1.  Write a program to display sum of array elements at run-time

package pow;

import java.util.Scanner;

public class SumArry {

  public static void main(String[] args) {

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

   Scanner sc=new Scanner(System.in);

   int s=sc.nextInt();

   System.out.println("Enter "+s+" element of 1st array");

   int arr1[]=new int[s];

   for(int i=0;i<s;i++)

   {

   arr1[i]=sc.nextInt();

   }

   System.out.println("Enter "+s+" element of 2nd array");

   int arr2[]=new int[s];

   for(int i=0;i<s;i++)

   {

   arr2[i]=sc.nextInt();

   }

   int sumArr[]=new int[s];

  for(int i=0;i<s;i++){

   sumArr[i]=arr1[i]+arr2[i];

   System.out.print(sumArr[i]+" ");

   }}}

2. Write a program to find minimum and maximum element in an array.

package pow;

import java.util.Scanner;

public class Armstrongp {

  public static void main(String[] args) {

  int i;

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

   Scanner sc=new Scanner(System.in);

   int s=sc.nextInt();

   System.out.println("Enter "+s+" element of 1st array");

   int arr1[]=new int[s];

   for( i=0;i<s;i++)

   {

   arr1[i]=sc.nextInt();

   }

  int max= arr1[0];

  int min= arr1[0];

  for(i=0;i<s;i++)

  {

  if(arr1[i]>max)

  max=arr1[i];

  if(arr1[i]<min)

  min =arr1[i];

}

System.out.print("Maximum number: "+max+" minimum number: "+min);

}

}


I am not responsible if any thing goes wrong due to these programs

If anyone not getting these programs just fell free to call.
