以下实例演示了使用 System 类的 System.err.println() 来展示异常的处理方法：
ExceptionDemo.java 文件
class ExceptionDemo
{
public static void main(String[] args) {
try {
throw new Exception("My Exception");
} catch (Exception e) {
System.err.println("Caught Exception");
System.err.println("getMessage():" + e.getMessage());
System.err.println("getLocalizedMessage():" + e.getLocalizedMessage());
System.err.println("toString():" + e);
System.err.println("printStackTrace():");
e.printStackTrace();
}
}
}
以上代码运行输出结果为：
Caught Exception getMessage():My Exception getLocalizedMessage():My Exception toString():java.lang.Exception: My Exception printStackTrace(): java.lang.Exception: My Exception at ExceptionDemo.main(ExceptionDemo.java:5)
