【问题描述】：
我正在开发一个统计分析程序，该程序将计算一些东西。我不需要构建方面的帮助，因为我了解需要如何完成。我遇到的问题与我构建的数组有关。当我尝试显示数据时，我得到了一个非常奇怪的输出。下面是输出
public class Project_StatisticalAnalysis {
public static void main(String[] args){
System.out.println("Good Day,");
System.out.println();
System.out.println("This program can run statistical analysis on integer");
System.out.println("data up to 100 values; it can calculate the mean,");
System.out.println("median, mode, variance and standard deviation.");
System.out.println("");
Scanner input = new Scanner(System.in);
System.out.println("Please enter the number of values you will be calculating: ");
int values = input.nextInt();
//Create Array
final int numArray = values;
double [] numberValues = new double[numArray];
double sum = 0;
for (int i = 0; i < numArray; i++){
System.out.println("Please enter a number:");
numberValues[i] = input.nextDouble();
sum += numberValues[i];
}
//Call to Methods:
displayNumbers(numberValues, values);
sort(numberValues);
mean(numberValues);
median(numberValues);
mode(numberValues);
standardDeviation(numberValues);
variance(numberValues);
}
public static void displayNumbers(double numberValues[], double values) {
System.out.println("You entered:");
System.out.println();
int count = 0;
for (int i = 0; i <values; i++){
System.out.print(numberValues+" ");
count++;
if (count == 10) {
System.out.println();
count = 0;
}}
}
public static void sort(double numberValues[]){
}
public static void mean(double numberValues[]){
}
public static void median(double numberValues[]){
}
public static void mode(double numberValues[]){
}
public static void standardDeviation(double numberValues[]){
}
public static void variance(double numberValues[]){
}
}
输出是：
Good Day,
This program can run statistical analysis on integer
data up to 100 values; it can calculate the mean,
median, mode, variance and standard deviation.
