comparing arrays in java along with index position [closed]

Answer 1

Disclaimer: Did not even bother to compile this and omit any error handling:

/*Returns the equal count in int[0] and nonEqualCount in int[1] of the result*/
public static int[] findEqualAndNotEqual(Integer firstArray, Integer secondArray){  
   Set set = new HashSet(Arrays.asList(firstArray));    
   int equalCount = 0;  
   int nonEqualCount = 0;  
   for(Integer num:secondArray){  
      if(set.contains(num)){
         equalCount++;   
      }
      else{
         nonEqualCount++;
     }  
   }
   return new int[]{equalCount, nonEqualCount};  
}
