arraylist value into string value

Question

I have a arraylist containing values like [ addidas 5 100 , nike 10 300 , woodland 4 800] so if i print am gettinh result as

value1 :: adidas
value2 :: 5
value3 :: 100

result has to be like

value1 :: adidas,nike,woodland
value2 :: 5,10,4
value3 :: 100,300,800

ArrayList<String> array;

int j = 0;

String[] parts;
String value1;
String value2;
String value3;

for (j = 0; j <= array.size(); j++) {

    parts = array.split(" ");

    value1 = parts[0];
    value2 = parts[1];
    value3 = parts[2];

    System.out.println("value1::" + value1);
    System.out.println("value2::" + value2);
    System.out.println("value3::" + value3);

}

parts = array.split(" "); what are you trying to achieve here? — Prateek

Where is the code where you're actually putting stuff into the array? — Dawood ibn Kareem

_{Since this looks like homework there will be no code here.}
There is one error in your code and few in logic.

split can be invoked on String so first you should get that string from your array list
you said that you want to print all elements of the same category (value1, value2, value3) in same line but your loop prints one value of each category in each iteration. To solve this problem you should store split values in separated lists and print them after loop ends.
