//create Db Connection
List sqlInsertQueries =

You should make sure that auto commit is false, and use prepared statements. Prepared statements can be used for insert and update.

connection con.setAutoCommit(false);  
PreparedStatement prepStmt = con.prepareStatement("INSERT INTO table (val1,val2) VALUES (?,?)");

for all values:
  prepStmt.setString(1,val1);
  prepStmt.setString(2,val2);
  prepStmt.addBatch();    

stmt.executeBatch(); 
conn.commit();
