Question

void removeStudent()
{
System.out.print("\n Enter StudentID to remove: ");
long id =sc.nextLong();

int pos = searchStudentID(id);
if(pos == -1)
System.out.println("\n ERROR: No student found having same ID: " + id);
else
courses.remove(pos);
}

 

int searchStudentID(long studentID)
{
for(int c = 0; c < students.size(); c++)
if(studentID == students.get(c).getId())
return c;
return -1;
}

The code is supposed to prompt the user to enter a studentID and if it is in the records then it will be removed, but instead it just prompts me to enter and when i enter the ID, it just exits and goes back to the menu. is there something wrong with my code?
