Here's a link which explains the two.
Data are plain facts. When data are processed, organized, structured or presented in a given context so as to make them useful, they are called Information.
It is not enough to have data (such as statistics on the economy). Data in themselves are fairly useless. But when these data are interpreted and processed to determine its true meaning, they become useful and can be called Information. Data is the computer's language. Information is our translation of this language.
Both data and information are types of knowledge or something used to attain knowledge. Though used interchangeably, there are many differences between the meanings of these two words.
Data refers to the lowest abstract or a raw input which when processed or arranged makes meaningful output. It is the group or chunks which represent quantitative and qualitative attributes pertaining to variables. Information is usually the processed outcome of data. More specifically speaking, it is derived from data. Information is a concept and can be used in many domains.
Information can be a mental stimulus, perception, representation, knowledge, or even an instruction. The examples of data can be facts, analysis, or statistics. In computer terms, symbols, characters, images, or numbers are data. These are the inputs for the system to give a meaningful interpretation. In other words, data in a meaningful form is information.
However out of context I don't see how this has anything to do with the Java Language itself. As opposed to some obtuse tidbit of information that the author is trying to convey.
