Thread: Presumably simple fix sets/maps

The linkedlist's line values.

I want to compare the objects(ints aka line numbers) in the linked list that are stored in the value location on the TreeMap.

wordmap is line 2. the values for each entry are above their respective entries.
Running.
[cat=[2], mouse=[3, 3], phone=[4, 5], string=[1]]
[2]
ID: cat Lines: 2 Occurance: 1
[3, 3]
ID: mouse Lines: 3, 3 Occurance: 2
[4, 5]
ID: phone Lines: 4, 5 Occurance: 2
[1]
ID: string Lines: 1 Occurance: 1

What is your suggestion? I must be missing the point. I do not see how my printout is different from yours except for the concatenation of "wordMap=" and "pE entry=".

So you are saying what needs to be inserted into the linked list needs to be a string including the line number instead of an integer? ...Or are we just talking about output for debugging purposes?

Output:
wordMap=[cat=[2], mouse=[3, 3], phone=[4, 5], string=[1]]
pE entry=[2]
ID: [cat] Lines: 2 Occurance: [1]
pE entry=[3, 3]
ID: [mouse] Lines: 3, 3 Occurance: [2]
pE entry=[4, 5]
ID: [phone] Lines: 4, 5 Occurance: [2]
pE entry=[1]
ID: [string] Lines: 1 Occurance: [1]

Unfortunately not. It is still printing out the second 3 for mouse.

I have tried various forms of that

		//local occurance variable
		int occurance = 1;
		String check = "";
		//System.out.println("pE entry=" + entry.getValue().toString());
 
		//print the word and the line numbers as well as test for duplicate line integers on the same key
		Iterator itr = ((LinkedList) entry.getValue()).iterator();
		System.out.print("ID: [" + entry.getKey() + "]   Lines: " + itr.next());
		while(itr.hasNext()){
			occurance++;
			//check = itr.toString();
			if(itr.equals(itr.next())){ //what i assumed would work
			System.out.println("blah");
			}
			else{
			System.out.print(", " + itr.next()); //no such element exception
			}	
		}
		//prints occurance from incremented occurance variable
		System.out.print("  " + " Occurance: [" + occurance + "]");
		System.out.println();
	}

I have also tried declaring a string variable to compare the itr.toString() and itr.next().toString() but after further testing, different line numbers result in the same string, this made no sense to me. I just added a .toString() method at the end of my line number printer.
I tried making an integer variable to store the previous value but had a type mismatch error converting from object to int. this part confused me the most as I know I am pulling a value from inside an object.

But to answer your question, they are next to each other in the list. I don't know EXACTLY what separates them but when I print out the map entries or the entry values they are both listed in the format "[#,#]"

There is currently no point in my code that saves an item for checking. How would I save the value itr.next() prints? I cannot make some integer variable and just assign it to equal itr.next() as my IDE gives me a cannot convert from object to int error.
