#Java - Code Snippets for '#Java.util.IntSummaryStatistics' - 1 code snippet(s) found

 Sample 1. Combine two Summaries and Generate a new Summary using Lambda Expression

// Populate a List using Set elements.

// Declare and Initialize the Collection

Set<Integer> intSet = new HashSet<Integer>();
Set<Integer> intSet2 = new HashSet<Integer>();

// Add Elements

intSet.add(1);
intSet.add(2);
intSet.add(3);
intSet.add(4);
intSet2.add(1);
intSet2.add(2);
intSet2.add(3);
intSet2.add(4);

// Use the stream and collectors to Summarize all Integer elements

IntSummaryStatistics summary = intSet.stream().collect(Collectors.summarizingInt(p->((Integer)p)));

summary.combine(intSet2.stream().collect(Collectors.summarizingInt(p->((Integer)p))));

System.out.println(summary); // Prints IntSummaryStatistics{count=8, sum=20, min=1, average=2.500000, max=4}
