我怎么能故意创建一个简单的运行时错误？

Question

I'm testing a batch script, to check that it's handling any errors when a compiled jar is run.

What's the simplest snippet of a code I can add to my java to cause a runtime error?

Answer 1

您可以简单地抛出RuntimeException ：

throw new RuntimeException("Test runtime exception");

Answer 2

for (int i=0; i<1; i++){
  int x = 10/i; // Arithmetic exception
}

Answer 3

在for循环之前声明x然后键入x=10/i;
