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).
For this I tried,
Package pkg = Package.getPackage("com.abc"); // This gives me null object in pkg
But when I do,
Package pkg = A.class.getPackage(); // It works fine
Can anyone notify, Why Package.getPackage("package-name") is not working ?
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.
