Explanation / Answer

/*

*/

package schedule;

import java.util.Date;

/**
*
* @author allu
*/
public class Schedule {
int end;
String name;
int start;

public Schedule() {
}

public Schedule( String name, int start,int end) {
this.end = end;
this.name = name;
this.start = start;

}

  
}

first we write a schedule class in instant variblaes and canstracter

/*

*/

package schedule;

import java.io.IOException;
import java.util.ArrayList;
import java.util.Iterator;
import java.util.Scanner;

/**
*
* @author allu
*/
public class DayPlaner {
  
public static void main(String []a) throws IOException
{

  
ArrayList al=new ArrayList();
Scanner in = new Scanner(System.in);

for(int i=0;i<1||i<=al.size();i++)
{
System.out.print("Welcome to the day planner system");
System.out.print(" Enter 1 to add an activity:");
System.out.print(" Enter 2 to remove an activity:");
System.out.print(" Enter 9 to quit: ");
int num = in.nextInt();
String name;
  
switch (num) {
case 1: System.out.println("Enter the activity's name && time:");
al.add(new Schedule(in.next(),in.nextInt(),in.nextInt()));
Iterator itr=al.iterator();
while(itr.hasNext()){
Schedule ss=(Schedule) itr.next();
System.out.println(" task name:"+ss.name+" start time is:"+ss.start+" end time is"+ss.end);
}
// name = in.next();
break;
case 2: System.out.println("Enter the activity's name:");
Iterator itr2=al.iterator();
while(itr2.hasNext()){
Schedule ss2=(Schedule) itr2.next();
if(ss2.name==in.next()){

al.remove(ss2);
}else{

System.out.println(" task name:"+ss2.name+" start time is:"+ss2.start+" end time is"+ss2.end);
}
}
// name = "February";
break;
  
  
default: name = "Invalid number prease";
System.out.println("gud bye:");
break;
}
}
// System.out.println(s.a+num);
// System.out.println(name);

  
}}
  

next we set this logic and we get out put as below

output
