Write a Program in java that prints all real solutions to the quadratic equations ax2+bx+c=0. Read a,b,c and use the quadratic formula. If the discriminate b2-4ac is negative, display a message stating there are no real solutions.

Write a Program in java that prints all real solutions to the quadratic equations ax2+bx+c=0.

import java.util.Scanner; 
class quads{ 
 public static void main(String[] args) { 
  Scanner sc = new Scanner(System.in); 
  System.out.println("Eneter the value of a : "); 
  double a = sc.nextDouble(); 
  System.out.println("Enter the value of b : "); 
  double b = sc.nextDouble(); 
  System.out.println("Enter the value of c : "); 
  double c = sc.nextDouble(); 
  double d = b * b - 4 * a * c; 
  if (d > 0.0) { 
   double r1 = (-b + Math.pow(d, 0.5)) / (2.0 * a); 
   double r2 = (-b - Math.pow(d, 0.5)) / (2.0 * a); 
   System.out.println("The roots are " + r1 + " and " + r2); 
  } 
  else if (d == 0.0) { 
   double r1 = -b / (2.0 * a); 
   System.out.println("The root is " + r1); 
  } 
 else { 
  System.out.println("Roots are not real."); 
 } 
 sc.close(); 
 }
}



OUTPUT:

Enter the value of a :
1
Enter the value of b :
5
Enter the value of c :
2
The roots are -0.4384471871911697 and -4.561552812808831

creating object invoking various methods

Define a class named College as described below:  Data Members: 1) collegeName 2) principalName 3) place Methods : 1) constructor. 2) display() to display the collegeName, principalName, and the place. Test this class by creating an object and then invoking the various methods. class collegeName{  public String collegeName;  public String PrincipalName;  public String place;  public collegeName(){  }  public void display(){  System.out.println("College name is "+this.collegeName);  System.out.println("Principal name is "+this.PrincipalName);  System.out.println("Place is "+this.place);  }  }  class displayName{  public static void main(String[] args) {  collegeName c = new collegeName();  c.collegeName="Siliguri Institute of Technology";  c.PrincipalName="Dr. Mithun Chakraborty";  c.place="Siliguri";  c.display();  }  } OUTPUT: College name is Siliguri Institute of Technology Princip...

Networking Interview Questions and Answers

Networking Interview Questions and Answers 1) What is a Network? Answer: The network is defined as a set of devices connected to each other through a physical transmission medium. For example, a computer network is a group of computers connected to each other to communicate and share information and resources such as hardware, data, and software. In a network, nodes are used to connect two or more networks. 2) What is a Node? Answer: Two or more computers are directly connected by fiber optics or any other cable. A node is a point where a connection is established. It is a network component used to send, receive, and forward electronic information. A device connected to a network is also called a Node. Let us consider that in a network there are 2 computers, 2 printers, and a server connected, then we can say that there are five nodes in the network. 3) What is Network Topology? Answer:  Network topology is a physical layout of the computer network and defines how computers,...
