Course.java

import java.util.Scanner;

public class Course {

   public static void main(String [] args){
       String courseName="";
       String time = "";
       boolean courseFound =false;
       //Creating course details array and Storing values in Course Details Array
       String[][] courseDetailsArray = {{"COP 2800","Wed 10:00am"},{"COP 2801","Thur 10:00am"},{"COP 2802","Fri 10:00am"},{"COP 2803","Mon 10:00am"}};
      
      
       //Reading the course name from user
       Scanner scan = new Scanner(System.in);
       System.out.println("Please enter a Course Name :");
       courseName = scan.nextLine();
      
       //looping through each row
       for(int i=0;i<4;i++){
          
           //looping through each column
           for(int j=0;j<2;j++){
               String arrayElement = courseDetailsArray[i][j];
               if(courseName.equalsIgnoreCase(arrayElement)){
                   //if the Coursename matche with courseDetailsArray[i][j]
                   //get the next element of the same row as time
                   time = courseDetailsArray[i][j+1];
                   courseFound = true; //Setting the flag for row loop
                   break; // break the iteration
               }
           }
           if(courseFound){
               break;
           }
      
           }
      
       //Printing the details
       if(courseFound){
           System.out.println("Course Time is : "+time);
       }
       else{
           System.out.println("Course not found");
       }
      
   }
}

Sample output:

Please enter a Course Name :
COP 2800
Course Time is : Wed 10:00am

Please enter a Course Name :
