Thread: Object array with constructor

I have a class project that requires a Symbol array. The parameters are:

Symbol class with constructor and methods equals and toString and a TestDriver class that declares the Symbol array and main. Here's what I have:

public class Symbol {
private String inputSymbol; //Instance variable
 
    public Symbol(String sym){
        inputSymbol = sym;
    }
 
    public boolean equals(Symbol sym){
        return false;
    }
 
    public String toString(){
    }

public class TestSymbols {
 
public static void main(String[] args) throws IOException {
Symbol[] sym = new Symbol[100];
 
sym[0] = new Symbol("Katie");
String tempText = sym[0].toString();
System.out.println(sym[0]);
System.out.println(tempText);
 
System.exit(0); //end program
 
}
 
}

The print statements are always null. What am I doing wrong that I cannot populate/access sym? How do I add and read an element at sym [i]?

Thanks for your halp.
