import java.net.InetAddress; public class Printer { private String name; private InetAddress address; public Printer(String name, InetAddress address) { this.name = name; this.address = address; } public String getName() { return name; } public void setName(String name) { this.name = name; } public InetAddress getAddress() { return address; } public void setAddress(InetAddress address) { this.address = address; } @Override public boolean equals(Object o) { if (o instanceof Printer) { Printer printer = (Printer) o; if (printer.name.equals(this.name)) return true; } return false; } } |
This class represents an instance […]
