Question

要把
class TV 
        {  /* 定义成员变量 */ 
            String color="彩色电视机";  
            String  pattern ="25英寸";  //规格 
            double price=1000.0; 
            String  MadePlace="China"; 
            int  AllChannels=50; //频道总数 
            int  NowChannel; //正在收看的频道 
            boolean  key ;      //开关的状态             /* 定义方法 */ 
            //Open the TV 
            public boolean OpenTV() 
            { 
                key=true; 
                return key; 
            } 
            //Close the TV 
            public boolean CloseTV() 
            { 
                key=false; 
                return key; 
            }     
            //Change the channel 
            public void ChangeChannel(int channel) 
            { 
                NowChannel=channel; 
            } 
            //Get the channel which is running 
            public int GetChannelRunNow() 
            { 
                return NowChannel; 
            } 
            //Reduce the price 价格打折
            public double ReducePrice(double percent) 
            { 
                return price=price*(1-percent); 
            } 
            public String TVMessage() 
            { 
                String TVMeg; 
                TVMeg="Color:\t\t"+color 
                          +"\nPattern:\t\t"+pattern 
                          +"\nMadePlace:\t\t"+MadePlace 
                          +"AllChannels:\t\t"+Integer.toString(AllChannels); 
                return TVMeg; 
            }     
        }//TV类定义结束 
放到另外一个文件TV.class中，然后编译。

Answer 1

不用放在另一个文件里,把 class TV的定义移出 class TVset
像这样:package TVset;
import java.io.*; 
public class TVset 
{ 
    public static void main(String args[]) 
    { 
        TV tv1=new TV(); 
        System.out.println(tv1.TVMessage()); 
    }//main函数结束 
        //类TV的定义      
}

            { 
                NowChannel=channel; 
            } 
            //Get the channel which is running 
            public int GetChannelRunNow() 
            { 
                return NowChannel;

                String TVMeg; 
                TVMeg="Color:\t\t"+color

能够运行.
