Hi all,
converting some materials for undergraduates, i have uncover a weird bug.
This snippet of code doesn't work in jshell
(jshell --enable-preview).
I get
jshell> record Rectangle(int width, int height) {
...> double diagonal() {
...> return Math.hypot(with, height);
...> }
...> }
...> var rectangle2 = new Rectangle(4, 3);
...> System.out.println(rectangle2.diagonal());
| Error:
| cannot find symbol
| symbol: class Rectangle
| var rectangle2 = new Rectangle(4, 3);
| ^-------^
So the class/record Rectangle doesn't seem to be registered ?
Changing it to
record Rectangle(int width, int height) {
double diagonal() {
return 5;
}
}
var rectangle2 = new Rectangle(4, 3);
System.out.println(rectangle2.diagonal());
do work ??
