I have an ArrayList full of strings arrays that I built like this:
String[] words = new String[tokens.length];
I have three arrays like above in my ArrayList:
surroundingWords.add(words);
surroundingWords.add(words1);
surroundingWords.add(words2);
etc
Now if I want to print out the elements in the String arrays within surroundingWords... I can't. The closest I can get to displaying the contents of the String[] arrays is their addresses:
[Ljava.lang.String;@1888759
[Ljava.lang.String;@6e1408
[Ljava.lang.String;@e53108
I've tried a lot of different versions of what seems to be the same thing, the last try was:
for (int i = 0; i < surroudingWords.size(); i++) {
String[] strings = surroundingWords.get(i);
for (int j = 0; j < strings.length; j++) {
System.out.print(strings[j] + " ");
}
System.out.println();
}
I can't get past this because of incompatible types:
found : java.lang.Object
required: java.lang.String[]
String[] strings = surroundingWords.get(i);
^
Help!
I've already tried the solutions here: Print and access List
Try something like this
public class Snippet {
public static void main(String[] args) {
List<String[]> lst = new ArrayList<String[]>();
lst.add(new String[] {"a", "b", "c"});
lst.add(new String[] {"1", "2", "3"});
lst.add(new String[] {"#", "@", "!"});
for (String[] arr : lst) {
System.out.println(Arrays.toString(arr));
}
}
}
