Given that: TestABC.java is located at: test/x/y/z/TestABC.java testdata.txt is located at: resources/x/y/z/TestABC/testdata.txt classpath includes resources folder We are trying to read the testdata.txt from TestABC.java. We need a location independent way to point to these files. Therefore, we would like to use getResource() method of a Class or ClassLoader. Here are the correct ways: 1: this.getClass().getClassLoader().getResource("x/y/z/TestABC/testdata.txt"); 2: this.getClass().getResource("/x/y/z/TestABC/testdata.txt")); 3: this.getClass().getResource("TestABC/testdata.txt")); Explanation: 1: works because ClassLoader takes the path as it is (no manipulation) and search in the classpath folders. In this case, it will go to the resources folder and it will find the testdata.txt file in the given path. 2: works because Class.getResource takes the "absolute" path, removes its starting / and t
Here is a short explanation of when these predicates are true (From http://www.wellho.net/mouth/985_Equality-in-Ruby-eql-and-equal-.html) The == comparison checks whether two values are equal eql? checks if two values are equal and of the same type equal? checks if two things are one and the same object. How do I remember which is which ... The longer the operator, the more restrictive the test it performs Let's understand the differences with some examples. Each "abc" below is a different object. Therefore, equal? is false. irb(main):065:0> "abc".object_id => 24173330 irb(main):066:0> "abc".object_id => 24165760 irb(main):067:0> "abc" == "abc" => true irb(main):068:0> "abc".eql? "abc" => true irb(main):069:0> "abc".equal? "abc" => false As you might expect, there is a single instance of 1. Therefore, all comparisons are true. irb(main):094:0> 1.class =>
