Java Random Number Array Error

Question

I've written a small Java app to generate arrays randomly, with random numbers. This class works properly:

Dice.java

import java.util.*;

public class Dice {
    private int i = 10;
    private int value = 0;
    private Random rnd = new Random();

    public void roll_dice() {
        int g = i;

        value = rnd.nextInt(g); // Here is not make a  single error.
        if ((value != 0) & (value <= 6)) {
            System.out.println("Number is :" + value);
        } else {
            System.out.println(" Error number should be between 1 and 6. Try again");
        }
    }
}

When I go to compile this following class, however, I get the following error:

Error cannot find symbol - method nextInt(int)

Random.java

import java.util.*;

public class Random {
    private int[] number;
    private int g;
    private Random rnd = new Random();

    public void Bicbig(int amount) {
        g = amount;

        if ((amount >= 1) & (amount <= 100)) {

        } else {
            System.out.println("Please Enter Between 1 and 100. Please try again .");
        }
    }

    public void generate() {
        number = new int[g];

        int u = rnd.nextInt(g); // Error cannot find symbol - method nextInt(int)
    }
}

Why am I getting this exception? How can I fix it?

You shouldn't name your class as Random. It hides java.util.Random. Program will compile after renaming

You called your class Random, overriding java's Random class. Rename it.

The nextInt() method doesnt exist in your random class

You have a name clash between your Random function, and the one in java.util.

Remove import java.util.*; and refer to the Java library function as java.util.Random.
Rename your Random class.

In reality, I'd do both.

Change

private Random rnd = new Random() ;

to

private java.util.Random rnd = new java.util.Random();
