I have a java code and it work with success !
//data
double[] query = {0.65,0.78,0.21,0.29,0.58};
but now i want user put the strings manual like this :
println("insert the values like that {xx,xx,xx,xx,xx} ")
i think must use scanner but i don't know how ?
If you want to get double numbers from user, use nextDouble() method, like this:
Creating a Scanner object:
Scanner scan = new Scanner(System.in);
Reading inputted numers from user:
Double insertedDouble = scan.nextDouble();
Double insertedDouble2 = scan.nextDouble();
Making an array of inputted numers:
double[] array = {insertedDouble, insertedDouble2};
If input is to be taken in from user input, use scanner this way:
Scanner scanner = new Scanner(System.in);
Make sure to intialize array:
private double[] array = new double[10];
Prompt user for input:
System.out.println("Please enter double value: ");
array[0] = scanner.nextDouble(); //gets input from user using scanner, store in first index of array
Print:
System.out.println(array[0]);
It's straight forward to use scanner try this:
import java.util.Scanner;
public class Main {
public static void main(String[] arguments) {
// Set the number of values
int values = 5;
// Create an empty array for values
double query[] = new double[values];
// Create scanner object to use
Scanner input = new Scanner(System.in);
// Parse Items for input
for(int i = 0; i < values; ++i) {
System.out.println("Please input value num in 0.0 format ");
query[i] = input.nextDouble();
}
// Print the values for success
for(int i = 0; i < values; ++i)
System.out.println(query[i]);
}
}
i++is good for the latter.
