Let us assume that you want to charge a metal ball positively.So for that you have to take a negatively charged object and place it near the metal ball, in metal ball all the postive charge came near the end where the negative charge is, and all the negative negative charge of metal ball shifts on the farther end due to repusion , now take another conductor and place it in contact with the metal ball so that all the negetive charge flows from that end to the new conductor, now seperate both. Congratulation You got positive charge in sphere .
