- public class IntegerComparer
- extends Comparer
A concrete class for comparing Number objects which contain values
that can be converted to an int.
-
equals(Object, Object)
- Returns true if the leftOperand is equal to the rightOperand.
-
getInstance()
- Returns a IntegerComparer object.
-
greaterThan(Object, Object)
- Returns true if the leftOperand is greater than the rightOperand.
-
lessThan(Object, Object)
- Returns true if the leftOperand is less than the rightOperand.
getInstance
public static Comparer getInstance()
- Returns a IntegerComparer object.
lessThan
public final boolean lessThan(Object leftOperand,
Object rightOperand) throws ClassCastException
- Returns true if the leftOperand is less than the rightOperand.
- Throws: ClassCastException
- If operand objects are not Number objects.
ClassCastException is a RuntimeException, so compiler does not force you
to catch this exception.
- Overrides:
- lessThan in class Comparer
greaterThan
public final boolean greaterThan(Object leftOperand,
Object rightOperand) throws ClassCastException
- Returns true if the leftOperand is greater than the rightOperand.
- Throws: ClassCastException
- If operand objects are not Number objects.
ClassCastException is a RuntimeException, so compiler does not force you
to catch this exception.
- Overrides:
- greaterThan in class Comparer
equals

- Returns true if the leftOperand is equal to the rightOperand.
- Throws: ClassCastException
- If operand objects are not Number objects.
ClassCastException is a RuntimeException, so compiler does not force you
to catch this exception.
