(JAVA) write a program that store random number from 1 to 52 in a array

Create another array, store first four number and find the biggest one.

Run 10000 times to see the occurences of each.

After I get the biggest number, I need help for run it 10000 times and find the occurences, please help

out put will be like this (should be increasing order)

Number: 4 Times:2

Number:5 Times:3

until 52 Number 52 Times 6XXX

import java.util.Arrays;

import java.util.Random;

public class RandomArray {

public static void main(String[] args) {

// creating Random class object to generate random numbers

Random r=new Random();

// creating two arrays

int arr[]=new int[52];

int arr2[]=new int[4];

// initialize first array with 1 to 52 random generated numbers

for(int i=0;i<52;i++)

arr[i]=r.nextInt(52-1)+1;

System.out.println("First four elements which are stored in another array are: ");

for(int i=0;i<4;i++) // storing first four numbers to second array

{

arr2[i]=arr[i];

System.out.print(arr2[i]+" ");

}

int max=arr2[0];

for(int i=1;i<4;i++)

{

// finding biggest number in second array

if(arr2[i]>max)

max=arr2[i];

}

System.out.println(" Biggest number is: "+max);

Explanation / Answer

import java.util.Arrays;

import java.util.Random;

public class RandomArray {

public static void printOccurences(int arr[], int index){
Random r=new Random();
int max=arr[index];
int ar2[]=new int[52];
for(int i=0;i<10000;i++){
int num=r.nextInt(52-1)+1;
ar2[num-1]++; //increasing on number index
}
for(int i=1;i<=52;i++){ //loop to print the occurences in increasing order
if(i==arr[0]){
System.out.println(arr[0]+" "+ar2[arr[0]-1]);
}
else if(i==arr[1]){
System.out.println(arr[1]+" "+ar2[arr[1]-1]);
}
else if(i==arr[2]){
System.out.println(arr[2]+" "+ar2[arr[2]-1]);
}
else if(i==arr[3]){
System.out.println(arr[3]+" "+ar2[arr[3]-1]);
}
}
}
public static void main(String[] args) {

// creating Random class object to generate random numbers

Random r=new Random();

// creating two arrays

int arr[]=new int[52];

int arr2[]=new int[4];

// initialize first array with 1 to 52 random generated numbers

for(int i=0;i<52;i++)

arr[i]=r.nextInt(52-1)+1;

System.out.println("First four elements which are stored in another array are: ");

for(int i=0;i<4;i++) // storing first four numbers to second array

{

arr2[i]=arr[i];

System.out.print(arr2[i]+" ");

}

int max=arr2[0];
int index=-1;

for(int i=1;i<4;i++)

{

// finding biggest number in second array

if(arr2[i]>max){
max=arr2[i];
index=i;
}

}

System.out.println(" Biggest number is: "+max);
//print occurences of 4 numbers
printOccurences(arr2, index);
}

}
