The import statement in this listing is somehow misunderstood.
import java.math.BigInteger;
class Fact {
static BigInteger fact(BigInteger n) {
if (n.equals.BigInteger.ZERO) return BigInteger.ONE;
return fact(n.subtract(BigInteger.ONE)).multiply(n);
}
}
It generates the errors (and more):
11 errors found:
File: D:\Desktop\Fact.dj2 [line: 1]
Error: The class java.math.BigInteger is not in the right package. Perhaps you meant to package it?
File: D:\Desktop\Fact.dj2 [line: 1]
Error: java.math.BigInteger is not public, and thus cannot be seen here
Changing the import statement to
import java.math.*;
works.
