I am writing an order list program in Java and there is a compareTo() method requirement, instructions below. Within this method I need to have 2 parameters evaluated - one is a String and the other is an integer. Ideally, I need both parameters to uniquely identify one "thing" from the other and "street" alone will not do that - also need "number" to make it a unique object. I am getting an error message from the compiler that states "The operator && is undefined for the argument type(s) int, boolean". My code is pasted below.

public class Property { private String street; private int number; private boolean occupied; public Property(String street, int number, boolean occupied) { this.street=street; this.number=number; this.occupied=occupied; } .................

public int compareTo(Property p) { return this.getStreet().compareToIgnoreCase(p.getStreet())&&this.getNumber()==(p.getNumber());

Below are the specific instruction for this section of the program.

Implement the Comparable interface and the compareTo() method for your Thing. compareTo() returns

• a negative number when the invoking object's search key is less than the parameter's search key
• 0 when the two search keys are equal
• a positive number when the invoking object's search key is greater than the parameter's search key
• For example, "ant".compareTo("bat") will return a negative number.
• Your compareTo() method must compare two Things.
• Note that the comparison of String attributes should be case insensitive. For example, MATH, math and Math must match each other.
