Find Both Largest And Smallest Of Several Integers
Apr 9, 2015
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 ;
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;
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 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;
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;
Write a function that accepts an array of non-negative integers and returns the second largest integer in the array.
Return -1 if there is no second largest.
The signature of the function is int f(int[ ] a)
Examples:
if the input array isreturn{1, 2, 3, 4}3{{4, 1, 2, 3}}3{1, 1, 2, 2}1{1, 1}-1{1}-1{}-1
In the signature what I understood is, I should write my function with the given signature,
The return type is "int"
method name is "f"
parameter is "a" right ?
Writing my doubts beside the particular line in the code
public static void main() // In the answer why they didn't use the class ?
In main method why they didn't use parameters ?(String[] args)
{ a1(new int[]{1, 2, 3, 4}); // what is "a1" here is it array name ? this line initializing the array ? a1(new int[]{4, 1, 2, 3}); a1(new int[]{1, 1, 2, 2}); a1(new int[]{1, 1}); a1(new int[]{1}); a1(new int[]{}); }
static int a1(int[] a) // what is "a" here parameter ? and "a1" is method name ? why they used the array name and method name same ?
{ int max1 = -1; int max2 = -1; for (int i=0; i<a.length; i++)
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;
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 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]) {
I'm required to create a program that finds the minimum value in an Array of integers.
Here is my approach :
public class Person { public static void main(String [ ] args){ int theArray[]=new int [10]; int result = 0; for (int i:theArray){ if (i < Integer.MAX_VALUE)
[Code]...
I can't really progress from this position. I keep getting told to change the return type to int on main method, then when i do it says change it to void..
I wrote this simple piece of code to find the number in the given array of Integers. The program works fine although it shows a couple of errors when i modify it a little bit.
public class DemoLabel{ public static void main(String [] args){ int[][] arrofInts={ {32,45,67,87}, {23,44,55,66}, {12,47,87,56}, {23,44,12,78}
[Code] .....
In the disp() method,Suppose i only want to pass two arguments i.e disp(i,j) given that searchFor variable is visible in the entire class but when i use disp(i,j) i get the following error
DemoLabel.java:38: error: cannot find symbol System.out.println("The number "+searchFor+" is at the location"+i+" , "+j); ^ symbol: variable searchFor location: class DemoLabel
So i decided to declare the
int searchFor as public int searchFor
But the compiler threw another error saying that it was a Illegal start of expression
Also,when i add a SOP line after the label search: it shows the error
In attempting to find the greatest common divisor (gcd) of two integers, n1 and n2, whereas k is a possible gcd and gcd is initialized to 1, the following code has been entered:
for (int k = 2; k <= n1 && k <= n2; k++) { if ( n1 % 2 == 0 && n2 % 2 == 0) gcd= k; }
When asked to change the previous line of code to this:
for (int k = 2; k <= n1 / 2 && k < n2 / 2; k++){
the questions states this revision is wrong and to find the reason.....well, I've changed it, entered "3" (per the answer key) for n1 and n2....
now I can see logically where k (2 in this example) is not <= n1/2, which is 3/2 or 1, since we're dealing w/integers, yet when I compile and run, my answer is indeed, gcd = 1. However, since this is a Boolean expression where && is being used, since the first portion evaluates to "false", the 2nd portion isn't executed and thus my result of 1?...... loops are throwing me for one, for sure....
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.
I've created a getMin method to return the smallest value in a queue. However, I'm having trouble calling the method in my main.
/** * Main method. * * @param args * the command line arguments; unused here */ public static void main(String[] args) { SimpleReader in = new SimpleReader1L(); SimpleWriter out = new SimpleWriter1L(); Queue<Integer> testQueue = new Queue1L<Integer>();
