Write an application that counts by five from 5 through 500 inclusive, and that starts a new line after every multiple of 50 (50, 100, 150, and so on). public class CountByFives { public static void main (String args[]) { // Write your code here } }

public static String[] getTokens(String raw, String delimiter){ // Line #1 goes here... int numTokens = st.countTokens(); // Line #3 goes here... for(int i = 0; i < numTokens; i++){ // Line #5 goes here } // Line #7 goes here } Using the code above, which one of these should be the code for "Line #7": ret[i] = st.nextToken(); return ret; String[] ret = new String[numTokens]; StringTokenizer st = new StringTokenizer(raw, delimiter);

Problem 1: Complete the sumOfDiagonals method in SumOfDiagonals.java to do the following: The method takes a 2D String array x as a parameter and returns no value. The method should calculate and print the sum of the elements on the major diagonal of the array x. In order to have a major diagonal, the array passed into the method should be a square (n-by-n), if it's not a square your program should handle that situation by throwing an exception. (Do Not worry about ragged arrays) If the array is a square, but there is a non-integer value on the major diagonal, your program should handle that situation by throwing an exception. When handling the exceptions, be as specific as you can be, (i.e. Do Not just use the Exception class to handle all exceptions in one catch block). Make the proper calls to the sumOfDiagonals method from the main method to test your sumOfDiagonals method on all the String arrays provided in the main method.

String spell = "Redikulus"; How would you find the index of the 'u' just before the last 's' using a single line of code? Multiple answers may be correct. Given the string String spell = "Redikulus"; How would you find the index of the 'u' just before the last 's' using a single line of code? Multiple answers may be correct. A. spell.substring(5, spell.length()).indexOf('u'); B. spell.indexOf('u', 5); C. spell.lastIndexOf('u'); D. spell.contains('u'); E. spell.indexOf('u', spell.length() - 2); F. spell.indexOf('u', spell.indexOf('l'));

class Lab4Q1P3 { public static void main(String args[]) { int max = 10;while (max < 10) {System.out.println("count down: " + max);max--;}}} Do you know what is wrong with the program? I know that there is error on the 7th line but I don't know what to fix.

Practice / Frequency of Characters Write a method that returns the frequency of each characters of a given String parameter. If the given String is null, then return null If the given String is empty return an empty map Example input: output: empty map explanation: input is empty Example input: null output: null explanation: input is null. Since problem output is focused on the frequency we can comfortably use Map data structure. Because we can use characters as key and the occurrences of them as value. Example input: responsible output: {r=1, e=2, s=2, p=1, o=1, n=1, i=1, b=1, l=1} explanation: characters are keys and oc values ences are

strobogrammatic number is a number that looks the same when rotated 180 degrees (looked at upside down). Find all strobogrammatic numbers that are of length = n.

In an SSL protocol, what are the four most important record subtypes to check for? Where do these symbols come from, and what do they represent?

Please do not use string methods except to find method

Repeating String Write a method that takes a String and an int and return a String that is the original String repeated n times. For example, repeatString("Famous", 3) should return "FamousFamousFamous" The method signature should be public String repeatString(String str, int n) public String repeatString(String str, int n) { //declare a string variable //set up statements for repeating n number of times //create the appropriate return statement }
