catch(ArithmeticException e) { System.out.println("Exception: "+ e); a =0;// set a to zero and continue } 当这个版本代替原程序中的版本,程序在标准javaJDK解释器下运行,每一个被零除错误显示下面的消息: 1 Exception: java.lang.ArithmeticException: / by zero 尽管在上下文中没有特殊的值,显示一...

Try catch blockis used forexception handling in Java. The code (or set of statements) that can throw an exception is placed insidetry blockand if the exception is raised, it is handled by the correspondingcatch block. In this guide, we will see various examples to understand how to use t...

Let us begin with an example. Let’s divide two numbers, x, and y. We know that if y is 0, the final value is not defined, therefore this is an exception. An exception in Java is an unexpected condition that can occur during code execution. It is the situation that disrupts the fl...
Exception handling in C++ is a mechanism that allows a program to handle errors or exceptional situations during runtime by using try, catch, and throw statements.
