18. Relational Operators and Arrays

• The expression (array1 == array2) determines if the determines whether array1 and array2 refer to the same array in memory:

  
      if ( array1 == array2 ) {
          //...
      }
  
  

• To determine whether arrays contain the same elements, you can compare them element by element

• You can write a method that returns true if two int arrays contain the same elements
