问题描述：
看java核心技术里一个例子
public class welcome
{
public static void main(String[] args)
{
String[] greeting=new String[3];
greeting[0]="welcome to core java";
greeting[1]="by Gay Horstmann";
greeting[2]="and Gary Cornell";
for(String g:greeting)
System.out.println(g);
}
}
代码无误,执行也正常.可是for(String g:greeting)这一句我看不懂,这是for循环么.
