Methods
Methods | Description |
---|---|
booleanValue() | Returns a Boolean primitive for the value of this Boolean object. |
compare() | Compares two Boolean values. |
compareTo() | Compares this Boolean instance with another. |
equals() | Returns a Boolean value true if the argument is a Boolean object that represents the same value as this object. |
getBoolean() | Returns a Boolean value true if the system property name is equal to the string “true”. |
hashCode() | Returns a hash code for the Boolean object. |
logicalAnd() | Returns the result of implementing logical AND operation on the assigned boolean operands. |
logicalOr() | Returns the result of implementing logical OR operation on the assigned boolean operands. |
logicalXor() | Returns the result of implementing logical XOR operation on the assigned boolean operands. |
parseBoolean() | Parses the string argument as a Boolean. |
toString() | Returns a String instance representing the specified Boolean’s value or the specified boolean. |
valueOf() | Returns a Boolean instance representing the specified Boolean value or string value. |
Example 1
Output:
Value of boolean object true is true. b1 is true. Logical And will return false
Example 2
Output:
Boolean value = true Hash Code for boolean value = 1231 String value = true Hash Code for String Value = 3569038 valueOf() method will return = true value of val is true
