Using resources, you can use method like this:

String customer = "Joe Doe";
String textHello;

textHello = String.format(getString(R.string.hello_customer), customer);

where hello_customer is your string resorce strings.xml.

strings.xml part should look like this:

<string name="hello_customer">Congrats %1$s, you become the potential winner of auction with \"xyz\".</string>

That looks like a mustache template.

See https://github.com/spullara/mustache.java

Typically, in your case:

HashMap<String, Object> scopes = new HashMap<String, Object>();
scopes.put("customer", "xyz");

Writer writer = new OutputStreamWriter(System.out);
MustacheFactory mf = new DefaultMustacheFactory();
Mustache mustache = mf.compile(new StringReader("Congrats {{customer}}, you become the potential winner of auction"), "example");
mustache.execute(writer, scopes);
writer.flush();

like this?

 String string = "Congrats {{customer}}";
 String newValue = string.replace("{{customer}}", "xyz");

  // 'string' remains the same..but 'newValue' has the replacement.
 System.out.println(newValue);

Use the replace method on the String object to do this. Since String is immutable it will return a new object instance with the replaced text. Example:

String myString = "Congrats {{customer}}";
myString = myString.replace("{{customer}}","John");
System.out.println(myString);

Output:

Congrats John

See also the String javadoc for many more useful utility methods.
