Those names such as "[I" and "[java.lang.String" are the internal names of "int[]" and "String[]". Paragraph 4.3 of the Java Virtual Machine Specification explains how these names work. For example, "[" means it's an array and "I" means "int".

The classes for arrays are things that are built-in into the compiler. You will not find a Java source file or *.class file anywhere for those classes.

I broke up the long line in your code. Please don't put very long lines inside code tags (I suggest you give the UseCodeTags page another read).
