Java Exercise : Write a program to list all even numbers between two numbers

Here you will learn to write a program for listing out all the even numbers between two numbers. For this first create a class named AllEvenNum under the java.io package. Now use the try/catch exception to avoid any kind of input error. After this create a buffer class in which all the input data are stored and modified. Then give message as to "Enter number" in the System method. 

As we have to find out all the even numbers between 1 and the input number, define an integer variable 'num'. Now apply ParseInt method that parses the string character into decimal integer. Again apply for loop in which define an integer i=1 and i<=  num also with an increment operator. Then apply the if condition that i/2=0 i.e. to find even numbers which are divided by the integer 2. In the end apply the catch exception. 

Now and compile and run the program, and enter your desired number to get all even numbers between 1 and this numbers. 

Here is the code of program:

import java.io.*;

class AllEvenNum{
  public static void main(String[] args) {
    try{
      BufferedReader br1 = new BufferedReader(new InputStreamReader(System.in));
      System.out.println("Enter number : ");
      int num = Integer.parseInt(br1.readLine());
      System.out.println("Even Numbers:");
      for (int i=1;i <=num ; i++){
        if(i%2==0 ){
          System.out.print(i+",");
        }
      }
    }
    catch(Exception e){}

  }
}
