Question

I want Suggestion that which one is better based on performance?

List<byte[]>

or

HashMap<String,byte[]>

For me key doesnt matter. I’m going to store only list size of 2 in object. First one represent one constant and another represent another constant.

Also is there any better way of solution other than two also please suggest me.

Thanks in Advance.

Answer 1

Why not create a pojo class to hold the values ?

Class ConstantHolder {

  private final byte[] constant1;
  private final byte[] constant2;

  public Holder(byte[] constant1, byte[] constant2) {
    this.constant1 = constant1;
    this.constant2 = constant2;
  }

  getters for constants;

}
