Using an object in an if statement... (Android)

Question

I have an object variable Object test = Spinner.getSelectedItem(); -It gets the selected item from the Spinner (called spinner) and names the item 'test'

I want to do an if statement related to that object e.g:

'if (test = "hello") {
//do something
}'

But it appears not to work....

Can someone give me some help? -Do I have to use a different if? or convert the object to string etc.?

Thanks alot...

Answer 1

The statement:

test = "hello"

is an assignment of the string "hello" to the variable test - it doesn't do a comparison.

test == "hello"

is a comparison but still might not work because it compares references. Two different string instances that happen to be both "hello" may not be the same references and therefore the statement may be false.

Try:

"hello".equals( test )

Answer 2

If you want to compare strings, use equals():

if ("hello".equals(test))...

Answer 3

Make test a string and cast the results of getSelectedItem() to a string

string test = (string)Spinner.getSelectedItem();
if (test == "hello") 
{
    //Do something
}

Answer 4

It is also valid in saying test.equals("hello") i don't like the other way it doesn't look right in my coding style.
