Explanation / Answer

Techniques which donot compare contents of array for checking equality are:
//here if statement is checking if both are same array
if(array1.equals(array2))
   System.out.println("They are same");
//here also if statement is checking if both array are same array.
if(array1 == array2)
   System.out.println("They are same");

Explanation:
int array1[]={2,4,5,6};
int array2[]=array1;
//here array1 and array2 are same array
//now if we check
if(array1.equals(array2))//it will return true
{
  
}
//but if two arrays are different

int array1[]={2,4,5,6};
int array2[]={2,4,5,6};
//and checking
if(array1.equals(array2))//it will return false,as both are not same array
{
  
}
//but function Arrays.equals(array1,array2) checks each elements of array.If elements of arrays are equal then it return true else false
