Display Largest And Smallest Numbers In A Series Of 10 Inputs
Apr 15, 2014
I have to get the user to enter in 10 numbers and with those 10 numbers I have to find the total, average, smallest, largest numbers in the set the user inputs. I have the total and average already figured out but how would you go about trying to find the largest and smallest numbers within this set of code.
import java.util.*;
public class testhw7
{
public static void main (String [] args) {
Scannernumberin = new Scanner (System.in);
doublevalue[];
doubletotal;
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. */ import java.awt.Graphics; import javax.swing.JApplet; import javax.swing.JOptionPane;
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 want to reverse grades that i have put using JOptionPane from largest to smallest and the corresponding names..
import javax.swing.*; import java.util.Arrays; public class ArrayUtils { public static void main (String[]args){ String length = JOptionPane.showInputDialog("Number of students");
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];
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();
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. */
import java.util.Scanner; import java.util.Random; public class LNFI_2DArray { public static void main(String[] args) { int guess; int[] array = new int[4];

I just had this code working, then all of a sudden i was hit with a 'keyboard leak' error code.
A java program to print 10 random numbers between 512 and 1024 and then finds the smallest and biggest numbers from the list using only one loop
class BSLab4d { public static void main (String[] args){ int[] nums = new int[10]; int largest = nums[0]; int x = 0; int smallest = nums[0]; int y = 0;
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.
My project is writing a program that generates a series of numbers to appear like a social security number (XXX-XX-XXXX). My code runs.. But any number below 10 it just shows one number (XXX-X-XXXX). What do I need to enter in to my code so that if the number is <10 it will show (00,01,02,03....)?
Java Code:
import java.util.Random; public class IDnumber { public static void main (String[] args) { Random generator = new Random() int num1 = (generator.nextInt(7) + 1) * 100 + (generator.nextInt(8) * 10) + generator.nextInt(8); int num2 = generator.nextInt(74); int num3 = generator.nextInt(10000); String IDnumber = num1 + "-" + num2 + "-" + num3; System.out.println(IDnumber); } } mh_sh_highlight_all('java');
write a java program to check divisibility of a series of numbers that a user inputs the starting and ending numbers and also the number to check divisibility with.
The problem I am having is it only checks the first number and doesn't check the rest.
import java.util.Scanner; public class MyMidTermAssignment { public static void main(String[] args) { int numberInputBeginning,numberInputEnding,divisibleByNumber; System.out.println("Enter first number of series");
So basically, I've been trying to create a for loop that asks the user for a number between 1 and 30, then calculates the total of the series of numbers. For example, if 15 is entered, the calculation should be 1/15+2/14+3/13+...15/1 which would equal approximately 38.1. The problem I'm having is that the code doesn't loop whenever I type a number for some reason, which results in a very incorrect calculation. Here is my code so far:
import java.util.Scanner; public class HmwLoop { public static void main(String[] args) { double sum = 0; for (double num1 = 1, num2 = 30; num1 <= 30 && num2 >= 1; num1++, num2--)
I need to find the largest value in a scanned file.I've gotten the count, sum, average, evens, and odds myself.The code above the while loop is not mine and my professor said I may no edit it or other wise mess with it. I also may not use arrays.Also I've realized that the largest/smallest are recording the value of count. I've tried the following:
Scanner infile = new Scanner ( new FileReader(args[0]) ); int count=0,sum=0, largest=Integer.MIN_VALUE,smallest=Integer.MAX_VALUE, evens=0, odds=0; double average=0.0;
tfrreee i want to display given series in ascending order in java prog here is an error : E:Javajdkin>java ascend 505671Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 7 at ascend.main(ascend.java:9)
Java Code:
class ascend { public static void main (String args[]) { int s[]={ 50,71,81,21,7}; int i; for(i=0;i<=s.length;i++)
import java.util.Scanner; public class AvgLrgSml{ public static void main(String[]args){ System.out.print("Hello there. Please enter any three numbers."); Scanner keyboard = new Scanner(System.in); double num1 = keyboard.nextDouble(); double num2 = keyboard.nextDouble();
I have problem with sorting my numbers from smallest to biggest and i need to not have repeating numbers, I am stuck. I tried using Arrays.sorts(lottery) but didn't work. and i don't know to but make the numbers not repeat in the same line.
package lottonumbers;
public class LottoNumbers { public static void main(String[] args) { int[] lottery = new int[6]; for (int numoftimes=0;numoftimes<5;numoftimes++){
I am trying to find 3 largest numbers in an array using a single For loop but my following code is still showing randomly sorted numbers.
public class largest3 { static int m, n, o; static int array[] = new int[100]; public static void main(String[] args) { for (int i = 0; i < 10; i++) { array[i] = (int) (Math.random() * 100);
I am trying to write a code that asks the user to input ten numbers and then finds and displays the smallest number out of the ones given. I am supposed to implement arrays into the program to do this. But the problem I have run into is that when I compile the code in jgrasp, I am given several error messages and I am not quite sure what I have done wrong. I'm assuming it is either a syntax or a logical error on my part but reading over the code I do not understand what is causing these errors.
This is the most current draft of my code:
import java.util.Scanner; public class Exercise7_9 { public static void main(String[] args) { double[] numbers = new double[10]; //Enter ten double numbers: Scanner(System.in) java.util.Scanner input = new java.util.Scanner(System.in); System.out.println("Please enter ten numbers: ");
[Code] ....
/* Sample Run: Enter ten numbers: 1.9, 2.5, 3.7, 2, 1.5, 6, 3, 4, 5, 2 */
And these are the exact error messages:
----jGRASP exec: javac -g Exercise7_9.java Exercise7_9.java:35: error: '.class' expected if (double m > list[i]) { ^ Exercise7_9.java:35: error: illegal start of expression if (double m > list[i]) {
So I have a program for a project that permutes a random series of numbers using Java's Rand function. Basically I use a seed and a number of items I want in the arrangement of numbers, and the program makes a permutation with no two numbers being repeated. Only arrays can be applied to it, so I've been hard at work finding a solution.
Here's the code so far:
public static int permutation[]; public static void permute(int numOfItems, int seed){ permutation=new int[numItems]; Random rand = new Random(seed); permutation[0]=rand.nextInt(numItems-1);
[Code] ......
So basically I'm wanting the program to make a randomized list of numbers from the number of items I pass to the Permute method with no duplicates. I'm having some level of success with what I have written, as it gives me a randomized list when printing the output, but for some reason the first for statement in code never terminates fully, but instead runs indefinitely when generating the last integer.
For example, if I want to put 10 with a seed of 0 into it and make a list from 0-9, it will print 74283510, which is only 8 different integers. permutation[0] is manually set at the beginning of the method, which accounts for one more, but that's still only a list of 9, so I'm just wondering why the last integer is not being generated and why the program keeps looping and not terminating? I'm know for sure it's something I'm overlooking.
I'm just not noticing why it won't display the answer. I'm trying to solve this book problem......
"Write a for loop that calculates the total of the follower series of numbers:
1/30 + 2/29 + 3/28......+30/1"
Here is what I have..
public static void main(String[] args) { double total = 0; for (double a = 1, b = 30; b < 1; a++, b--) { total += (a / b); } System.out.println(total); } }
When launched, the output is 0.0. I tried changing the variables a and b to doubles but didn't change anything...

can count the numbers from 0-9 if the user puted but if it is 10 it doesnt count it , and i need to write all the numbers to have that option. . . . Is there an easy way that includes all the numbers? like if(word.equals(number)){<<<???? (numbers) i know htat doesnt work but is there anything similar ?? ??
countNumbers++; } System.out.println("Type Something , , , and to end the the termination type STOP"); word=input.nextLine(); count++; } System.out.println("You wrote "+count+" lines wich from those lines "+countNumbers+" were numbers and the programe terminated "); } }
Develop an algorithm for a Java program that takes as input a single letter and displays the corresponding digit on the telephone. The letters and digits on a telephone are grouped this way:
The screen dialog might look like this: Enter a single letter, and I will tell you what the corresponding digit is on the telephone. R The digit 7 corresponds to the letter R on the telephone.
The program should display a message indicating that there is no matching digit for any non-alphabetic character entered by the user. Also, the application should recognize only uppercase letters. If a user enters a lowercase letter, the program should display an error message. Prompt the user with an informative message for the input value as shown above.
The application should include the input letter as part of the output.
Write the algorithm to solve this problem including steps for prompting the user, getting input from the keyboard, and displaying the results.
Write the Java program that you designed, using your algorithm as a guide. Use your algorithm as comments in the body of the main method.
Use proper indentation, and meaningful identifiers throughout the code.
I've just written a program that generates 100 numbers that range from 0 ~ 25 using arrays, the program calls another method that sorts the even numbers into a separate array and returns the array. I need it to display both arrays, however, when I run my program, the numbers of both arrays are mixed together, and I'm not sure how to separate them.
[ public class Array1 { public static void main(String[] args) { int array [ ] = new int[100]; for (int i = 0; i < array.length; i++) { array[i] = (int) (Math.random() * 26);
