Sample Solution:

Java Code:

import java.util.*; 
import java.io.*; 
 public class Exercise97 {
 public static void main(String[] args)
 {
	  int[] array_nums = {10, 20, 10, 50, 20, 13, 50};
	//int[] array_nums = {10, 10, 50, 50, 20, 13, 50};
      boolean testd = false;
	  int result=0;
	  int x = 10;
	      
	for(int i = 0; i < array_nums.length - 1; i++) {
        if(array_nums[i] == x && array_nums[i+1] == x)
            {
         System.out.printf( String.valueOf(true));	
         result = 1 ;
		}
                  
        if(i <= array_nums.length - 3 && array_nums[i] == x && array_nums[i+2] == x)
           {
         System.out.printf( String.valueOf(true));	
         result = 1 ;
		}
    }
	
	 if (result==0)                             
	   {	 
         System.out.printf( String.valueOf(false));
	    }
		System.out.printf("\n");
    }
}

Sample Output:

Previous: Write a Java program to check if there is a 10 in a given array of integers with a 20 somewhere later in the array.
Next: Write a Java program to check if the value 20 appears three times and no 20’s are next to each other in an given array of integers.
