ArrayList issue

[drogba123]

hi,

a1.add("every");
a1.add("bobs");
a1.add("three");
a2.add("ev");
a2.add("ob");

for (String bigram1 : a2) {
for (String words : a1) {
if (words.contains(bigram1)) {
if(test.containsKey(bigram1)){
test.get(bigram1).add(words);
}
else {
test.put(bigram1, new ArrayList<String>(a1));
}
}
}
}
System.out.println(test);

but it does not make any comparison

{ev=[every, bobs, three], ob=[every, bobs, three]}

displayed all values. what is wrong in this codes?thanks.

We haven't the slightest clue what the variable test represents. This does look wrong though:

test.put(bigram1, new ArrayList<String>(a1));

db

edit And use code tags, not quote tags, to post code.

hi db,

thank for the reply

HashMap<String, ArrayList<String>> test = new HashMap<String, ArrayList<String>>();

ArrayList <String> a1 = new ArrayList<String>();
ArrayList <String> a2 = new ArrayList<String>();

test represent hashmap

and a1 and a2 represent 2 arraylists

So, what does the code line I quoted do? What does it put into the Map?

What are the contents of new ArrayList<String>(a1)
