What is the output?

[Varuna Seneviratna]

   
 
class OutPut
{
public static void main(String[] args)
{
OutPut o=new OutPut();
 
o.go();
 

}
void go()
{
int y=7;
 
for(int x=1; x<8; x++)
{
y++;
if(x>4)
{
System.out.print(++y + " " );
}
if(y>14)
{
System.out.println(" X = " + x);
break;
 
}
}
}
 

}
 

How can the output of the above program be 13 15 X =6
From where is the 13 coming from

It comes from inside this code:

if(x>4)
{
System.out.print(++y + " " );
}

Why do you think it shouldn't be there?

[Varuna Seneviratna]

 
System.out.print(++y + " " );
 
   

From the above statement the output is 15 and a space

    
System.out.println(" X = " + x);
 

From the right above it should be
X = 6;


In the final screen it should be

15 X = 6


I can't figure out from where the 13 is coming from

Right I just got it the 13 is sent to the screen and X=6 is sent next in the next iteration, with 2 added to 13, that is 15.So finally 13, then in the next iteration 15 X=6 and the final screen looks 13 15 X=6


Am I right?

Work out what happens when x == 5.

I see you have worked that out; it might be easier to understand if you count forwards!
