Java program to search for given item in a given array using liner search if item found then move it at top of array otherwise add at the end of array

Write a Program to search for given ITEM in a given array X[n] using liner search technique. If the ITEM is found, move it at top of array.if  the ITEM is not found, insert it at the end of the array.

import java.util.*;
class items
{
    public static void main(String args[])
    {
        Scanner sc=new Scanner(System.in);
        System.out.println("Enter a num");
        int c=sc.nextInt();
        String num[]=new String[c+1];
        int a,b=0,flag=0;

        System.out.println("Enter "+c+" Strings");
        for(a=0;a<c;a++)
        {
            num[a]=sc.next();
        }
        System.out.println("Enter a string to be searched");
        String n=sc.next();
        for(a=0;a<c;a++)
        {
            if(num[a].equalsIgnoreCase(n))
            {
                flag=1;
                b=a;
                break;
            }
        }
        if(flag==1)
        {
        System.out.println("no found at index no.:"+b);
            String temp=num[b];
            for(a=b;a>0;a--)
            {   
               num[a]=num[a-1];               
            }
            num[0]=temp;
            System.out.println("New array:");
        for(a=0;a<c;a++)
        {
            System.out.println(num[a]);
        }
        }
        
        else
        {
        System.out.println("String not found");
        num[c]=n;
        System.out.println("New array:");
        for(a=0;a<(c+1);a++)
        {
            System.out.println(num[a]);
        }
        }
        
    }
}
