Find Largest Num Of Numbers In Scanned File

Jul 10, 2014

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;

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 ;

[Code] ....

Largest Of Input Numbers?

Nov 5, 2014

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.

import java.util.Scanner;

/**

Program To Find If Numbers Are Consecutive Or Not

Feb 23, 2014

im trying to do a program to find if numbers are consecutive or not! if they are consecutive i need a true as a return and a false when they are not... i did this program and im sure i did something wrong because i keep only true returns ..

Example: (3,5,7) (1,2,2) (7,7,9) should return a false!
Java Code: import java.util.*;
public class Consecutive{
public static void main (String [] args){
Scanner console= new Scanner(System.in);
System.out.println("Enter three numbers");
String numbers = console.nextLine();
System.out.println( "The numbers (" + numbers + ") is '" + consecutive( numbers ) + "'" );
}//end of main

Find Arithmetic Mean Of The Numbers Stored In Array

Feb 23, 2014

The program below is intended to find the arithmetic mean of the numbers stored in the array q in two ways: once by storing the numbers in an ArrayList d, where you allow all the necessary conversions to be performed automatically; and once by storing them in an ArrayList e, where you perform all the conversions by hand. Complete the program.

Here is what I have so far:

double[] q = { 0.5, 2.4, 7.4, 2.8, -6.2 };
ArrayList<Double> d = new ArrayList<Double>();
ArrayList<Double> e = new ArrayList<Double>();
for ( double x : q ) {
d.add( x );
e.add ( new Double ( x ) );

[Code] .....

Why does it still show "a / d.size?" I thought I fixed that. Whatever, it's supposed to be "dTotal / d.size()", etc.

Logic To Find Adjacency Of Numbers 0 And 1 In Array

Oct 3, 2013

I should mention here that number of elements can be from 1....10'000. And it has to be done as O(N)

I attempted at the problem like so :

public static int adjacencies(int[] A) {
int count = 0;
boolean found = false;
for(int i = 0; i < A.length-1; i++) {
if (A[i] == A[i+1]) {

[Code] .....

To me it looks right and it seems to work.

Sieve Code To Find Prime Numbers

Jan 16, 2015

I am doing a sieve code to find prime numbers.

public static void main(String[] args)
{
Scanner scanner = new Scanner(System.in);
System.out.println(" Enter the maximum number ");
int maxNumber = scanner.nextInt();
int[]numberList = createList (maxNumber);

[code]....

I have a problem with the output. It only get as far as marking the multiples of 2. It does not mark the multiples of 3 and so on.Example output: If the range is from 2 to 15 the output is :2, 3, 0, 5, 0, 7, 0, 9, 0, 11, 0, 13, 0, 15 note: 0 means its marked.As you can see it only marks multiples of 2 but it does not mark multiples of 3 above. I think the problem lies in the for loop inside my main method, because the index does not increment.

Array Is A Set Of Numbers In Triangle - Find Maximum Path

Aug 12, 2014

If you aren't familiar with the euler problem 67, you are given an array that is a set of numbers in a triangle. Like this

3
7 4
2 4 6
8 5 9 3

and you have to find the maximum path, which for this one is

(3)
(7) 4
2 (4) 6
8 5 (9) 3

I have solved this problem iteratively with the code below

depth = depth-2;
while (depth >=0) {
for (int j = 0; j <= depth; j++) {
values[depth][j] += Math.max(values[depth+1][j], values[depth+1][j+1]);
}
depth -= 1;
}

depth is a variable for the row in the triangle. My problem is that i need the solution to be recursive and i am having trouble doing this. So far i have

public static int findMax(int[][] array,int depth) {
if (depth==0)
return array[0][0];
else if
}

User To Input 10 Numbers - Find Smallest Element In Array

Dec 2, 2014

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]) {

Prime Numbers - Find N From List That Is Not Crossed And Cross Out All Its Multiples

Jun 20, 2014

the prime numbers from 1 to 2500 can be obtained as follows. From a list of the numbers of 1 to 2500,cross out al multiples of 2 (but not 2 itself). Then, find the next number (n, say) that is not crossed out and cross out all multiples of n (but not including n).

Repeat this last step provided that n has not exceeded 50 (the square root of 2500). The numbers remaining in the list (except 1) are prime. Write a program which uses this method to print all primes from 1 to 2500. Store your output in a file called primes.out.

Servlets :: File Is Located In Root Directory Of Project But System Cannot Find File Specified

My file is located in the root directory of the project.

And here is how I indicate the path to it:

String filePath = "default.jpg";
InputStream inputStream = new FileInputStream(new File(filePath));

If I put the file in the Eclipse folder, it works... But I need it to work if I put it in my project's root folder.
