[ Java 常見問題 ] Named placeholders in string formatting

Source From Here
Question
In Python, when formatting string, I can fill placeholders by name rather than by position, like that:

view plaincopy to clipboardprint?

1. print "There's an incorrect value '%(value)s' in column # %(column)d" % \  
2.   { 'value': x, 'column': y }  

I wonder if that is possible in Java (hopefully, without external libraries)? Thanks in advance.

How-To
StrSubstitutor of jakarta commons lang is a light weight way of doing this provided your values are already formatted correctly. Sample code as below:

view plaincopy to clipboardprint?

1. Map values = new HashMap();  
2. values.put("value", 1);  
3. values.put("column", 2);  
4. StrSubstitutor sub = new StrSubstitutor(values, "%(", ")");  
5. printf("%s\n", sub.replace("There's an incorrect value '%(value)' in column # %(column)"))  

Output:

There's an incorrect value '1' in column # 2
