sqlite - byte [] to blob conversion in java using preparedstatement and sqllite -


i trying convert byte [] blob. code follows

        byte [] hashvalue = hashclass.hash256bytes(messagevalue);          //query = "insert message values (?)";         connection = connectionfactory.getconnection();         //blob blob = new javax.sql.rowset.serial.serialblob(hashvalue);         blob blob = new serialblob(hashvalue);         //blob.setbytes(1, hashvalue);          prestatement = (preparedstatement)             connection.preparestatement(query);         prestatement. setblob(1, blob);         rs = prestatement.executequery();

but breaking @ prestatement. setblob(4, blob). have did bit google , tried below code give null @ connection.createblob().

       blob blob = connection.createblob();        blob.setbytes(1, bytes);

try setbytes(); method

    byte [] hashvalue = hashclass.hash256bytes(messagevalue);      //query = "insert message values (?)";     connection = connectionfactory.getconnection();     //blob blob = new javax.sql.rowset.serial.serialblob(hashvalue);     //blob blob = new serialblob(hashvalue);      prestatement = (preparedstatement) connection.preparestatement(query);     prestatement. setbytes(1, hashvalue);     rs = prestatement.executequery();

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
