help with ' simple if ' program

hi,
i am new to java just started to learn i am now learning decision making logic by using simple if, if-else, and so on.
now i am stuck at a program.

i want display total marks of students
if student belongs to sports category then bonus marks will added in his original marks and then his total marks will be display
and if student is not from sports category then bonus marks will not added only his original marks will display

what will be the syntax of this logic?
i want to use only simple if condition in code
thanks in advance

Post your code with code tags. Tell us what goes wrong, post compiler errors and runtime Exceptions. We'll gladly help, but won't provide ready made code.

You're almost there already; have a look at the translation of the above:

Code:

---

if student belongs to sports category
  display marks+bonus marks
else
  display marks

---

This almost looks like Java ...

kind regards,

Jos

here is my code

package simpleif1;
public class SimpleIf1
{
public static void main(String arg[])
{
int total_marks;
int[] marks = {50, 60, 84, 40};
int[] bonus_marks = {20, 32, 27, 25};
{
if(category == SPORTS)
{
total_marks = marks + bonus_marks;
}
}



}
}

thanks but i dont want to use ' else '

here is my code

package simpleif1;
public class SimpleIf1
{
public static void main(String arg[])
{
int total_marks;
int[] marks = {50, 60, 84, 40};
int[] bonus_marks = {20, 32, 27, 25};
{
if(category == SPORTS)
{
total_marks = marks + bonus_marks;
}
}



}
}

Hi thenamesnake,

Firstly, in your if statement you will need to compare to "SPORTS" not SPORTS.

Secondly, you will need to loop through your arrays adding the content of bonus_marks to marks.
Arrays (The Java™ Tutorials > Learning the Java Language > Language Basics)

Finally, print out the content of marks.

Regards.

Why not?

kind regards,

Jos

maybe this will help

student_marks = marks;
if(Sports)
student_marks = student_marks + bonus_marks; // this will be skipped if there's no Sport

sytem.out.println(student_marks);:D:

it is because, i am doing exercises it strictly having this condition.
that i must do it only with 'simple if'

thanks

Every if-else statement:

Code:

---

if (C)
  S1;
else
  S2;

---

can be converted to 'simple' if statement(s):

Code:

---

boolean elsePart= true;
if (C) {
  S;
  elsePart= false;
}
if (elsePart)
  S2;

kind regards,

Jos
