Collection filter using Java 8

collectionFilterJava8.java

ArrayList<String> owners = new ArrayList<String>();
ArrayList<String> owner1Teams = new ArrayList<String>();
		
//Creating the unfilter collection
		
owners.add("Owner 1 - Team 1");
owners.add("Owner 1 - Team 2");
owners.add("Owner 2 - Team 1");
owners.add("Owner 2 - Team 2");
		
//This will filter only the teams owned by Owner 1
Predicate<String> ownerFilter = (String ownerName) -> ownerName.contains("Owner 1");
		
//Actual use of the predicate, adding in owner1Teams collection the teams owned by Owner 1
owners.stream().filter(ownerFilter).forEach(team -> owner1Teams.add(team));
		
//Printing the results
for(String team : owner1Teams){ System.out.println(team); }
