Simple programs in JAVA

JAVA is dynamic programming language. It is capable of making simple program to complex. We can make simple program of add, even numbers, odd numbers.

First program of adding two numbers in JAVA

Add.java

public class Add {

    public static void main(String[] args) {
        int a=5;
        int b=2;

        int result=a+b;

        System.out.print("Additon of a and b :"+result);

    }

}

Second program of subtraction two numbers in JAVA

Subtract.java

public class Subtract {

    public static void main(String[] args) {
         int a=5;
         int b=2;

         int result=a-b;

         System.out.print("Subtraction of a and b :"+result);

    }

}

Third program of print even numbers in JAVA

EvenNumber.java

public class EvenNumber {

    public static void main(String[] args) {
        for(int i=0;i<=10;i++)
         {
          if((i%2)==0)
          {
           System.out.println("Even number  :"+i);
          }
         }
    }
}

Forth program of print odd numbers in JAVA

OddNumber.java

public class OddNumber {

    public static void main(String[] args) {
        for(int i=0;i<=10;i++)
         {
          if((i%2)!=0)
          {
           System.out.println("Odd number  :"+i);
          }

    hi all, i have looked in the internet for a count down program in java but never found a simple 1, so i made 1, notice i used kdr.java u can find it on the internet its very usefull. the program is simple using while loop he is the code:

    //Program: Count down to Zero

    // programmer: Omar Ibrahim :D

    public class CountDown {
    public static void main(String args[]) {
    int number;
    boolean value;

    System.out.print(”Input number to count down to zero:”);
    number = Keyboard.readInt();

    do{
    value= true;
    number = number -1;
    System.out.print(”\n”+number);
    kdr.waitsometime(1000);
    if (number != 0) {
    value = false;
    }
    }while (!value);

    }
    }
