How to initialize HashSet with values

Question

How could I initialize a HashSet<Long> with predefined values ?

Example:

    HashSet<Long> hsCtr = 
          new HashSet<Long>(Arrays.asList(6557100201,6557100202,6557100203));

Update: Just force literals into longs by appending "L"

    HashSet<Long> hsCtr = 
          new HashSet<Long>(Arrays.asList(6557100201L,6557100202L,6557100203L));

Thanks

The array values should be long, you need to specify explicitly. Just append l/L to the values inside Arrays.asList(xxxl, xxl, xl);
