ArrayList<String> x = new ArrayList<String>();
for(int i = 0; i < x.size(); i++)
{
ArrayList<String> x.get(i) = new ArrayList<String>();
}
Both ArrayLists should be declared globally
The x ArrayList values are: server,buser,paer cook, runner, etc.
The first ArrayList value should be second ArrayList name(variable)
It is not possible to set variable names dynamically in Java. If you still want to give some description to arrays of string you can create a Map for instance. i.e.
ArrayList<String> x = new ArrayList<String>();
Map<String, ArrayList<String>> vars = new HashMap()<>;
for(int i = 0; i<x.size(); i++)
{
vars.put(x.get(i),new ArrayList<String>());
}
...
vars.get("server").add("Some Server info");
First typeof x isn't ArrayList<String>, it is ArrayList<ArrayList> because x's element is ArrayList
Second, you can't set element of ArrayList with ArrayList.get, you should use ArrayList.set
ArrayList<ArrayList> x = new ArrayList<>();
//todo something with size of `x` (if not x.size() = 0)
for (int i = 0; i < x.size(); i++) {
x.set(i, new ArrayList<String>());
}
Try like this, You cannot create variable name dynamically.
public static void main(String[] args) {
List<String> x = new ArrayList<>(Arrays.asList("server", "buser", "paer cook", "runner"));
Map<String, ArrayList<String>> map = new HashMap<>();
// if java version is 8
x.forEach(eachElem -> {
map.put(eachElem, new ArrayList<>());
});
// if java version is < 8
// for(String eachElement : x ){
// map.put(eachElement, new ArrayList<>());
// }
}
selenium?ArrayList<String> x.get(i) = new ArrayList<String>();doesn't compile...
