Yuav ua li cas koj siv tus sib piv hauv Java?
Siv Comparator
- Tsim ib chav kawm uas siv Comparator (thiab yog li qhov sib piv () txoj kev uas ua haujlwm yav dhau los ua los ntawm kev sib pivTo()).
- Ua ib qho piv txwv ntawm Comparator class.
- Hu rau tus txheej txheem overloaded sort(), muab nws ob lub npe thiab cov piv txwv ntawm chav kawm uas siv Comparator.
