Order of execution:
- System.out.println(text.getClass()) // prints "class java.lang.String" with an enter
- retrieve text.getClass() // returns a Class object for String
- append that Class object with " unknown "; the Class object is turned into a String using its toString method, and the result is "class java.lang.String unknown "
- call new Test().test()
- inside that method, print out getClass() // prints "class Test" without an enter
- inside that method, return ""
- take the return value and append it to the previous String. It is know "class java.lang.String unknown "
- print out that String // prints "class java.lang.String unknown " with an enter
Since one of the print outs misses an enter (print is called, not println) the "class Test" and "class java.lang.String unknown " are printed directly after each other.
