My first bike was Set(Pulsar 150) Here the output is correct i.e. we wanted the first element and we got in too. But in a program, we need to change this set to an element so that it can be used in the code. So, there are other methods too that will do this job for us. ...
Now we know that the first element in my_list is ‘a’, we can use this information to return the index number at this position as well.In our simplified example, we know that this index number is 0. However, sometimes we might not know the index number that corresponds to a certain...
Here, we use toArray() method to find the first element from LinkedhashSet. Open Compiler import java.util.LinkedHashSet; public class Main { public static void main(String[] args) { LinkedHashSet<String> hm = new LinkedHashSet<>(); hm.add("apple"); hm.add("banana"); hm.add("...
