You need to place all statements after the declarations in a code block, e.g. method rather than the class block. Logically it probably makes sense to place all statements in the code block but the non-declarative statements need to be enclosed within the new block
private void processFile() { data.put("1", new Object[]{"ID","NAME", "LASTNAME"}); // <--Syntax error ...//snip } catch (Exception e) { e.printStackTrace(); } }
