public class IntegerVariable

extends Variable

This class defines an integer variable that has an integer value. It also defines a set of methods for dealing with integer variables:

• add(int intValue) -- Adds the value of the specified integer to the value of this integer and returns the sum as an integer value.
• add(int value1, int value2) -- Adds the values of the two specified integers and returns the sum as an integer value.
• and(int intValue) -- Performs a bitwise AND between the value of this integer and the specified integer value and returns the result as an integer.
• and(int value1, int value2) -- Performs a bitwise AND between the values of the provided integers and returns the result as an integer.
• assign(int intValue) -- Specifies the value to use for this integer variable from the provided integer value. This method does not return a value.
• assign(string stringValue, int defaultValue) -- Parses the provided string as an integer value and uses is as the value for this integer variable. If the string value cannot be converted to an integer, then the provided default value will be used.
• decrement() -- Decreases the value of this integer variable by one. The decrement is made internally and this method does not return a value.
• decrement(int amount) -- Decreases the value of this integer variable by the specified amount. The decrement is made internally and this method does not return a value.
• divide(int intValue) -- Divides the value of this integer variable by the value of the provided integer value and returns the quotient as an integer value.
• divide(int value1, int value2) -- Divides the value of the first integer by the value of the second and returns the quotient as an integer value.
• equals(int intValue) -- Determines whether the value of this integer variable is equal to the value of the provided integer variable. The result is returned as a Boolean variable.
• equals(int value1, int value2) -- Determines whether the two integer values are equal and returns the result as a Boolean variable.
• greaterThan(int intValue) -- Determines whether the value of this integer variable is greater than the value of the provided integer variable and returns the result as a Boolean variable.
• greaterThan(int value1, int value2) -- Determines whether the first integer value is greater than the second and returns the result as an integer variable.
• greaterThanOrEqualTo(int intValue) -- Determines whether the value of this integer variable is greater than or equal to the value of the provided integer variable and returns the result as a Boolean variable.
• greaterThanOrEqualTo(int value1, int value2) -- Determines whether the first integer value is greater than or equal to the second and returns the result as an integer variable.
• increment() -- Increases the value of this integer variable by one. The increment is made internally and this method does not return a value.
• increment(int amount) -- Increases the value of this integer variable by the specified amount. The increment is made internally and this method does not return a value.
• lessThan(int intValue) -- Determines whether the value of this integer variable is less than the value of the provided integer variable and returns the result as a Boolean variable.
• lessThan(int value1, int value2) -- Determines whether the first integer value is less than the second and returns the result as a Boolean variable.
• lessThanOrEqualTo(int intValue) -- Determines whether the value of this integer variable is less than or equal to the value of the provided integer variable and returns the result as a Boolean variable.
• lessThanorEqualTo(int value1, int value2) -- Determines whether the first integer value is less than or equal to the second and returns the result as a Boolean variable.
• multiply(int intValue) -- Multiplies the value of this integer variable by the value of the provided integer variable and returns the product as an integer variable.
• multiply(int value1, int value2) -- Multiplies the two provided values and returns their product as an integer value.
• not() -- Performs a bitwise NOT on this integer value and returns the result as an integer.
• not(int intValue) -- Performs a bitwise NOT on the provided integer value and returns the result as an integer.
• notEqual(int intValue) -- Determines whether the provided integer value does not match this integer and returns the result as a Boolean.
• notEqual(int value1, int value2) -- Determines whether the two provided integer values are different and returns the result as a Boolean.
• or(int intValue) -- Performs a bitwise OR between the value of this integer and the specified integer value and returns the result as an integer.
• or(int value1, int value2) -- Performs a bitwise OR between the values of the provided integers and returns the result as an integer.
• remainder(int intValue) -- Divides the value of this integer variable by the provided integer value and returns the remainder as an integer value.
• remainder(int value1, int value2) -- Divides the first integer value by the second and returns the remainder as an integer value.
• subtract(int intValue) -- Subtracts the the value of the provided integer variable from the value of this integer variable and returns the difference as an integer variable.
• subtract(int value1, int value2) -- Subtracts the first value from the second value and returns the difference as an integer variable.
