java - Check if ArrayList<String> contains part of a string

Question

Say I have an ArrayList:

<string1.4>
<string2.4>
<string3.4>

and I wish to return the the first element of the arrayList when I say arrayList.containsSubString('string1'); How could this be done other than iterating through each of the elements of the arrayList and checking if string1 is a substring of that element string?

Answer 1

The only way I can think of is doing something like:

strs.get(strs.indexOf(new Object() {
    @Override
    public boolean equals(Object obj) {
        return obj.toString().contains(s);
    }
}));

Don't know if it is considered good practice though.
