What is some JAVA code that will take a sentence and shorten it to 20 characters?

I need to write a java program that will shorten a string to 20 characters but by taking out random characters not just substring at 0,20.





For example: "This would be a sentence that is greater than 20 charcters"





I would like it to randomly make something like this: "TSWLDBESENTHATISGTAN"





So, it uses random letter until the string length is down to 20 characters and then all upper case the string.





Thanks for any help!

String s = "This would be a sentence that is greater than 20 characters";


int len = s.length();


while (len %26gt; 20) {


int i = (int)(Math.random() * len);


s = s.substring(0, i) + s.substring(i+1);


len--;


}


s = s.toUpperCase();
