variables - How do I find Constructors and needed inputs for JAVA class? -

-

I am trying to see that the constructor and input execution needed to start the Java object properly.

I do not use plain text. Java file only compiled class.

I have tried the code below but when I run the order of any example. Outside or I get a bunch of exceptions. Exception can be thrown because nothing was found. 

  import java.lang.reflect.Constructor; Import java.lang.reflect.Type; Static import java.lang.System.out; Public Square ConstructorSift {Public Stable Zero Main (String ... Args) {{class

I'm not a Java programmer.

You can use commands in the Java tool set.

c++ - Cassandra datastax cpp driver - avoiding unnecessary copies -

-
I use the following method to create my insert statement for Cassandra (using datastax cpp driver) : ssStmt1 & lt; & Lt; "Insert some table (...) value (....)" string sStatement1 = ssStmt1.str (); Castestring cass1 = cass_string_init (sStatement1.c_str ()); CassStatement * pStmt1 = cass_statement_new (cass1, 0); I have also tried the following: CassString cass1 = cass_string_init ("Enter some table (id, date, c) value (? ,?,?); "); CassStatement * pStmt1 = cass_statement_new (cass1, 3); Cass_statement_bind_uuid (pStmt1, 0, uuidKey); Cass_statement_bind_int64 (PSTMT1, 1, timestamp); Cass_statement_bind_string (pStmt1, 2, sSomething); The first pattern works with mixed keys, the second is not. The key has a timestamp and a UUID. Timestamp is one of two errors in the field (based on the used bond statement). If bound in this way: cass_statement_bind_int64_by_name (pStmt1, "date", timestamp); I get the following error: Inva...
