Cannot understand the output

[Aparna Misri]

Hi All,

This question is from Wizlabs 1.4 . In this I am not able to understand what will be the output.Question is as follows :

What will happen when you attempt to compile/run the following code?

public class MyClass
{
public static void main(String args[])
{
int total=0;

for(int i=0,j=10;total>30;++i,--j)
{
System.out.println("i="+i+":j="+j);
total+=(i+j);
}

System.out.println("Total"+total);
}
}



A. Produce a runtime error.
B. Produce a compile time error
c. Print out "Total 0"
D. Generate the following as output:
i=0 : j=10
i=1 : j=9
i=2 : j=8
Total30

I think c is the correct answer. The pitfall is here

int total=0;
for(int i=0,j=10;total>30;++i,--j)

The condition will be false for the very first time so the loop will never get executed...

Oh yes...you are right Ankit....
Now I got it...
Thanks a lot

Ankit,
If I replace "total>30" with "total<30" in the same question what will be the output.
