Package.getPackage in java returning null

Question

I have some classes A, B, C in package com.abc

I have a Class Main in package com.pqr

Now I want to create a package object of the previous pacakge (abc).

Answer 1

Package.getPackage will only return a non-null value if the current ClassLoader is already aware of the package. Try this:

Package pkg = Package.getPackage("com.abc");
System.out.println(pkg);
Class<A> a = A.class;
pkg = Package.getPackage("com.abc");
System.out.println(pkg);

The first System.out will print 'null', the second will print the package name as the ClassLoader has then loaded a class from it.
