Write a java program to find sum of all even and sum of all odd numbers in an array. 

program :

import java.util.*;
public class sum_of_odd_even
{
public static void main (String args[])
{
int i,n;
int so=0,se=0;
Scanner sc=new Scanner(System.in);

System.out.println("Enter the  size  of an array: ");
n=sc.nextInt();

int a[]=new int[n];
System.out.println("Enter the  elements of an array: ");
for(i=0; i<n; i++)
{
a[i]=sc.nextInt();
}
for(i=0; i<n; i++)
{
if(a[i]%2==0)
se+=a[i]; //sum of even
else
so+=a[i]; //sum of odd
}
System.out.println("sum of all even numbers="+se);
System.out.println("sum of all odd numbers="+so);
}
}


Output:
 Enter the  size  of an array:
8
Enter the  elements of an array:
1
2
3
4
5
6
7
8
sum of all even numbers=20
sum of all odd numbers=16


Or
Enter the  size  of an array:
5
Enter the  elements of an array:
6
10
5
14
25
sum of all even numbers=30
sum of all odd numbers=30

  Java Applet : Applet is a special type of program that is embedded in the webpage to generate the dynamic content. It runs inside the browser and works at client side. Applets are basically small java programs which can be transported from one computer from another computer in the network. Life cycle of Java Applet : Or Explain the life cycle  of an applet with  example? Or Describe different stage of life cycle of an applet? Applet is initialized. (Initial state) Applet is started.(running state) Applet is painted.(Display state) Applet is stopped.(idle or stoped state) Applet is destroyed.(dead state) When an applet is executed within the web browser or in an applet window, it goes through the four stages of its life cycle: initialized, started, stopped and destroyed.These stages correspond to the applet methods init(), start(), stop() and destroy() respectively.  -->All above mention methods are defined in java.applet.Applet class except paint...

Control Statements:Selection statement ,Iteration statement and Jump statement in Java

By
Control statements in java  : It is a statement that determines whether the other statements will be executed or not. It controls the flow of a program. control statements  help with the control flow of the program. Control flow is the order in which the statements execute.  Control Statements can be divided into three categories, namely A] Selection statement B] Iteration statement C] Jump statement Let us discuss above statements one by one as follow: A ] Decision-Making /Conditional /Selection statements: Statements that determine which statement to execute and when are known as decision-making statements. The flow of the execution of the program is controlled by the control flow statement. Selection statements allow your program to choose different paths of execution based upon the outcome of an expression or the state of a variable. Java supports two selection statements: I ] if statement: II ] switch statement: I] If st...
