Programs of Array Operations

Explore how to implement key array operations in Java including union, intersection, and difference of sorted arrays. Learn to handle duplicates and create unique value arrays, enhancing your ability to solve complex programming problems with arrays.

We'll cover the following...

The union of two arrays

The union operation combines two sets, skipping the matching values of both sets while populating the resultant set.

Unlike sets, arrays may contain duplicate values. For example:

  • The union of {2,5,8,9,30,45}\{2,5,8,9,30,45\} and {4,5,6,7,8,9,10}\{4,5,6,7,8,9,10\} should be {2,4,5,8,9,10,30,45}\{2,4,5,8,9,10,30,45\}.

  • The union of {2,5,5,8,9,30,45}\{2,5,5,8,9,30,45\} ...
