java - The method printf(String, Object[]) in the type PrintStream is not applicable for the arguments (...)

Question

Why do I get the following compilation error with a simple call to printf? My code:

import java.util.Scanner;

public class TestCodeBankAccInputs
{
    public static void main(String[] args)
    {
        String displayName = "Bank of America Checking";
        int balance = 100;
        System.out.printf("%s has %7.2f", displayName, balance);
    }
}

On compilation I get the following error:

Exception in thread "main" java.lang.Error: Unresolved compilation problem: 
  The method printf(String, Object[]) in the type PrintStream is not applicable for the 
    arguments (String, String, double)
  at TestCodeBankAccInputs.main(TestCodeBankAccInputs.java:9)

What's causing this and how can I fix it?

Version information:

Help->About in Eclipse gives following information:

Eclipse Java EE IDE for Web Developers.

Version: Indigo Release Build id: 20110615-0604

The JDK I installed is JDK1.6.0_27

I have seen this similar issue regarding String.format. Some users have suggested it might be a build issue, but looks like I have updated versions.

Check that the Compiler compliance level is set to at least 1.5 for your project:

Project > Properties > Java Compiler

if Enable project specific settings is not set, use the Configue Workspace Settings... link on that page to check the global Compiler compliance level.
