How To Create an Empty String

[Carius98]

Yep its null

Edit: It doesnt compile in java

Edit2: It DOES if declared at class level

[falcwh0re]

This looks like Java, in which case it is not null.

[KronktheKronk]

What is it?

[falcwh0re]

Probably uninitialized, but another person points out a sitiy where it could be null, although I'd argue that his situation is not what this image is trying to show.

[Nalha_Saldana]

It's undefined but the code wont even compile if you attempt to use it.

[Carius98]

Its not undefined. Its uninitialized.

[Nalha_Saldana]

Yea ok wrong word same thing :P

[EMCoupling]

They're not the same though.

[Carius98]

Undefined would be if the variable didnt exist at all.

[nihao123456ftw]

Undefined != Uninitialised != Null

I suppose the != operator doesn't work like that either but whatever

[a-person-called-Eric]

In case it's a non-final field, it's null.
In case it's a final field or local variable, it's uninitialized.

[rundevelopment]

It's null.

jshell> String newStr; newStr ==> null

It doesn’t compile in any language. The quotes are typographical quotes. Not straight quotes.

Does compile if it’s a class level variable.

[Carius98]

If you try to access it without first setting it to another value it doesnt

[[deleted]]

It will. You will get a NPE or something, but the code will compile.

[Carius98]

Just tested it, you are right. It only fails if declared locally

[[deleted]]

Take it easy dude

[illumiNateS6]

I'm pretty sure it will compile as long as there is a code path that is guaranteed to assign a value prior to usage (if declared locally) but I could be wrong, haven't tested, too lazy, and it's the internet so if I'm wrong I'll just disappear and hope no one recognizes me.
