how do you write the code for multipliying 2 double arrays to be in a 3rd double array? here is my code:
package employeepay;
/** * * @author Owner */ public class Main {
/** * @param args the command line arguments */
public static void main(String[] args) { double[] values; values = getArray(); for (double num : values) System.out.print(num + " "); double[] values1; values1 = getArray1(); for (double num : values1) System.out.print(num + " "); double[] values2; values2 = getArray2(); for (double num : values2) System.out.print(num + " "); } /** getArray method @return A reference to an array of doubles. */ public static double[] getArray() { double[] array = { 1.2, 2.3, 4.5, 6.7, 8.9 }; return array; } /** getArray1 method @return A reference to an array of doubles. */ public static double[] getArray1() { double[] array1 = { 1.1, 2.2, 3.3, 4.4, 5.5 }; return array1; } /** getArray2 method @return A reference to an array of doubles. */ public static double[] getArray2(double[]array, double[]array1) { double[]array2 = (array[index] * array1[index]); return array2; } } the lines with double asterisks in front and back are the error lines thank you.

Hi Friend,
We have modified your code:
public class MultiplyTwoArrays{
public static void main(String[] args) {
double[] values = getArray();
for (double num : values)
System.out.println(num + " ");
System.out.println();
double[] values1 = getArray1();
for (double num : values1)
System.out.println(num + " ");
System.out.println();
double[] values2 = getArray2(values,values1);
for (double num : values2)
System.out.println(num + " ");
}
public static double[] getArray() {
double[] array = { 1, 2, 4, 6, 8 };
return array; }
public static double[] getArray1() {
double[] array1 = { 1, 2, 3, 4, 5 };
return array1;
}
public static double[] getArray2(double[]array, double[]array1) {
double[]array2=new double[array.length] ;
for(int i=0;i<array2.length;i++){
array2[i] = array[i] * array1[i];
}
return array2;
}
}
You can use simple code also:
public class MultiplyTwoArrays{
public static void main(String[] args) {
double[] array1 = { 1.2, 2.3, 4.5, 6.7, 8.9};
double[] array2 = { 1.1, 2.2, 3.3, 4.4, 5.5};
double []array=new double[array1.length];
for(int i=0;i<array.length;i++){
array[i]=array1[i]*array2[i];
}
for(int i=0;i<array.length;i++){
System.out.println(array[i]);
}
}
}
Thanks
