A variable must be declared before it is used.

A variable cannot be assigned a value after its declaration.

A variable can hold multiple values at once.

A variable name can start with a number.

aCar = new Car();

aCar = Car();

new Car();

Car aCar = new Car();

The while loop can only be used for integer values, while the do-while loop can handle all data types.

The do-while loop always executes at least once, while the while loop may not execute at all.

The do-while loop is faster than the while loop.

The while loop always executes at least once, while the do-while loop does not.
