if statement inside the print statement?

How can I write an if statement inside the print statement?

public boolean checkEmpty()
{
    if(array.isEmpty)
    {
        Sytem.out.println("The List is empty");
    }
    else
    {
        System.out.println("The list has: " +  if(array.size() > 1)) {"Items"} + else {"item"} );
    }
}
Solution

  • You can't write an if statement inside an expression like that.

    However, you can use Java's ternary operator ?: (scroll down about half way in the linked page) to embed a conditional expression:

    System.out.println("The list has: " +  ((array.size() > 1) ? "items" : "item"));

    The format is:

    booleanCondition ? valueIfTrue : valueIfFalse
