We Are Going To Discuss About ‘Optional.get()’ without ‘isPresent()’ check. So lets Start this Java Article.

‘Optional.get()’ without ‘isPresent()’ check

  1. 'Optional.get()' without 'isPresent()' check

    ...findFirst().orElse(null);
    Returns the value if present, otherwise returns null. The documentation says that the passed parameter may be null (what is forbidden for orElseGet and orElseThrow).

  2. 'Optional.get()' without 'isPresent()' check

    ...findFirst().orElse(null);
    Returns the value if present, otherwise returns null. The documentation says that the passed parameter may be null (what is forbidden for orElseGet and orElseThrow).

Solution 3

my solution was to check it this way

if(item.isPresent()){
  item.get().setId("1q2w3e4r5t6y")
}

Solution 4

Optional was created so code could after all these decades, finally start avoiding null.

Remove the .get(), return the Optional itself and make the calling code deal with it appropriately (just as it would have to do in the case you’d be returning null).
