Thread: cannoot find symbol

Hi.
What's wrong with:

	public void showResults(Info[] queue,int k)
	{
 
		String results = "";
		for(int i =0;i<queue.length;++i)
		if(nameChecked)
		  results += queue[i].name;
		if(archChecked)
		    results += queue[i].arch;
		if(versionChecked)
		    results += queue[i].version; 
	}

I cannot understand compiler hints

EDIT:
sysinfoHooshi.java:162: cannot find symbol
symbol : variable i
location: class sysinfoHooshi
results += queue[i].arch;
^

The error message is pretty clear, the variable "i" is never defined when you try to use it. Just look at your code very closely, and you will see that i is not visible everywhere where it is used.
This would be your code with proper brackets:

	public void showResults(Info[] queue,int k)
	{
 
		String results = "";
		for(int i =0;i<queue.length;++i) {
			if(nameChecked)
			  results += queue[i].name;
		}
		if(archChecked)
		    results += queue[i].arch;
		if(versionChecked)
		    results += queue[i].version; 
	}

Eh...I haven't defined it?Look inside for-loop...I have. haven't I? I have.....seemingly, unless it goes out of scope

Look at my correction of your code, you might notice that the line:

results += queue[i].arch;

tries to use a variable i which has not been defined in the same scope.
