ArrayIndexOutOfBoundsException: This occurs when trying to access an array element outside its bounds. IllegalArgumentException: This occurs when a method receives an invalid argument.

数组初始化后元素默认值为`null`,`test[index]`(即`test[1]`)的值为`null`,因此`foo`被赋值为`null`。 3. **选项C**(异常):错误。`index=1`在数组合法索引范围内(0~2),不会触发`ArrayIndexOutOfBoundsException`;将`null`赋值给字符串变量是允许的,也不会触发空指针异常。 4. **选项D**(无法...
在`try`块中,`throw new ArrayIndexOutOfBoundsException()`会立即抛出异常,其后的语句`int a = 1/0`由于位于`throw`之后,成为无法到达的代码(Unreachable code)。Java编译器会检测到这一问题,并抛出编译错误。因此程序无法运行,直接输出结果为**错误(选项D)**。各选项分析:- **A(rrrvvv)**:错误。未发生...

异常用Exception类表示,包括ClassNotFoundException类、IoException类等等。 运行时异常用RuntimeException类表示,描述的是代码的错误。如ArithmeticException类、NullPointerException类、IndexOutOfBoundsException类、IllegalArgumentException类等等。 其中运行时异常和系统错误及其它们的子类都称为免检异常,所有其他的异常都称为...

在`try`块中,首先执行`int a = 1/0`,会立即抛出`ArithmeticException`。此时程序跳转至对应的`catch(ArithmeticException e)`块,输出"rrr"。此时,`try`块中后续的代码(如`b[4]=4`)**不会继续执行**,因此不会触发`ArrayIndexOutOfBoundsException`。无论是否发生异常,`finally`块始终执行,因此会继续输出"...
As the other guys have already mentioned, ArrayIndexOutOfBoundsException is an Exception that occurs when you are trying to access an array using an incorrect index. This could be caused by a very simple bug in programming logic. StackOverflowError is something more low-level. It has nothing ...
This method will throw ArrayIndexOutOfBoundsException if you pass an index whose value is very small (negative number) or very large (larger than number of elements contained by the Vector currently). If you try to compile ListOfNumbers class, the compiler prints the error message about an ...
