Question

I was hoping someone could help me out with a small problem I am having in java. I have a List and an ArrayList that I would like to output to a file with the first element of each, printed next to one another. Here is what I have so far:

List<String> uniqueList = new ArrayList<String>(dupMap.values());
for(String unique:uniqueList){
   out.write(unique + "\r");
}
ArrayList<Integer>subtr=new ArrayList<Integer>();
out.write("The number: " + subtr + "\r");

This results in this output:

A
B
C
D
E
F
The number: [1, 2, 3, 4, 5, 6]

But I would rather it be like this:

A The number: 1
B The number: 2

…etc.

I am not really sure where to start on how to get the output format like that. I tried putting both sets of values into arrays but I just ended up confusing myself… Which is how I ended up here. Any help would be super appreciated.

Answer 1

Simply do this:

String br = System.getProperty("line.separator");
for (int i = 0, n = Math.min(uniqueList.size(), subtr.size()); i < n; i++)
    out.write(uniqueList.get(i) + " The number: " + subtr.get(i) + br);
