Char cannot be dereferenced Issue with getNumericValue()

I'm trying to do a pyramid like:

a
bc
def
ghij 
klmno

but it gives me the error: Char cannot be dereferenced

I have a very easy code:

public class PiramideLetras {

    public static void main (String args[]) {
        char cha = 'A';
        for (int i=0;i<5;i++){
            for(int y=i;y>=0;y--){
                    System.out.print(cha);
                    int b = cha.getNumericValue();
                    }
            System.out.println("");}
    }
}

Why I get this error?

Char.getNumericValue is a static method which takes the value as an argument. So you want:

int b = Char.getNumericValue(cha);

You can't use primitive types as the target of any kind of method call.
