{JAVA} How to create a method to find mode?

[creativename]

I need my code to create an array of 10 random integers, and then I need to use a new method to find the mode of those 10 integers.

 

My code so far is

 

 

 public class mode{public static void main(String args[]){int[] x;x = new int[10];System.out.print("Data Array: ");for(int count = 0; count<x.length; count++){x[count] = (int) (Math.random()*10);System.out.print(x[count] + " ");}}}

 

 

 

I'm not quite sure how to create a new method, or how to find mode.

What are y and z? 

 

Do you have to create it as a method or can it be in the same function? 

 

And does efficient matter?

Oh it seems those are the left over variables from my other assignment where I had to talley the array. Let me edit it out.

 

And the goal was to create a method that finds mode.

This could be your method: and then inside the brackets you would implement it, and then return either the index to the most common element, or the value of the most common element. 

int findMode(int[] array){ }

I don't have to do that "public void findMode" thing?

my bad

public static int findMode(int[] array){ }

my bad

public static int findMode(int[] array){ }

 

 

I got these errors

 

mode.java:12: error: illegal start of expression

public int findMode(int[] array);

^

mode.java:12: error: ';' expected

public int findMode(int[] array);

                   ^

mode.java:12: error: ';' expected

public int findMode(int[] array);

lose the semicolon

lose the semicolon

It gave even more errors lol

mode.java:12: error: illegal start of expression

public int findMode(int[] array)

                   ^

                               ^

mode.java:14: error: ';' expected

System.out.print(x.findMode)

                                     ^

4 errors

When I ran it,it seems to be missing a return statement?

Yes, you're going to need to write the findMode function, and end it with a return line that returns the max element.

Yes because it has an int return type. So you need to return an integer inside the function for things to compile.
