Thinking in Java 学习笔记1

昨天学习Thinking in Java，学会打印字符值，代码如下：

public class Exercise1
{

   private static int  i;
   private static char c;

   public static void main(String[] args)
   {
      System.out.println("i = " + i);

      System.out.println("c = " + +c); //在要打印的字符前加“+”号，即可打印出这个字符的字符值

      String s = "This is a test";
      for (int i = 0; i < s.length(); i++)
      {
         System.out.println(+s.charAt(i)); 
      }
   }
}
