Accept n strings. Sort names in ascending order.

in this tutorial we are learn about sort a name in ascending accepting n number of string.

Code:

import java.util.Scanner;

public class QuadraticEquation

{

public static void main(String []args)

{

int a,b,c;

double root1,root2,d;

Scanner s=new Scanner(System.in);

System.out.println("Given quadratic equation:ax^2+bx+c");

System.out.print("Enter a:");

a=s.nextInt();

System.out.print("Enter b:");

b=s.nextInt();

System.out.print("Enter c:");

c=s.nextInt();

System.out.println("Given quadratic equation:"+a+"x^2+"+b+"x+"+c);

d=b*b-4*a*c;

if(d>0)

{

System.out.println("Roots are real and unequal");

root1=(-b+Math.sqrt(d))/(2*a);

root2=(-b-Math.sqrt(d))/(2*a);

System.out.println("First root is:"+root1);

System.out.println("second root is:"+root2);

}

else if(d==0)

{

System.out.println("Roots are real and equal");

root1=(-b+Math.sqrt(d))/(2*a);

System.out.println("Root:"+root1);

}

else

{

System.out.println("Roots are imaginary");

}

}

}

output:
