The subexpression “[ ]” matches all the characters specified in the braces. Therefore, to move all the upper case letters to the end of a string −Iterate through all the characters in the given string.Match all the upper case letters in the given string using the regular expression "[A-Z]".Concatenate the special characters and the remaining characters to two different strings.Finally, concatenate the special characters string to the other string.Example 1public class RemovingSpecialCharacters { public static void main(String args[]) { String input = "sample B text C with G upper case LM characters in between"; ...

The \b meta character in Java regular expressions matches the word boundaries Therefore to find a particular word from the given input text specify the required word within the word boundaries in the regular expressions as −"\brequired word\b";Example 1import java.util.Scanner; import java.util.regex.Matcher; import java.util.regex.Pattern; public class MachingWordExample1 { public static void main( String args[] ) { //Reading string value Scanner sc = new Scanner(System.in); System.out.println("Enter input string"); String input = sc.next(); //Regular expression to find digits String regex = "\bhello\b"; ...

The java.util.regex.Matcher class represents an engine that performs various match operations. There is no constructor for this class, you can create/obtain an object of this class using the matches() method of the class java.util.regex.Pattern.The usePattern() method of the Matcher class accepts a Pattern object representing a new regex pattern and uses it to find matches.Exampleimport java.util.Scanner; import java.util.regex.Matcher; import java.util.regex.Pattern; public class UsePatternExample { public static void main(String[] args) { Scanner sc = new Scanner(System.in); System.out.println("Enter input text: "); String input = sc.nextLine(); String regex = "[#%&*]"; ...

Given with the points (x1, y1, z1), (x2, y2, z2), (x3, y3, z3) and (x4, y4, z4) and the program must check whether the given points are coplanar or not. Points are said to be coplanar is they lie under same plane and if they are under different-2 planes than the points are not coplanar.Given below is an image containing four points and all are under same plane which is xy plane that means points are coplanarGiven below is an image containing four points and all are under different planes which shows points are not coplanarExampleInput-: x1 = 2, y1 ...

Given with an array of amount invested by multiple person and another array containing the time period for which money is invested by corresponding person and the task is to generate the profit sharing ratio.What is Profit Sharing RatioIn a partnership firm, profits and losses are shared between the partners depending upon the capital invested by them in the business. On the basis of that capital investment percentage we calculate the profit sharing ratio which shows the amount of profit which is to be given to each partner of a business.Formula − Partner 1 = capital invested * time period ...

Given with the positive integer value n and the task is to generate the number of odd days till the given year n.ExampleInput-: days = 500 Output-: number of odd days are: 5 Input-: days = 400 Output-: number of odd days are: 0How to calculate the number of odd days in given number of yearsFor calculating the number of odd days the first thing we need to check is whether the given year is a leap year or not because if it’s a leap year than the number of odd days will get changed. If the year is divisible ... Read More
