Everyone,
To iterate through these collections when adding a class object as a
collection item, the answer was in some older postings in this group.
I followed the suggestion to Override the toString method within
MyOwnClass :
public String toString() {
return this.name + " Age : " + (this.age) ;
}
So when assigning who class objects as in this code
HashSet hs = new HashSet();
hs.add("LSU"); // Sring objects
hs.add("Tigers");
MyOwnClass moc1 = new MyOwnClass("Jeff", 55);
MyOwnClass moc2 = new MyOwnClass("Tom", 48);
hs.add(moc1);
hs.add(moc2);
Integer myInt1 = 100;
Integer myInt2 = 50;
Integer myInt3 = 25;
hs.add(myInt1); // Integer objects
hs.add(myInt2);
hs.add(myInt3);
the standard iteration worked
System.out.println("Contents of Hash Set");
System.out.println();
for (Iterator i = hs.iterator(); i.hasNext();) {
System.out.println(i.next());
}
Example output
50
Jeff Age : 55
100
Tom Age : 48
25
Tigers
LSU
To those posters from a few years ago, thank you.
Jeff
