Implement Preprocessor #include with StringBuilder

Demonstrates how to implement #include with a Chilkat StringBuilder. Java

import com.chilkatsoft.*;

public class ChilkatExample {

  static {
    try {
        System.loadLibrary("chilkat");
    } catch (UnsatisfiedLinkError e) {
      System.err.println("Native code library failed to load.\n" + e);
      System.exit(1);
    }
  }

  public static void main(String argv[])
  {
    //  First build a string that has a preprocessor include
    CkStringBuilder sbSrc = new CkStringBuilder();
    sbSrc.Append("1\r\n2\r\n3\r\n");
    sbSrc.Append("#include <qa_data/txt/helloWorld.txt>\r\n");
    sbSrc.Append("4\r\n5\r\n");

    System.out.println(sbSrc.getAsString());

    //  sbSrc contains:
    //  	1
    //  	2
    //  	3
    //  	#include <qa_data/txt/helloWorld.txt>
    //  	4
    //  	5

    //  The qa_data/txt/helloWorld.txt file contains "Hello World!"

    String filePath = sbSrc.getAfterBetween("#include","<",">");
    if (sbSrc.get_LastMethodSuccess() != true) {
        System.out.println("No #include's found.");
        return;
        }

    System.out.println("filePath: " + filePath);

    //  Load the contents of the filePath
    CkStringBuilder sbIncludeFile = new CkStringBuilder();
    sbIncludeFile.LoadFile(filePath,"utf-8");

    //  Replace the first occurrence of #include <...> line with the contents of the include file.
    sbSrc.ReplaceAllBetween("#include",">",sbIncludeFile.getAsString(),true);

    System.out.println(sbSrc.getAsString());

    //  sbSrce now contains:
    //  	1
    //  	2
    //  	3
    //  	Hello World!
    //  	4
    //  	5
  }
