Part III: Experimental summaryThrough this week's study, learned some basic Java content, recognized that its language is really very similar to C language, after learning C language is easy to understand some of the content, in the process of doing experiments on

array class . The experiment was more complicated than the first experiment . But with the last Test of eclipse, the understanding of the relatively smooth. The first three experiments mainly on the basic Java grammar, the common mistake is that double quotation marks should be used in the English state, as well as many different from the C language grammar knowledge, through the experiment, these errors have a more profound understanding.
