How to change each word in a string to upper case?

Question

I am trying to find a why in Spring, Java to upper case each word in a string?

Can StringUtils do it?

Answer 1

You can use the toUpperCase() method in String.

String x = "lowercasestring";
x = x.toUpperCase();
System.out.println(x);

The output will be LOWERCASESTRING

EDIT :

You can use the WordUtils class of the Apache Commons-lang. The capitalize method will convert the first letter of a space separated words. The following code demonstrates it:

String x = "a lower case string";
x = WordUtils.capitalize(x);
System.out.println(x);

The output will be A Lower Case String. You can also refer the docs for the WordUtils class here.
