Printing Highest And Lowest Of Three Numbers Using Java
Feb 23, 2014
The class HighLow below asks for three integers and prints the highest and lowest of them on screen. Your task is to write the missing methods high and low, which receives the integers user inputs as parameters and return the highest and lowest integers respectively.
import java.util.Scanner;
public class HighLow {
public static void main(String[] args) {
int number1, number 2, number 3, high, low;
Scanner reader = new Scanner(System.in);

Java program takes positive int from user and determine if prime. Next the program finds next highest or next lowest prime number.

1.Write a JAVA program that will input 10 scores and output the Highest and Lowest score.
2.Write a JAVA program that will input the base and power and display the result: Example: Base is 4 Power is 2 the answer is 16 (Note: Math.pow( ) method is not allowed)
3.Write a JAVA program that will input an integer number, and then will output the sum of all inputted numbers. The program will stop in accepting inputs if the user entered 0.

In this project each individual will create a data analysis program that will at a minimum,
1) read data in from a text file,
2) sort data in some way,
3) search the data in some way,
4) perform at least three mathematical manipulations of the data,
5) display results of the data analysis in numeric/textual form, and
6) display graphs of the data. In addition,
7) your program should handle invalid input appropriately and
8) your program should use some "new" feature that you have not been taught explicitly in class.
(Note: this is to give you practice learning new material on your own - a critical skill of today's programmer.) If you do not have a specific plan in mind for your project, below is a specific project that meets all of the qualifications as long as 7) and 8) are addressed in the implementation.
Everything is done except I need to call my methods in my GradeTester.
GradeBook:
/**
*This class creates an array called scores.
*This class determines the length of the array scores and determines the last grade in the array scores.
*This class sorts the array using a bubble sort, and searches the array.
*This class calculates the mean, standard deviation, and the median of the grades in the array scores.
*Once the grades in the array is sorted, the class then calculates the highest and lowest grades in the array.
*/
public class GradeBook {
public final int MAXARRAY_SZ = 20;
double [] scores = new double [MAXARRAY_SZ];
int lastGrade = 0;
double mean = 0;

I'm very new to Java and ran into a problem. My results are not in order and I'm not sure what I'm doing wrong.
My results come out like this instead of being in order from lowest to highest: "77 99 44 55 22 88 11 0 66 33"
Here's what I have:
class ArrayIns {
private long[] a; // ref to array a
private int nElems; // number of data items
//--------------------------------------------------------------
public ArrayIns(int max) // constructor
{
a = new long[max]; // create the array
nElems = 0; // no items yet

Write a program that promts a professor to input grades for five different courses for 10 students. Prompt the professor to enter only A,B,C,D, or F for grades(A is the highest grade, F fail). use variables for student number(1 through 10) and grade numbers(1 through 5). create a menu for Search. if the user select search it will prompt a letter correspond to grade. display all student with selected grade. if the user just enter nothing, display all student with their grade sorted from highest to lowest.

I am not getting the result I am looking for, but I'm sure I'm on the right track. I have an array, names + times of marathon runners, and should end up with a program that displays the slowest runner, and the next-slowest runner.
Currently, I get this:
The lowest time is 273.
The lowest time is 243.
Changing names.length to times.length changes nothing.
for (i = 1;... ) changes nothing.
The displayed number should currently only be 243. Why is it displaying 273 first, and at all?
The code:
class Marathon {
public static void main (String[] arguments) {
String[] names = {"Elena", "Thomas", "Hamilton", "Suzie", "Phil", "Matt", "Alex", "Emma", "John", "James", "Jane", "Emily", "Daniel", "Neda", "Aaron", "Kate"};
int[] times = {341, 273, 278, 329, 445, 402, 388, 275, 243, 334, 412, 393, 299, 343, 317, 265};
int min = times [0];
for (int i = 0; i < times.length; i++) {
if (times[i] < min){
min = times[i];
System.out.println("The lowest time is " + min +".");
}

so for class I have an assignment that involves printing distinct numbers. the assignment is as follows: Write a program that reads in ten numbers and displays the number of distinct numbers and the distinct numbers separated by exactly on space. Here is what the input and the output are supposed to look like:
Input: Enter Ten Numbers: 1 2 3 2 1 6 3 4 5 2
Output: The Number of distinct numbers is 6
The distinct numbers are: 1 2 3 6 4 5
So far I have the entire code but right now it only prints out the distinct numbers, not how many distinct numbers there are. what that part of the code would look like?Here is my current code:
public class exer75 {
public static void main(String[] args) {
java.util.Scanner input = new java.util.Scanner(System.in); //create scanner system
System.out.println("");
System.out.print("Enter Ten Numbers: "); //prompt the user to enter 10 numbers
int[] values = new int[10]; //create an array to hold the numbers
[code]...

The assignment is to make a program that prints the number of prime numbers in a range. This is what i have so far. The output is a list of 2s. I created the for loop to cycle through the range of 17-53 and nested a while loop within to test each incident of the for loop to check for divisors starting with 2 until the modulus result is 0 resulting in a false for being a prime number. Then the loop should increment to the next i value. The last part is an if statement that i had intended to add counters to the k variable that would keep track of the number of prime numbers.
boolean isPrime = true;
int j = 2;
int k = 1;
for (int i = 17; i <= 53; i++){
{
while (i % j == 0){
isPrime = false;

I'm trying to find the int with the lowest value, and I only know how to set it up like this:
Let's say x1 is the lowest.
int x1, x2, x3, x4;
if (x1 < x2 && x1 < x3 && x1 < x4) System.put.println("x1 is the lowest value out of those 4");
Is there a way to shorten this at all? (It's alright if there isn't, just looking for shortcuts)

So I have this code to calculate the lowest value of an array:
public class Exercise1 {
public static void main(String[] args) {
int[] theArray = {1/*/,2,3,4,5,6,7,8,9,10/*/};
int result = Exercise1.min(theArray);
System.out.println("The minimum value is: " +result);

and I need to write an exception class that should be thrown if the array does not hold any elements.

I have to find the average, highest, and lowest numbers in an array. I already have the average and highest, and I thought I could find the lowest number the same way I found the highest, but it's not working. It just keeps coming out to 0. I've tried out different ways, but I want to see if there are better ways than doing MAX_VALUE for the lowest, then looping it through.
import java.util.Scanner;
public class Test_Scores {
public static void main(String[] args) {

If this method returns the lowest score, how do I return the 2 lowest scores.
For example If I input 1, 2, 3, 4, 5 this code will return 1.
How do i return the two lowest scores, for example if I input 1, 2, 3, 4, 5, I want to return 1, 2
public double getLowestScore() {
smallest = testScores[0];
double sum = 0.0;
double total = 0.0;
double Average = 0.0;
