Write a program to declare and initialize some variables of int, string and double , accept their values and print the result according the requirement.
public class Variables
{
public static void main()
{
//declaration of variables
String st_nm;
int std;
double total;
int roll_no;
int math;
int geo;
int comp;
int bio;
int hin;
//initialization of variables with the values
st_nm="Dhvani";
std=12;
roll_no=1201;
math=98;
geo=100;
comp=99;
bio=97;
hin=90;
total=math+geo+comp+bio+hin;
System.out.println("The total marks of”+ st_nm+” is "+total);
double average=total/5;
System.out.println("The average of ”+ st_nm +” is "+average);
double per=total*100/500;
System.out.println("The percentage of”+ st_nm +” is "+per);
}
} Output:
The total marks of Dhvani is 484.0
The average of Dhvani is 96.8
The percentage of Dhvani is 96.8
