True, False, Error?

@EclipseJavaIDE @java You should stop comparing non-primitives with == to avoid potential bugs. @intellijidea has some nice inspections out of the box to help with that. 😜

@EclipseJavaIDE Error: you have written unclear code that is hard to understand or maintain. Please add code comments.

@EclipseJavaIDE @java False. You are comparing different references

@EclipseJavaIDE @java true : substring with zero index returns the same string object

@EclipseJavaIDE @java Failure in language design. You should not create a language that allows this ambiguity.

@EclipseJavaIDE True,

@EclipseJavaIDE False

@EclipseJavaIDE obviously true

@EclipseJavaIDE I'm pretty sure string literals are automatically interned, so I'll go with "true"

@EclipseJavaIDE intelij idea shows that substring(0) is redundant ;)

@EclipseJavaIDE @java baeldung.com/java-char-sequ…

@EclipseJavaIDE @java True

@EclipseJavaIDE @java It print true based on openjdk source code but it can be true or false based on jre/jvm implementation. Official documentation doesn't note anything about this.

@EclipseJavaIDE @java It’s true. I believe Java compiler gives the same reference type for CharSequence and String.

@EclipseJavaIDE "21"=="21" then true.

@EclipseJavaIDE I'd say true.

@EclipseJavaIDE @java false

@EclipseJavaIDE @java True?

@EclipseJavaIDE @java true

@EclipseJavaIDE @java true

@EclipseJavaIDE @java False

@EclipseJavaIDE True!

@EclipseJavaIDE @java False

@EclipseJavaIDE True

@EclipseJavaIDE @java True

@EclipseJavaIDE true

@EclipseJavaIDE @java False

@EclipseJavaIDE depending on the jdk it can be true or false

@EclipseJavaIDE True. String implements CharSequence. Really you have 2 String instances, and 2 Strings with the same value use the same internal reference.

@EclipseJavaIDE @java true

@EclipseJavaIDE Can someone explain this?

@EclipseJavaIDE True

@EclipseJavaIDE @java True

@EclipseJavaIDE ほるす

@EclipseJavaIDE @java False
