Java Examples - Collection Comparison
Java ExamplesThe following example converts a string to a collection and uses Collection.min() and Collection.max() from the Collection class to compare elements in the collection:
Main.java file
import java.util.Collections;
import java.util.Set;
import java.util.TreeSet;
class Main {
public static void main(String[] args) {
String[] coins = { "Penny", "nickel", "dime", "Quarter", "dollar" };
Set<String> set = new TreeSet<String>();
for (int i = 0; i < coins.length; i++) {
set.add(coins[i]);
}
System.out.println(Collections.min(set));
System.out.println(Collections.min(set, String.CASE_INSENSITIVE_ORDER));
for (int i = 0; i <= 10; i++) {
System.out.print("-");
}
System.out.println("");
System.out.println(Collections.max(set));
System.out.println(Collections.max(set, String.CASE_INSENSITIVE_ORDER));
}
}
The output from running the above code is:
Penny dime ----------- nickel QuarterOther Extensions
