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?

You can simply throw a RuntimeException:
throw new RuntimeException("Test runtime exception");

How do I insert this without getting a
unreachable statement compilation error?dwjohnston
The way I did it was by just replacing everything that was in the main block with your snippet. Works for what I'm doing.

put an
if (true) statement before itfor (int i=0; i<1; i++){
int x = 10/i; // Arithmetic exception
}

Seems like a rather convoluted way to do something so simple.

Put
if(true) instead of loop, if you like. Just some another way of doing wht OP wants :)Bimalesh Jha
Ideally any such code is hardwaired and difficult to remove without recompiling later. Just for testing a jar file, I would pass an argument through cmd line and induce an exception conditionally while testing.
declare x before for loop
then type x=10/i;
