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...
3.java中的异常类分为三种类型:系统错误、异常和运行时异常。 系统错误是有JVM抛出的,用Error类表示。 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、Illega...
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...

The Java compiler is smart enough to convert the method reference to String’slength()method into aFunction(a functional interface) whoseapplymethod takes a String and returns an Integer. For example: 1for(Strings:args)out.println(leng2.apply(s)); ...
stack trace includes information about program subroutines and can be used to debug or troubleshoot and is often used to create log files. These exceptions could be custom (defined by the user) or built-in. Examples includeRuntimeException,NullPointerException, andArrayIndexOutofBoundsException. ...
We have several WARN and ERROR messages found in our logfile, what is the purpose or it? Here some examples Raw WARN [org.infinispan.rest.Http20RequestHandler] (REST-ServerWorker-5-6) ISPN012006: Uncaught exception in the pipeline: java.lang.StringIndexOutOfBoundsException: String index out ...
In this tutorial, we will discuss how to set java.library.path. We will explain its definition, and how can be used by Java applications. The Java Virtual Machine (JVM) uses the java.library.path property in order to locate native libraries. This property is part of the system environment...
