Determine If Lengths Of Three Strings Are In Order By Length / Smallest To Largest
Feb 18, 2015
Suppose s, t, and w are strings that have already been created inside main. Write a statement or statements, to be added to main, that will determine if the lengths of the three strings are in order by length, smallest to largest. That is, your code should determine if s is strictly shorter than t, and if t is strictly shorter than w. If these conditions hold your code should print (the boolean value) true. If not, your code should print false. (Strictly means: no ties)

/*
Purpose: To write the methods and the rest program. The program should fill a 4 X 4 2 dimensional array with random numbers between 100 and 200. The program should then determine and print the largest and smallest values within the array using two Methods Largest and Smallest. The program should then determine and print the number of values within the array that are even using a function called Even. The program should also enter a loop that will only terminate when the user inputs a -1 as a choice. The loop should continue to ask the user to guess a number that was randomly generated. The program should call the Findit function to determine if the number was in the array. The program should print out the values in the array when the user selects a -1 and then terminate.

Write a program that finds both the largest and smallest of several integers. T. For example, a program that determines the winner and loser of a sales contest would input the number of units sold by each salesperson. The salesperson who sells the most units wins the contest; the salesperson who sells the least units loses the contest. Write a pseudocode program, then a Java program that inputs a series of 10 integers and determines and prints the largest integer and the smallest integer. Your program should use at least the following four variables: counter, number , largest and smallest. After i run the code i just get the largest input without the smallest .
This is my code :
import java.util.Scanner; // program uses scanner
// main Class begins
public class Largest12
{
public static void main(String[] args) //main method begins
{
//Initial variables
int counter = 0; // initiate counter
int number=0 ;

I know it is possible to do this using the Array class but I don't want to use that. I am trying to use selection or bubble sort but I believe selection is what I want. This program asks the user to input 2 arrays with 10 integers each, sorts them from smallest to largest, then states whether they are the same or not. Comparing the two arrays.
import java.util.Scanner;
public class SetDifference
{
public static void main (String args[])
{
Scanner sc = new Scanner (System.in);
int array1[] = new int[10];
int array2[] = new int[10];

Here is a simple program on applets that is giving me a bit of headache since it cannot always display the two numbers that it is supposed to: the largest and smallest of the five input integers.....I cannot see where i went wrong, you can always create separately the HTML file to load the applet in an appletviewer of your won size.

23.6 (Largest and Smallest) Write an applet that reads five integers, determines which are the largest and smallest integers in the group and prints them. Draw the results on the applet.

I have to create a method with the following header :
public static <E extends Comparable<E> > void sort ( ArrayList<E> list , int left, int right)
i also had to create a swap cells method and position of max integer method. and also had to read the preserved data file in with a scanner. I implemented the comparable interface I am having difficulty sorting my list by the area. It has to be in descending order.
Geometric Object class: since it has comparator also am interested if i need to change this?
CODE:
Driver:
public static void main(String[] args) throws IOException, ClassNotFoundException {
Circle c1 = new Circle (4, "red", false);
Circle c2 = new Circle (2, "blue", true);
Circle c3 = new Circle (10, "blue", true);
Rectangle r1 = new Rectangle (10, 6, "yellow", true);
Rectangle r2 = new Rectangle ( 5, 11, "green", true);
ArrayList <GeometricObject> list = new ArrayList();

These are all arraylists and not arrays
I have currently two arrays.
Java Code:
String[] chunks = {"a","b","c"};
int[] freq = {2,4,3}; mh_sh_highlight_all('java');
I am looking for a way to order these from greatest to smallest based on frequency.
The resulting arrays should be:
Java Code:
chunks = {"b","c","a"};
freq = {4,3,2}; mh_sh_highlight_all('java');
Because b is most frequent, and a is least frequent.
One way I can think of doing this is a two dimensional String array
Java Code: String[][] fullHold = {{"b","c","a"},{"4","3","2"}}; mh_sh_highlight_all('java');
Then sort based on the character values of the second row.
How can I sort a two dimensional array based on a single row (where it will rearrange the other rows in accordance).

You are to design a Java application to carry out additions and subtractions for numbers of any length. A number is represented as an object which includes a sign and two strings for the whole and decimal parts of the number. And, the operations must be done by adding or subtracting characters directly. You are not allowed to convert these strings to numbers before the operation.
The program must use a "Number" class which includes at least the following methods:
Number ( );
Number (double n);
Number add (Number RHS);
Number subtract (Number RHS);
String toString ( );
This is what i have but it only adds positive numbers and it doesn't subtract problems like 7.05-8.96. Also some of it was what our teacher gave us like alignwhole method
import java.util.Scanner;
public class Number{
private String whole;
private String decimal;
private String sign;
public static void main (String[] args){
System.out.println("Enter two numbers");
[code]....

Here's the code: it's while loop inside a for loop to determine the proper length of a variable:
for (int i = 0; i < num; i++) {
horse[i]=new thoroughbred();
boolean propernamelength = false;
while (propernamelength==false){
String name = entry.getUserInput("Enter the name of horse "
[code]....
I was just wondering what was going on here -- I've initialized the variable, so why do I get this message? (actually the carat was under the variable name inside the parentheses.

I'm doing an exercise we're you're supposed to sort strings in alphabetical order, without importing anything , not using the Arrays.sort() method.
I think I got the method down partially right, or it is on the right track, but it is completely not being applied to my answer. All it prints out in the console is the actual String array twice, without sorting anything.
public class arrayofstrings {
public static void sort(String[] a) {
String temp= "";
int min;
int i= 0;
for (int j=0; j<a.length-1; j++) {

One of the random number generators in Java extract the higher-order bits of the random number in order to get a longer period.
I'm not sure if I understand how this is done. Suppose that the random number r = 0000 1100 1000 1101. If we extract the 16 most significant bits from r; is the new number r = 0000 1100 or r = 0000 1100 0000 0000?

I am having an array of strings and i want to find out whether these strings contained in the array contain a similar character or not.For example i am having following strings in the array of string:
aadafbd

sdfgyub
fhjgbjhjd
my program should provide following result: 3 because i have 3 characters which are similar in all the strings of the array(f,b,d).

I can sort strings in a collection by uppercase and then lowercase though I was wondering if there is any way of doing it in reverse, sorting by lowercase then by uppercase.

I have been working on this assignment for a bit now. I seem to have most of the logic of it down, as far as I can tell, but I seem to have fallen into a bit of a brain lapse when it comes to invoking methods I've made in my main method. Here's the code:
package Module5;
import java.util.Scanner;
public class Exercise6Nine {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
System.out.println("Enter 10 numbers.");
double[] numbers = new double[10];
[Code] .....
My question is, in my main method, I have code in there to attempt to call my method "min" from below, and to use the result of the min's calculations and print them via my main. Only, I can't seem to properly invoke the method from my main method!
Also, if you could check over my min method and see if anything blatantly wrong is there and let me know, that would be great.
Looking over my question, and it seems there is no EDIT button, but I may as well put the assignment parameters here, since I asked for double checking on my method. Write a method that finds the smallest element in an array of double values using the following header:
public static double min( double[ ] array )
Write a test program that prompts the user to enter 10 numbers, invokes this method to return the minimum value, and displays the minimum value.

I'm trying to apply a subset problem without using O(n^2) complexity. I need to find the smallest possible sum between 2 sets of 2 numbers in a lists so n1 + n2 = n3 + n4 = sum.
I have found solutions that all involve having the sum first and just finding the two pairs which involves using a hash table and then taking each number and subtracting it off the sum and looking for possible combinations.
How to do it if nothing but the list of numbers is given. So no sum and no hint of the pairs.
I put this in the Java section because I'm doing it in Java and there seems to be no generic algorithm/programming Topic area.

I think the problem in this is that the variable max is initialised as 0. Afterwards it remains in the while loop only, so the output is always 0. I dont know how to bring the last max value out of loop and print it.
