Question Question 8
Write a program to accept the year of graduation from school as an integer value from the user. Using the binary search technique on the sorted array of integers given below, output the message "Record exists" if the value input is located in the array. If not, output the message "Record does not exist".
{ 1982, 1987, 1993, 1996, 1999, 2003, 2006, 2007, 2009, 2010 }
import java.util.Scanner;
public class KboatGraduationYear
{
public static void main(String args[]) {
Scanner in = new Scanner(System.in);
int n[] = {1982, 1987, 1993, 1996, 1999, 2003,
2006, 2007, 2009, 2010};
System.out.print("Enter graduation year to search: ");
int year = in.nextInt();
int l = 0, h = n.length - 1, idx = -1;
while (l <= h) {
int m = (l + h) / 2;
if (n[m] == year) {
idx = m;
break;
}
else if (n[m] < year) {
l = m + 1;
}
else {
h = m - 1;
}
}
if (idx == -1)
System.out.println("Record does not exist");
else
System.out.println("Record exists");
}
}Output
