In this article, we will learn how to find the lowest and highest values in a TreeSet in Java. The TreeSet class, part of the java.util package, automatically sorts its elements in natural order. We will use the first() and last() methods of the TreeSet class to retrieve the smallest and largest elements, respectively Problem Statement Write a Java program to get the lowest and highest value in TreeSet. Input 50, 100, 150, 200, 250, 300, 400, 500, 800, 1000 Output TreeSet Lowest value = 50TreeSet Highest value = 1000 Steps to get the lowest and highest value in TreeSet ... Read More
In this article, we will learn to split a string in Java using regular expressions. We will be using the split(String regex) method of the String class to split this string around matches of the given regular expression. This method works in the same way as invoking the method i.e. split(String regex, int limit) with the given expression and a limit argument of zero. Therefore, trailing empty strings are not included in the resulting array. Steps to split string in Java using regular expression Following are the steps to split strings in Java using regular expression − ... Read More
