C# “is” operator alternative in Java [duplicate]

Question

This question already has answers here:

Check if an object belongs to a class in Java [duplicate] (6 answers)

Closed 7 years ago.

in C# when I want to know if an object is an instance of a particular type or not, I can use "is" operator:

String foo = "hi :)"
if (foo is String) ...

how can I do it in java? (I know I can use try statement, any other way?)

Answer 1

You'd use instanceof - that's the equivalent of is in C#. Note that there's no equivalent of as.

See the JLS section 15.20.2 for more details of instanceof, but it's basically the same as is:

// Note: no point in using instanceof if foo is declared to be String!
Object foo = "hello";
if (foo instanceof String)
{
    ...
}

Answer 2

instanceof is the java equivalent to the C# is operator.

Answer 3

Java equivalent:

String foo = "hi :)"
if (foo instanceof String)

Answer 4

Try something like this:-

String foo = "hi :)"
if (foo instanceof String)
{
 ......
}

Answer 5

In java you can use "instanceof" instead of "is"

String foo = "hi :)"
if (foo instanceof String) 

Answer 6

if (foo instanceof String)

I believe is what you're looking for
