我是一名JAVA初学者是自学，经朋友推荐买了本《JAVA编程基础、应用与实例》一个韩国人 徐明浩 写 武传海 翻译成中文讲得很详细。好像和论坛钟所说的那本白色封面的书差不多。封面也是白色的。好了直接上程序
package lianxi;

public class Shere {

  /**
   * @param args
   */
  public static void main(String[] args) {
   String a="国语:90",b="英语:80",c="数学:70";
   int a1=90;
   int a2=80;
   int a3=70;
   int b1=a1+a2+a3;
   int c1=b1/3;
   System.out.println(a+b+c);
   System.out.println("总分："+b1);
   System.out.println("平均分"+c1);
   System.out.println((c1<70)&&(c1>70)?"普通":"优秀");
   /* 80<70 80>70 true :false
   false true
   false 优秀*/
  
  
  }

}
结果应该有个批注：优秀
可小弟不知道该加到哪里，请大虾指教。
在这先谢过了

(c1<70)&&(c1>70) 的结果始终是 false

c1<70 并且 c1>70 ,满足这个条件的c1不存在。

平均成绩小于70 为普通，大于等于70为优秀
System.out.println(c1<70?"普通":"优秀");

(c1<70)&&(c1>70) is an obvious mistake. It is like telling others "I want a c1 less than 70 and meanwhile c1 must be greater than 70"

你的调教判断语句永远为FALSE
因为逻辑与，要两个真才是真。
这种判断应该if~else
语句分开判断的
