Float Variable: A float variable is another data type in Java that represents floating-point numbers but with single precision, meaning it has less range and precision compared to a double variable.
Integer Variable: An integer variable is a data type in Java that stores whole numbers without any decimal points. It has limited range but provides precise calculations for whole number values.
Long Variable: A long variable is also an integer data type in Java but with a larger range than the int data type. It can hold larger whole number values, useful when dealing with big numbers or large computations.
