Which one needs an object?
Short answer. throw, written as throw new Exception(...)
Where is throws written?
In the method heading, followed by exception class names.
throw vs throws
| Point | throw | throws |
|---|---|---|
| Job | raises one | warns caller |
| Where | method body | heading |
| Then | new object | class names |
Remember
| throw new Exception(...) |
| void f() throws IOException |
One letter apart, but a different job. See the difference. Throw raises one exception now. It sits in the method body. It needs a new object; throws lists class names. Remember. Throw new raises it. Throws in the heading passes it on.
