Demonstrates URL encoding and decoding. Chilkat2 Java

import com.chilkatsoft.chilkat2.StringBuilder;

public class ChilkatExample {

    public static void main(String[] args) {
        // To URL encoding a string:
        String s = "Why a > b?";

        StringBuilder sb = new StringBuilder();
        sb.append(s);

        // URL encode the string.
        sb.encode("url", "utf-8");

        // Show the URL encoded string:
        String sEncoded = sb.getAsString();
        System.out.println(sEncoded);

        // The result is:  Why%20a%20%3E%20b%3F

        // If you prefer "+" instead of "%20" for SPACE chars:
        int numReplaced = sb.replace("%20", "+");
        System.out.println(sb.getAsString());

        // Output is:   Why+a+%3E+b%3F

        // To decode:
        sb.decode("url", "utf-8");
        System.out.println(sb.getAsString());

        // Result is: Why a > b?
