Explanation / Answer

Program plan:As per the question the two dimensional array can be created which holds the course names and the date and time for the meeting.

Program:

package practice;

import java.util.*;

public class Schedule {

public static void main(String args[])

{

int x=0;

String[][] course={

{"CIS100","mon 10.00"},

{"CIS101","tue 11.00"},

{"CIS102","wed 10.30"},

{"CIS103","thu 10.00"},

{"CIS104","fri 11.00"}};

Scanner s=new Scanner(System.in);

System.out.println("enter coutrse name to get schedule:" );

String c=s.next();

for(int i=0;i<5;i++)

{

if(course[i][0].equalsIgnoreCase(c))

{

for(int j=0;j<2;++j)

{

System.out.println("course time is"+course[i][j]);

}

}

else x++;

}

if(x!=0)

System.out.println("COurse not listed");

}

}

Sample output:
