Feem ntau, txhua qhov kev thov nyeem tau ua los ntawm Tus Nyeem Ntawv ua rau muaj qhov sib txuas nyeem ntawv thov kom ua los ntawm tus cwj pwm los yog byte kwj.

Hauv qhov no, BufferedReader yog dab tsi hauv Java?

BufferedReader yog ib chav kawm hauv Java uas nyeem cov ntawv los ntawm tus cwj pwm-input kwj, buffering cov cim thiaj li muab kev nyeem ntawv zoo ntawm cov cim, kab thiab arrays. Qhov loj tsis tuaj yeem raug teev tseg. Yog tsis yog, lub default size, uas yog predefined, tej zaum yuav siv tau.

Tsis tas li ntawd, vim li cas peb thiaj siv BufferedReader hauv Java? Cov BufferedReader yog siv los muab qhov buffering rau tus nyeem ntawv cov khoom thaum nyeem cov ntaub ntawv los ntawm input kwj. Cov BufferedReader chav kawm nce qhov kev ua tau zoo ntawm qhov kev pab cuam. Koj qhov kev zov me nyuam khiav nrawm vim qhov tsis txaus thiab nyeem tau zoo ua los ntawm cov BufferedReader chav kawm.
