Java METHOD help, UEGENT***

[Nemeliza]

I am trying to create a method but am having difficulty, here is what i have:

This is the main.

public static void main(java.lang.String[] args) 
{
	
        for (int i = 0; i < 50; i++) {
        int rand = (int) Math.ceil(Math.random() * 100);
        num[i] = rand;
    }
    for (int i = 0; i < 50; i++) {
        System.out.println(num[i]);
    }
	
	calcMode.getMode(num);

System.out.println(calcMode);
    
}

This is the getMode method:

public static int getMode() {
	int j = 0;
	
int[] counters = new int[100];

//count the occurrence of each number

for (int i = 0; i < num.length; ++i){

  ++counters[num[i]]; //count the frequency of particular number

}


//find mode from range array

mode = 0;

for (int i = 0; i < counters.length; ++i){

  if (counters[i] > counters[mode]){

    mode = i; //new mode index

  }

}


//find if multiple modes

int maxNum = counters[mode];

for (j = 0; j < counters.length; ++j){

  if (counters[j] == maxNum){

    System.out.println("mode : " + j);

  }
  
}

    	return j;	

}

When i run it i amgetting this error:

The method getMode invoked for type int with arguments (int []) is not defined

HEEEEEEEEEEEEEEELP!

When you define getMode you are telling it to RETURN an int, not receive one.

So instead of:

public static int getMode() {

you should have

public static int getMode(int whatEverYouWantToCallTheIntegerYouPassIn) {

I'm not sure what the method is meant to do, but that is why it is not compiling.

Thaaaank you!

Appreciate it.

By the way - the Random() class is worth a look for generating random numbers.

e.g. rather than doing

int rand = (int) Math.ceil(Math.random() * 100);

you can do

int rand = (new Random()).nextInt(100);
