In this post, we will learn Search a Course Program in java Programming language.
Question:
IIHT institution is offering a variety of courses to students. Students have a facility to check whether a particular course is available in the institution. Write a program to help the institution accomplish this task. If the number is less than or equal to zero display “Invalid Range”.
Assume maximum number of courses is 20.
Sample Input 1:
Enter no of course:
5
Enter course names:
Java
Oracle
C++
Mysql
Dotnet
Enter the course to be searched:
C++
Sample Output 1:
C++ course is available
Sample Input 2:
Enter no of course:
3
Enter course names:
Java
Oracle
Dotnet
Enter the course to be searched:
C++
Sample Output 2:
C++ course is not available
Sample Input 3:
Enter no of course:
0
Sample Output 3:
Invalid Range
CODE:–
import java.util.*;
public class Course
{
public static void main (String[] args) {
Scanner sc=new Scanner(System.in);
System.out.println("Enter no of course:");
int no_crs=sc.nextInt();
if(no_crs>0)
{
System.out.println("Enter course names:");
String crs[]=new String[no_crs];
for(int i=0;i<no_crs;i++)
{
crs[i]=sc.next();
}
System.out.println("Enter the course to be searched:");
String srch=sc.next();
int flag=0;
for(int i=0;i<no_crs;i++)
{
if(srch.equals(crs[i]))
{
flag++;
}
}
if(flag!=0)
{
System.out.println(srch+" course is available");
}
else
{
System.out.println(srch+" course is not available");
}
}
else
{
System.out.println("Invalid Range");
}
}
}
