I'm working on a simple java program that will create an array of 50 random numbers and display them, then will print what the biggest number is and where its' index would be. However, I keep getting an error that says "Constructor cannot be applied to given types". I know that this is an issue with the argument that the constructor asks for but I'm not sure how to fix it so I was hoping to get some advice.

For reference, here's the code I have so far. The issue is for the constructor being used on line 49.

class maxNumArray {
  
  //define variables to store the max number and its' index
    private static int max;
    private static int maxIndex = 0;
    private static int[] numArray;
    private static int arrayLength;
    private static int myArrayLength;

public void maxNumArray(int myArrayLength){
    //create an integer array with a length of 100
    arrayLength = myArrayLength;
    //return arrayLength;
}

  public static void makeArray(){
    //create a for loop to repeat for the length of the list
    numArray = new int [arrayLength];
    max = numArray[0];
    for (int i=0; i<numArray.length; i  ){
      //set index [i] to a random bumber between -50 and 50
      numArray[i] = (int)(Math.random() *102 (-51));
      //if the number at position [i] is greater than the current max number, set it to the max and change the index to match.
      if (numArray[i]>max){
        max = numArray[i];
        maxIndex = i;
      }
      //print out the array
      System.out.println(numArray[i]   " ");
    }
  }

  public static void maxValue(){ 
    //print out the max value and its' index within the array
    System.out.println("The highest value is "   max   " at an index of "   maxIndex);
  }
}

class Main{
  public static void main(String[] args) {
  maxNumArray myArray = new maxNumArray (100);
  myArray.makeArray();
  myArray.maxValue();
  
  }
}

You should always capitalize your class names, to distinguish between methods.

public void maxNumArray(int myArrayLength)

This appears to be an attempt at a constructor. Constructors have no return type as they cannot return any value. Remove void to make this a valid constructor.

public class MaxNumArray {

    public MaxNumArray(int arrayLength) {
        // do class initialization stuff here
    }

}
