Random number prob

Question

i am trying to create an array tht outputs random numbers...i keep getting one error which is in the for statement...can anyone help me weed this problem out?
import java.util.* ;
public class Arrays2{     
     // main(): application entry point     
     public static void main(String[] args) {
     final int N = 1;
     int x[] = new int[N];
     fillArray(x);
     System.out.println("int i:" + x);
public static void fillArray(int[] x) {
     for (int i = 0; i < 10; i++) {
     int x[i] = Math.random();     
}

Answer 1

C:\jexp>javac a2.java
a2.java:13: x is already defined in fillArray(int[])
            int x = Math.random();
                ^
a2.java:13: possible loss of precision
found   : double
required: int
            int x = Math.random();
                               ^
2 errorsThe first error points out that the variable "x" is sent into the "fillArray" method as an argument which makes it a local variable. You declared it again in the first/only statement inside the for loop.
About the second error: "Math.random" returns a double (see "random" method Math api). You are assigning this (double) value to an int which has less precision (no decimal places, smaller container). Try
import java.util.* ;
public class A2 {
    public static void main(String[] args) {
        final int N = 10;
        int range = 10;
        int x[] = new int[N];
        fillArray(x, range);
        for(int j = 0; j < x.length; j++)
            System.out.println("x[" + j + "] = " + x[j]);
    public static void fillArray(int[] x, int limit) {
        for (int i = 0; i < x.length; i++) {
            x[i] = (int)((limit+1) * Math.random());
}
