You can use pointer arithmetic with negative values, hence an array index can be negative. Exemple of valid array access with a negative index: voidf(void) { intx; int*p; inttab[3] = {1,2,3}; p = &tab[2]; // points tothe 3rd element ...

Is this your case what you want save in that array, or values of that variables to what that pointers pointed? Saturday, March 5, 2016 5:50 PM I'm still think about some safe conversion of that pointers and wrote little code that make some conversions using void pointer and return...

常见形式为(XxxError)。...运行时异常 RuntimeException及其子类如:NullPointerException,ArrayIndexOutOfBoundsException等都属于运行时异常。...特点: 方法抛出运行时异常,无需定义throws声明,调用者也无需处理。运行时期异常发生后,需要程序员进行代码修改。 ...当父类被覆盖的方法没有异常声明时,子类覆盖方法无法...
空指针检查:在进行类型转换或调用toArray方法之前,确保ArrayList不为null,以避免NullPointerException。 通过遵循这些步骤和注意事项,你可以有效地避免cannot be cast to [Ljava.lang.String;这类错误,并确保你的代码更加健壮和可靠。
