// 7. Create a class as Student. Write a program in Java to display the names and roll
// numbers of students. Create an array of 10 students and initialize the array with
// user input. Handle ArrayIndexOutOfBoundsExeption, so that any such problem doesn’t
// cause illegal termination of program. Read a character from user and display the
// student names starting with given character.
