Constructor for array of variable size

Question

I want to code a constructor for an array of size x with x being a parameter speciified in main().
My class:

public class CharA
{
  private char[] stack;
  private int n = 0;

  public void CharA (int max)
  {
    this.stack = new char[max];
    this.n = max;
  }

My main():

public class CharTest
{
  public static void main (String args)
  {
    CharA stack1 = new CharA(100);
  }
}

The error:

CharTest.java:5: cannot find symbol
symbol  : constructor CharA(int)
location: class CharA
    CharA stack1 = new CharA(100);
                   ^

There are several examples here where the same thing is done with an int array. Why doesn't it work for this char array?

remove void in your "constructor":

public CharA (int max) {
  // ...
}

Replace public void CharA (int max) with public CharA (int max), because constructors don't have a return type.

The constructor method should not have a return type in its definition:

public CharA(int max) {...}
