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));
}
}
我找到了官方API(http://www.antlr.org/api/Java/index.html),但我仍然不知道如何解决它。
