Discussion Forum : Flow Control - Finding the output (Q.No. 20)
20.
What will be the output of the program?
int i = 0, j = 5;
tp: for (;;)
{
i++;
for (;;)
{
if(i > --j)
{
break tp;
}
}
System.out.println("i =" + i + ", j = " + j);
Answer: Option
Explanation:
If you examine the code carefully you will notice a missing curly bracket at the end of the code, this would cause the code to fail.

So guys,
I run the code:
if you add the bracket after the general loop YOU HAVE AN UNREACHABLE statement, wich is logic.
Now, if you put the System.out outside the loop, at the end you will have : i =1, j = 0.

It will NOT give error of Unreachable statement, decrements of j will cause i==j eventually and break tp; will break the loop with label tp aka the outer loop.

What is tp doing with break?

If we consider that there are no errors then what could be the result with step by step explanation?

Can anyone explain this source code?
With proper curly brackets, I get the output i=1 and j=0. How?

The last statement would be unreachable because a for (;;) is equivalent of while (true) although it breaks the TP loop but it doesn't break the loop before the last statement.

Even if you put curly braces "}" at the end, It will give you a "compilation error ".
Because the Print Statement,
System.Out.Println("i =" + I + ", j = " + j); will be unreachable.
Because the Print Statement,
System.Out.Println("i =" + I + ", j = " + j); will be unreachable.

How can j = 0, because when break up run it will print the sop statement.
i.e. i = 1, j = 4.
i.e. i = 1, j = 4.

If curly braces of for ended before println then it print i=1 and j=0.

TP represents as label for the loop.
