InputMismatchException是Java中的一个异常类,它表示输入不匹配的异常情况。当使用Scanner类读取输入时,如果输入的数据类型与预期的数据类型不匹配,就会抛出InputMismatchException异常。 InputMismatchException通常发生在使用Scanner类的nextXXX()方法读取不正确类型的输入时,比如使用nextIn
InputMismatchException是 Java 中的一个运行时异常,通常在使用Scanner类从输入源(如文件)读取数据时发生。当Scanner期望某种类型的数据(例如整数),但实际读取到的数据类型不匹配时,就会抛出这个异常。 相关优势 类型安全:通过抛出异常,Java 确保了程序在处理输入时的类型安全性。
In this tutorial, we will learn about the Java InputStream class and its methods with the help of an example. The InputStream class of the java.io package is an abstract superclass that represents an input stream of bytes.
