Hi Kc
In order to println(something), it must first compute the "something",
then to print it. When computing "person1.getName() = " + ... +
person1.computeTotalWelth() + ..., it calls the method
computeTotalWelth() who just prints 3000. Once the computation is don,
it prints the rest. So 30000 is printed in advance.
Hope it helps

Hi,
I notice the example code produce this output:
30000
person1.getName() = Sang Shin, person1.computeTotalWealth() = 30000,
person1.measureIntelligence() = 50
30000
personinterface1.getName() = Sang Shin,
personinterface1.computeTotalWealth() = 30000
looking at the code, I can't figure out why 30000 is printer as first
line:
System.out.println("person1.getName() = " + person1.getName()
+ "," +
" person1.computeTotalWealth() = " +
person1.computeTotalWealth() + "," +
" person1.measureIntelligence() = " +
person1.measureIntelligence(person1.getName()));
System.out.println("personinterface1.getName() = " +
personinterface1.getName() + "," +
" personinterface1.computeTotalWealth() = " +
personinterface1.computeTotalWealth());
which i believe the 30000 come from the println() statement in
computeTotalWealth(), just why it appear as first?
public int computeTotalWealth(){
System.out.println((cashSaving + retirementFund));;
return (cashSaving + retirementFund);
}
Regards
KC
