Question

Primitive question, but how do I format strings like this:

\"Step {1} of {2}\"

by substituting variables using Java? In C# it\'s

Answer 1

I've wrote my simple method for it :

public class SomeCommons {
    /** Message Format like 'Some String {0} / {1}' with arguments */
    public static String msgFormat(String s, Object... args) {
        return new MessageFormat(s).format(args);
    }
}

so you can use it as:

SomeCommons.msfgFormat("Step {1} of {2}", 1 , "two");

Answer 2

This solution worked for me. I needed to create urls for a REST client dynamically so I created this method, so you just have to pass the restURL like this

/customer/{0}/user/{1}/order

and add as many params as you need:

public String createURL (String restURL, Object ... params) {       
    return new MessageFormat(restURL).format(params);
}

You just have to call this method like this:

createURL("/customer/{0}/user/{1}/order", 123, 321);

The output

"/customer/123/user/321/order"
