import  org.antlr.v4.runtime.*;
import  org.antlr.v4.runtime.tree.*;

public class Test{
public static void main(String[] args) throws Exception{

    ANTLRInputStream input = new ANTLRInputStream(System.in);

    ArrayInitLexer lexer = new ArrayInitLexer(input);

    CommonTokenStream tokens = new CommonTokenStream(lexer);

    ArrayInitParser parser = new ArrayInitParser(tokens);

    ParseTree tree = parser.init();
    System.out.println(tree.toStringTree(parser));


}
}

I have found the official API (http://www.antlr.org/api/Java/index.html) , but I still don't know how to solve it.

Their official ANTLR site recommends using the CharsStreams class as from version 4.7 ANTRLInputStream is deprecated.

  • Thanks. But how should I modify my code? – Daxer Jun 05 '18 at 03:25

    @Daxer as with all deprecated method/codes, it is not mandatory to change, however, in newer versions of the library, they might be removed. So it's always a good idea to change to the newer functionality. – Bart Kiers Jun 05 '18 at 07:25
  • @Daniel Doctor Thank you for your enthusiasm. I have solved my problem :) – Daxer Jun 05 '18 at 12:12
