How to determine if a variable in a program references a specific object?

To determine if a variable references a specific object in Java and Android, you can use the == operator, which compares references (memory addresses). If variable == object returns true, the variable references that object.

Example:

Object obj = new Object();
Object var = obj;

if (var == obj) {
    System.out.println("Variable var references object obj");
}

You can also use the equals() method, but it compares object content, not references. For reference comparison, == is appropriate.
