Program to check whether number is prime or not in java

Write a Java program to find whether the given number is prime or not.





import java.io.*;
class prime{
  public static void main(String[] args)
 {
    int num,i;
try{
BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
System.out.println("Enter number:");
num=Integer.parseInt(br.readLine());
  
     for (i=2; i < num ;i++ )
{
       int n = num%i;
     if (n==0)
{
         System.out.println("not Prime!");
         break;
     }
     }
     if(i == num)
{
       System.out.println("Prime number!");
     }
}catch(IOException e){}
  }
}

Command Line argument + IndexOf() program

Write a program that take a string and a character to be searched from command line input in the string 
and count the occurrence of that character in string and also display the appropriate message.




 //file name is cmd.cs
/* pass string without space in command line argument
*/

using System;
public class cmd{
public static void Main(string []args)
{
string str=args[0];
string s=args[1];
int ind=str.IndexOf(s);
Console.WriteLine("occurrence of {0} in {1} is : {2} ",s,str,ind);
}
}

ORATOR OVERLOADING IN C#

Write a program to add two complex number by overloading + operator.

using System;
public class Complex
{
    public int real;
    public int imaginary;

    public Complex(int real, int imaginary)
    {
        this.real = real;
        this.imaginary = imaginary;
    }

    public static Complex operator +(Complex c1, Complex c2)
    {
        return new Complex(c1.real + c2.real, c1.imaginary + c2.imaginary);
    }

public void show()
{
Console.WriteLine("{0} + {1}i", this.real, this.imaginary);
}
}

class overloadplus
{
    static void Main()
    {
        Complex num1 = new Complex(12, 8);
        Complex num2 = new Complex(21, 4);
        Complex sum = num1 + num2;

        Console.WriteLine("First complex number:");
        num1.show();
        Console.WriteLine("Second complex number:") ;
        num2.show();
        Console.WriteLine("The sum of the two numbers:");
        sum.show();
    }
}



+++++++++++++++OUTPUT+++++++++++++++++++++
First complex number:                                
12 + 8i
Second complex number:
21 + 4i
The sum of the two numbers:
33 + 12i
