Yog li ntawd, puas yog qhov phem uas muaj nested sim ntes?

Tsis xav tau ua zes los yog ntau yam sim - ntes hauv tib txoj kev. Qee zaum a nested Sim - ntes yog yam tsis muaj kev zam. Piv txwv li thaum qhov yuam kev rov qab code nws tus kheej tuaj yeem pov thiab kev zam . Tab sis txhawm rau txhim kho qhov kev nyeem tau ntawm cov cai koj tuaj yeem ib txwm rho tawm cov ua zes thaiv rau hauv ib txoj kev ntawm nws tus kheej.

Qhov thib ob, dab tsi yog nested sim thaiv hauv Java? Nested sim blocks hauv Exception Handling in Java . Java 8 Object Oriented ProgrammingProgramming.

Txhawm rau daws lawv, peb xav tau nested sim blocks.

Xav txog qhov no, peb puas tuaj yeem sau ntau sim blocks hauv Java?

Ntau sim blocks : Koj tsis tuaj yeem muaj ntau sim blocks nrog ib tug catch thaiv . Txhua sim thaiv yuav tsum tau ua raws li kev ntes los yog thaum kawg. Tseem yog koj sim kom muaj ib tug ntes thaiv rau ntau sim blocks lub sij hawm ua yuam kev yog generated.

Muaj pes tsawg sim ntes blocks tuaj yeem muaj?

Nws muaj ib sim block thiab peb ntes blocks. Tsuas yog ib qho kev ntes block yuav raug tua ib zaug, nws nyob ntawm lub logic hauv sim block. Hauv kuv qhov sim thaiv, cov cai muaj peb hom kev zam.
