Here is a simple way:


public class StringStuff {

public static void main(String[] args) {

String input = null;
if (args.length > 0){
input = args[0];
} else {
input = "How now brown cow?";
}
StringBuffer sb = new StringBuffer(input);
sb.reverse();
String output = sb.toString();
System.out.println(output);

}

}

I think you need at least 2 string functions - .length() and .charAt():

public class Cl {
public static void main(String[] args) {
String before = "A Sample String", after = "";
for (int i = 0; i < before.length(); ++i) after += before.charAt(i);
}
}
