Difference between methods to getResourceAsStream

Question

有人可以告诉我MyClass.class.getClassLoader().getResourceAsStream("TestFile.txt")和MyClass.class.getResourceAsStream("TestFile.txt")什么区别

Answer 1

They are (more or less) equivalent. Class#getResourceAsStream() will get the ClassLoader internally and delegate the getResourceAsStream call to it.

Thanks to VGR's comments . It's important to note that Class#getResourceAsStream(String) first delegates to Class#getResource(String) which, if it doesn't start with a / , transforms the String argument passed by pre-pending the package name of the corresponding class with a / replacing each . .
