r (tsheb thauj mus los) yog qhov zoo li yog tias koj paub txog cov phau ntawv qub qub: Nws txav lub "carriage" (lub yob daim ntawv yog pub los ntawm) rov qab mus rau qhov pib ntawm kab.
Ib yam li ntawd, tib neeg nug, dab tsi yog tus cwj pwm?
r yog lub tsheb thauj mus los (CR) tus cwj pwm , tus cwj pwm code 13. Lawv ua dab tsi txawv ntawm qhov system mus rau qhov system.

Qhov thib ob, kev siv cov tsheb thauj mus los hauv Java yog dab tsi? a tsheb rov qab ntawm lub tshuab luam ntawv tau txav txoj haujlwm luam tawm mus rau qhov pib ntawm kab tam sim no tab sis nyob ntawm tib kab. Ib txoj kab tshiab tau hloov txoj hauj lwm luam tawm mus rau kab tshiab tab sis tsis hloov txoj hauj lwm kem. Qee lub tshuab luam ntawv tuaj yeem luam tawm sab laug-txoj cai thiab sab xis-sab laug.
Ua raws li qhov no, qhov sib txawv ntawm thiab yog dab tsi?
Lawv yog cov cim txawv. r yog carriage rov, thiab yog kab pub. Hauv cov tshuab luam ntawv "laus", r xa lub taub hau luam ntawv rov qab mus rau qhov pib ntawm kab, thiab nce cov ntawv los ntawm ib kab. Hauv C# thiab Java, piv txwv li, ib txwm txhais tau tias Unicode U + 000A, uas txhais tau tias yog kab noj.
