Answer 1

package tmpoint;




public class TMPoint {


String phoneNo;


String custName;


String dateinstall;


double installFee;
TMPoint(){
    
}
public TMPoint(String p, String c, String d, double i){
    phoneNo = p;
    custName = c;
    dateinstall = d;
    installFee = i;
}


void setinstallFee(double i){
     installFee = i;
}
void setphoneNo(String i){
     phoneNo = i;
}
void setDateinstall(String i){
     dateinstall = i;
}
void setCustName (String i){
     custName = i;
}


String getPhone(){
         return phoneNo;
     }
String getCustName(){
         return custName;
     }
String getDateinstall(){
         return dateinstall;
     }
double getinstallFee(){
         return installFee;
     }
    public static void main(String[] args) {
        // TODO code application logic here
    }
    
}


class Streamyx extends TMPoint{
    
     private String type, usage_time;
     Streamyx(String t, String u){
         type = t;
         usage_time = u;
     }
     void setType(String t ){
         type = t;
     }
     
     String getType(){
         return type;
     }
     void setUsageTime(String t ){
         usage_time = t;
     }
     
     String getUsageTime(){
         return usage_time;
     }
    
}


class Telephone  extends TMPoint{
    
     private String minuteUsed;
     Telephone(String t){
         minuteUsed = t;
        
     }
     
     void setMinuteUsed(String t ){
         minuteUsed = t;

     String getMinuteUsed(){
