4、RuntimeException异常主要包括以下四种异常(其实还有很多其他异常,这里不一一列出):空指针异常(NullPointerException)、数组下标越界异常(ArrayIndexoutOfBoundsException)、类型转换异常(ClassCastException)、算术异常(ArithmeticException)。RuntimeException异常会由java虚拟机自动抛出并自动捕获(就算我们没写异常捕获语句运...
ClassNotFoundException一般是通过反射获取某个类时会出现,比如Class.forName("类的全限定名称") NoClassDefFoundError一般是通过new的方式创建某个类的时候,并且在编译期class类存在,但是运行期等到加载类的时候class不存在(比如丢了或者手动删除了) 3)都是由于类不存在导致的,为啥又要区分呢 我觉得,是因为出现的场景...
ClassNotFoundException意思就是找不到指定的class。 遇到的场景: 1、调用class的forName方法时,找不到指定的类 2、ClassLoader 中的 findSystemClass() 方法时,找不到指定的类 3、ClassLoader 中的 loadClass() 方法时,找不到指定的类 packagetest;publicclasstest {publicstaticvoidmain(String[] args) {try{...
总结一下,简单来说,NoClassDefFoundError和ClassNotFoundException都是由于在CLASSPATH下找不到对应的类而引起的,通常是缺少对应的jar包,不过,JVM认为: (1)当应用运行时没有找到对应的引用,则会抛出java.lang.NoClassDefFoundError; (2)当你在代码中显式加载类(使用Class.forName())时没有找到对应的类,则会抛出java...
ClassNotFoundException异常通常发生在以下情况下: 类路径错误:当我们在编译或运行Java程序时,如果指定的类文件不存在于类路径中,就会抛出ClassNotFoundException异常。这可能是由于文件路径错误、类文件未正确放置在类路径中等原因引起的。 类名错误:如果我们在编译或运行Java程序时,指定了不存在的类名,也会导致ClassNot...
