Java Long class
The Long class generally wraps the primitive type long into an object. An object of Long class contains a field with the type Long.
Methods:
This class is useful in providing various methods like a method which can be used to convert a double to a String and a method which can be used to convert a String into a double.
| Methods | Description |
|---|---|
| bitCount(long i) | It returns the number of one bits in two?s compliment binary representation. |
| byteValue() | It returns the value of Long as a byte after the conversion. |
| compare(long x, long y) | It compares the two long values. |
| compareTo(long another long) | It compares two long objects numerically. |
| compareUnsigned(long x, long y) | It compares the two long values keeping the values unsigned. |
| decode(String nm) | It is used to decode a string into Long. |
| divideUnsigned(long dividend, long divisor) | It returns the unsigned quotient for dividing the first argument by the second. |
| doubleValue() | It returns the value of Long as a double after the conversion. |
| equals(Object obj) | It compares the object with the specified object. |
| floatValue() | It returns the float type value for the given Long object. |
| getLong(String nm) | It determines the long value for the specified name. |
| getLong(String nm, Long val) | It returns the long value for the specified name. |
| hashCode() | It returns the hash code for the given Long object. |
| hashCode(Long value) | It returns the hash code for the given Long value. |
| highestOneBit(long i) | It returns a long value with at most one single bit in the highest order. |
| intValue() | It returns the value of Long as an int after the conversion. |
| longValue() | It returns the value of Long as a long after the conversion. |
| lowestOneBit(long i) | It returns a long value with at most one single bit in the lowest order. |
| max(long a, long b) | It returns the greater of the two long values. |
| min(long a, long b) | It returns the smaller of the two long values. |
| numberOfLeadingZeroes(long i) | It returns the total number of zero bytes in the highest order. |
| numberOfTrailingZeroes(long i) | It returns the total number of zero bytes in the lowest order. |
| parseLong(CharSequence s, int beginIndex, int endIndex, int radix) | It parses the CharSequence arguementwith a specified long in the given index |
| parseLong(String s) | It parses the string parameter as a signed decimal long. |
| parseLong(String s, int radix) | It parses the string argument as a signed long as given in the radix. |
| parseUnsignedLong(CharSequence s, int beginIndex, int ndIndex, int radix) | It parses the given CharSequence argument as an unsigned long in the given radix beginning from beginIndex and ending till endIndex-1. |
| parseUnsignedLong(String s) | It parses the given string argument as an unsigned long. |
| parseUnsignedLong(String s, int radix) | It parses the given string argument as an unsigned long in the index specified by the second argument. |
| remainderUnsigned(long dividend, long divisor) | It returns the unsigned remainder from dividing the first argument with the second argument. |
| reverse(long i) | It returns the value obtained by the reversing the given order of bits in 2?s complement binary representation. |
| reverseBytes(long i) | It returns the value obtained by the reversing the given order of bits in 2?s complement representation. |
| rotateLeft(long i, int distance) | It returns the value obtained by rotating the 2?s complement binary representation of the given long value by left and by the specified number of bits. |
| rotateRight(long i, int distance) | It returns the value obtained by rotating the 2?s complement binary representation of the given long value by right and by the specified number of bits. |
| shortValue() | It returns the short type value for the given Long object. |
| signum(long i) | It returns the signum function for the given long value. |
| sum(long a, long b) | It adds two long values as per the + operator. |
| toBinaryString(long i) | It returns the string representation for the given long argument as an unsigned argument with base 2. |
| toHexString(long i) | It returns the string representation for the given long argument as an unsigned argument with base 16. |
| toOctalString(long i) | It returns the string representation for the given long argument as an unsigned argument with base 8. |
| toString() | It returns the string which represents the long value. |
| toString(long i) | It returns the string which represents the specified long. |
| toString(long i, int radix) | It returns the string representation for the first argument which is specified by the second argument. |
| toUnsignedString(long i) | It returns the string representation for the argument as an unsigned decimal value. |
| toUnsignedString(long i, int radix) | It returns the string representation for the first argument as an unsigned integer value in the radix. |
| valueOf(l) | It returns a long instance which represents the specified value. |
| valueOf(String s) | It returns a long instance which holds the value of specified string. |
| valueOf(String s int radix) | It returns the Long object which holds the value of specified string when parsed with the radix provided by the second argument |
Example 1
Output:
67 is smaller than 98 The hashcode for the value '67' is given as :67 The short value for '98' is given as : 6
Example 2
Output:
The sum of '45' and '67' 'is given as :112 The reverse value for'12' is given as :3458764513820540928 The string representation for '67' is given as : 67
