Task one:

1. Experimental requirements

Experiment 3 Agile Development and XP Practice ( http://www.cnblogs.com/rocedu/p/4795776.html ), the content of Eclipse is replaced with IDEA

Refer to http://www.cnblogs.com/rocedu/p/6371315.html#SECCODESTANDARD to install the alibaba plugin to solve the specification problem in the code.

Use the tool (Code->Reformate Code) in IDEA to reformat the following code, and then study the Code menu to find a function that makes you feel the best. Submit a screenshot and add your student ID watermark.

public class CodeStandard {
public static void main(String [] args){
StringBuffer buffer = new StringBuffer();
buffer.append('S');
buffer.append("tringBuffer");
System.out.println(buffer.charAt(1));
System.out.println(buffer.capacity());
System.out.println(buffer.indexOf("tring"));
System.out.println("buffer = " + buffer.toString());
if(buffer.capacity()<20)
buffer.append("1234567");
for(int i=0; i<buffer.length();i++)
System.out.println(buffer.charAt(i));
}
}
