Write a Java program to insert an element into the array.
PROGRAM :
import java.util.*;
class arrinsert
{
public static void main(String[] args)
{
int n,pos,x;
Scanner sc=new Scanner(System.in);
System.out.print("\nEnter size of array : ");
n=sc.nextInt();
int a[]=new int[n+1];
System.out.print("\nEnter all the elements of array : \n");
System.out.println();
for(int i=0; i<n; i++)
{
a[i]=sc.nextInt();
}
System.out.println("\nBefore insertion the array is :");
for(int i=0; i<n; i++)
{
System.out.print(a[i]+" ");
}
System.out.println();
System.out.print("\nEnter the position where you want to insert the element: ");
pos=sc.nextInt();
System.out.print("\nEnter the element you want to insert : ");
x=sc.nextInt();
for(int i=(n-1); i>=(pos-1); i--)
{
a[i+1]=a[i];
}
a[pos-1]=x;
System.out.println("\nAfter insertion");
for(int i=0; i<n; i++)
{
System.out.print(a[i]+",");
}
System.out.print(a[n]);
}
}
