Java program 6: 👇👇👇👇👇👇

1. Write a program to read integer value and display sum of all even and odd numbers (using array)

import java.util.Scanner;

public class EvenOddSum {

  public static void main(String[] args) {

  int i,esum=0,osum=0;

   System.out.println("enter size of array");

   Scanner sc=new Scanner(System.in);

   int s=sc.nextInt();

   System.out.println("Enter "+s+" element of array");

   int arr[]=new int[s];

   for( i=0;i<s;i++)

   {

   arr[i]=sc.nextInt();

  if(arr[i]%2==0)

    esum=esum+arr[i];

  else

    osum=osum+arr[i];

  }

  System.out.println("Sum of Even numbers: "+esum+"\nSum of odd numbers: "+osum);

}

}

Don't write this one it is for understanding purpose only ðŸ‘‡ðŸ‘‡ðŸ‘‡

esum-----> Even sum

osum-----> Odd sum

s-----------> size of array

arr--------> array name 

2. Write a program to perform linear search on a given number

import java.util.Scanner;

public class LinearSearch {

  public static void main(String[] args) {

  int i,flag=0,arr1[];

   System.out.println("enter size of array");

   Scanner sc=new Scanner(System.in);

   int s=sc.nextInt();

   System.out.println("Enter "+s+" element of array ");

    arr1=new int[s];

   for( i=0;i<s;i++)

   arr1[i]=sc.nextInt();

   System.out.println("enter element to search:");

   int sah=sc.nextInt();

   for(i=0;i<s;i++)

  if(arr1[i]==sah)

{

    flag =1;

    break;

    }

    if(flag==1){

System.out.println("element found at index:"+i);

System.out.println(i+1);}

else

System.out.println("element not found");

}

}

Don't write this one it is for understanding purpose only ðŸ‘‡ðŸ‘‡ðŸ‘‡

arr1-------++> Array name 

s-----------++-->Size

i-------------++--> for repetation 

sah----+--+-----> Search 

3. Write a program to find sum of 2 Matrix

import java.util.*;
public class MatrixSum {

  public static void main(String[] args) {
   int i,j,a[][],b[][];
   Scanner sc=new Scanner(System.in);
   System.out.println("Enter size1 & size2:");
   int s1=sc.nextInt();
   int s2=sc.nextInt();
System.out.println("Enter "+s1*s2+" element of 1st array: ");
   a=new int [s1][s2];
   for(i=0;i<s1;i++)
   {
   for(j=0;j<s2;j++)
   {
   a[i][j]=sc.nextInt();
   }}
   System.out.println("Enter "+s1*s2+" of 2nd array");
   b=new int [s1][s2];
   for(i=0;i<s1;i++){
   for(j=0;j<s2;j++){
   b[i][j]=sc.nextInt();
   }}
   System.out.println("Sum of 2 matrix is:");
   for(i=0;i<s1;i++){
   for(j=0;j<s2;j++){
   System.out.print(a[i][j]+b[i][j]+"\t");
   }
   System.out.println();
  }
}

Don't write this one it is for understanding purpose only 👇👇👇

i,j-------->  for repetation 

a[]--++---> first array

b[]---++---> Second Array

s1--++------> Size of Array

s2--++------> Size of  Array
