1. Let s1 be "Welcome" and s2 be "welcome". Write the code for the following statements: a. Replace all occurrences of the character e with E in s1 and assign the new string to s2. b. Split Welcome to Java and HTML into an array tokens delimited by a space and assign the first two tokens into s1 and s2. 2. Show the output of the following code and briefly explain your answer. public class Test { } public static void main(String[] args) { } System.out.println("Hi, ABC, good".matches("ABC")); System.out.println("Hi, ABC, good".matches(". *ABC. *")); System.out.println("A,B;C".replaceAll(",;", "#")); System.out.println("A, B; C".replaceAll("[,;]", "#")); String[] tokens = "A,B;C".split("[,;]"); for (int i = 0; i < tokens.length; i++) System.out.print(tokens[i] + " ");

4.33 LAB: Draw right-justified triangle (JAVA) Write a program in java to draw a right-justified triangle given the height as input. The first row has one asterisk (*) and increases by one for each row. Each asterisk is followed by a blank space and each row ends with a newline. Code starts here: import java.util.Scanner; public class LabProgram { public static void main(String[] args) { Scanner scnr = new Scanner(System.in); /* Type your code here. */ }}
Please code for me in JAVA Consider the following incomplete declaration of a Code class.Portions of the code may be hidden by changing the corresponding letter or digit to an X using the hide method.For example, suppose the following String object is• instantiated: String code = newString("ABCdef123ghi456jkIMNO*); The following code fragment results in the output indicated. Code FragmentString code2 = new String( hide(code, 2, 7) );System.out.println ( code2);Output ABXXXXX23ghi456jkIMNOThe Code class also has a wordTriangle method, which doesn't return anything but takes in a String parameter and prints out a "word triangle" based on that word. For example, the method call to wordTriangle( "triangle" ) would result in the following output: triangle triangl triang trian tria tri tr t public class Code { // precondition: p1 >= 0, p1 < p2 // p2 <= mCode.length // Replaces the characters in the code starting at // position p1 until p2-1, inclusive, with an Xpublic String…

Please complete the task by yourself only in JAVA with explanation. Don't copy. Thank you. Using quicksort to sort an array of car objects by various criteria. Define a class Car as follows: class Car { public String make; public String model; public int mpg; // Miles per gallon } c) Implement a comparator called CompareCarsByMakeThenDescendingMPG that can be passed as an argument to the quicksort method from the lecture notes. CompareCarsByMakeThenDescendingMPG should return a value that will cause quicksort to sort an array of cars in ascending order by make and, when two cars have the same make, in descending order by mpg.
6. a. Fast in java coding please. Thank you 1. Why should you use StringBuffer objects instead of String objects in aprogram that makes lot of changes to strings?2. Each of the numeric wrapper classes has a static toString method. Whatdo these methods do?
1. Given a string of at least 3 characters as input, if the length of the string is odd return the character in the middle as a string. If the string is even return the two characters at the midpoint. public class Class1 { public static String midString(String str) { //Enter code here } } ----------- 2. Given an array of integers return the sum of the values stored in the first and last index of the array. The array will have at least 2 elements in it public class Class1 { public static int endSum(int[] values) { //Enter code here } } ----------- 3. The method takes a string as a parameter. The method prints treat if the string is candy or chocolate (of any case, such as CaNdY) Otherwise print trick import java.util.Scanner; public class Class1 { public static void trickOrTreat(String str) { //Enter code here } public static void main(String[] args) { Scanner s = new Scanner(System.in); trickOrTreat(s.nextLine()); } }
