byteValue

public byte byteValue()
Overrides:
byteValue in class Number

shortValue

public short shortValue()
Overrides:
shortValue in class Number

intValue

public int intValue()
Specified by:
intValue in class Number

longValue

public long longValue()
Specified by:
longValue in class Number

floatValue

public float floatValue()
Specified by:
floatValue in class Number

doubleValue

public double doubleValue()
Specified by:
doubleValue in class Number

toString

public String toString()
Overrides:
toString in class Object

hashCode

public int hashCode()
Overrides:
hashCode in class Object

equals

public boolean equals(Object)
Description copied from class: Object
Determines if this object is "equal" to another object.

In general, objects should be instances of the same class with the same guts to be considered equal. For example, the code below only prints same value since s and t are different strings though they have the same value: "hello".

 String s = new String("hello");
 String t = new String("hello");
 if (s.equals(t)) System.out.println("same value");
 if (s == t) System.out.println("same string");

 

Overrides:
equals in class Object
Following copied from class: java.lang.Object
Parameters:
is - the other Object to which this one is compared
Returns:
true if this Object is equal to other
