I have a custom object that has a single value of type int that I wanting to do processing on to keep this value in a set range. My question is this: Given the following class, can I set it's value with myObject = 0;
public class foo{
private int bar;
public foo(){
}
}
Instead of creating a method public void setBar()

First, define a class with any name 'SampleClass' and define a constructor method. The constructor will always have the same name as the class name and it does not have a return type. Constructors are used to instantiating variables of the class. Now, using the constructors we can assign values.
If we use the assignment operator to assign an object reference to another reference variable then it will point to the same address location of the old object and no new copy of the object will be created. Due to this any changes in the reference variable will be reflected in the original object.
Access and retrieval times are quite fast. To add the user-defined object into TreeSet, we need to implement a Comparable interface. An element that we want to add in TreeSet must be a comparable type. If we don't implement the Comparable interface then it will throw ClassCastException.
If you mean:
foo x = new foo();
x = 10; // This is meant to set x.bar
then no, you can't do that in Java. Good thing too, if you ask me... it would be horrible in terms of readability.
You also can't change it to allow:
foo x = 10;
as equivalent to:
foo x = new foo();
x.bar = 10; // Or x.setBar(10);
