Strings.format("htpp?value1={VALUE_2}&value2=${VALUE_1}", new HashMap<String, Object>() {
            {
                put("{VALUE_1}", 123);
                put("{VALUE_2}", "321");
            }
        });

should return "htpp?value1=321,value2=123"

Why does none of these not suit you?

@Test
public void testFormat() {
    int value1 = 123, value2 = 321;
    assertEquals("http?value1=321,value2=123", String.format("http?value1=%2$s,value2=%1$s", value1, value2));
    assertEquals("http?value1=321,value2=123", MessageFormat.format("http?value1={1},value2={0}", value1, value2));
}

Do you absolutely need named value or is it just needed for inversion?

The idea is to set key name but not key number in Strings.format()
Because order 1,3,2,5,7 may change and may be mistake if many numbers.

With names key it's look better.

Like in Python http://docs.python.org/library/string.html#format-examples
Python sample:
'Coordinates: {latitude}, {longitude}'.format(latitude='37.24N', longitude='-115.81W')

Java sample: (maybe you can improve)

Strings.format("'Coordinates: {latitude}, {longitude}'", new HashMap<String, Object>() {
            {
                put("longitude", "-115.81W");
                put("latitude", "37.24N");

        }
    });

Okay, so that's really a variable interpolation[1] you want. It is used inside Maven and Ant, and Apache Configuration supports it, but doesn't exactly show an isolated way to use it as it is rather integrated. It's indeed not really easy to find such implementation.

So basically what you are looking for is what StrSubstitutor in Apache Commons / Lang does:

At this time, we don't plan to add any templating tools to Guava.
