Sample Solution:

Java Code:

import java.util.*; 
import java.io.*; 
 public class Exercise99 {
 public static void main(String[] args)
 {
	int[] array_nums = {10, 20, 10, 20, 40, 20, 50};
	int result = 0;	
	int x = 20;
	for(int i = 0; i < array_nums.length - 1; i++) {
        if(array_nums[i] != x && array_nums[i + 1] != x)
		{
                                result = 1;	
		}        
    }                                   
    if (result==0)
 	  {
     	 System.out.printf( String.valueOf(true));
