Qhov thib ob, Cov Ntaub Ntawv Tshiab ua dab tsi hauv Java? Cov ntaub ntawv chav kawm siv tau los tsim ib qho cov ntaub ntawv tshiab hauv Java . Thaum peb pib Cov ntaub ntawv khoom, peb muab cov ntaub ntawv lub npe thiab ces peb tuaj yeem hu rau createNewFile() txoj kev los tsim cov ntaub ntawv tshiab hauv Java . Cov ntaub ntawv createNewFile() txoj kev rov qab yog tias cov ntaub ntawv tshiab yog tsim thiab cuav yog tias ntaub ntawv twb muaj lawm. Txoj kev no kuj cuam tshuam java ua.
Ib yam li ntawd, cov ntaub ntawv ua haujlwm li cas hauv Java?
