What is the operator for "Less than or Equal to" in Java?

I am familiar with Actionscript programming, and I often used the "<=" (less than or equal to) or ">=" (greater than or equal to) operators.

However in Eclipse, I have been unable to use such operators. Here's my situation. Defined variable:

final EditText UserNumber = (EditText) findViewById(R.id.editText1);

And here's the use:

if (UserNumber <= 10){ }

I'm sure this is a very easy/quick fix but I have been unable to locate what should be used in this situation.

And this is the error I'm getting:

The operator <= is undefined for the argument type(s) EditText, int

As a solution, use this instead 

Integer.parseInt(UserNumber.getText().toString());

In your case, this works fine, 

 if((Integer.parseInt(UserNumber.getText().toString()) )<=10)
            {
               //Do what you want 
            }

Dangerous bend! You cannot use <= etc to compare Java objects. You need to use a compareTo method if it is implemented. This goes especially for strings.

You will first need to get the text from the edit text view, then if it is a Integer get the value from the string.

        Integer.parseInt(UserNumber.getText().toString());

As mentioned above.

As the error clearly states, you can't compare an EditText instance to a number.

You probably want to get the EditText's value.
