ;

System.out.println("Enter biology marks : ");

num3 = sc.nextFloat();

sc.close();

avg = (num1 + num2 + num3)/3;

int val =(int)avg;

System.out.println("Average of these subjects: "+val);

Answer 2

Answer:

public class Grades

{

public static void main (String args[])

{

int p,b,c;

flot avg=0;

String name,gr="";

System.out.println("Enter Name");

name=in.nextInt();

System.out.println("Enter Marks In Physics,Chemistry and Biology");

p=n.nextInt();

b=in.nextInt();

c=in.nextInt();

avg=(p+b+c)/3;

if (avg>=80)

gr="Computer Science";

if (avg<=60&&avg>80)

gr="Bio-Science";

if (avg<=40&&avg>60)

gr="Commerce";

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

System.out.println("Avg Marks:"+avg);

System.out.println("Grade:"+gvr);

}

}
