The == and != operators in Java works differently for different kinds of values: for primitives, they check whether the two values represent the same meaning, but for objects they checks whether the values occupy the same location in memory. Therefore, given two objects x and y that hold the same data but have different places in memory, the Java expression x == y will be false. To check for semantic equality, the programmer must invoke a dedicated method, usually by writing an expression like x.equals(y).

In contrast, Python's == and != operators always check whether two values mean the same thing and ignore their locations in memory. If a Python programmer wants to compare memory locations, they must instead use the operators is and is not. For example, given the x and y from above, Python would interpret x == y as true, but x is y as false.

Sometimes the two kinds of operators effectively have the same meaning. For instance, the only way for two enumeration values to have the same meaning is if they have the same memory location. In such cases, it is considered good style to prefer is and is not over == and !=.

Finish the program by writing relational operators so that it correctly labels each of the claims as true or false.
