In this post under Java Collections, I will show with example the purpose of Collections class static “disjoint” method. This method compares two collections provided as input and returns true if both the collections have no elements in common. For our example, we will use the below main class. Main class 1 package core.collection; 2…… Continue reading Collections disjoint method
