java.lang.Long
The Long class wraps a value of the primitive type long in an object. An object of type Long contains a single field whose type is long. In addition, this class provides several methods for converting a long to a String and a String to a long, as well as other constants and methods useful when dealing with a long.
Some Methods of Long Class.
Long.bitCount(): It returns the number of one-bits in the two's complement binary representation of the specified long value.
Long.BYTES: The number of bytes is used to represent a long value in twos complements binary form (i.e 8).
Long.compare(): It compares two long values numerically.
Long.compareUnsigned(): It compares two long values numerically treating the values as unsigned.
Long.decode(): It decodes a String into a Long. Accepts decimal, hexadecimal, and octal numbers.
Long.divideUnsigned(): It returns the unsigned quotient of dividing the first argument by the second where each argument and the result is interpreted as an unsigned value.
Long.getLong(String nm): It determines the long value of the system property with the specified name.
Long.getLong(String nm, long val): It determines the long value of the system property with the specified name.
Long.getLong(String nm, Long val): It returns the long value of the system property with the specified name. The first argument is treated as the name of a system property.
Long.hashCode(): It returns a hash code for a long value.
Long.highestOneBit(): It returns a long value with at most a single one-bit, in the position of the highest-order ("leftmost") one-bit in the specified long value.
Long.lowestOneBit(): It returns a long value with at most a single one-bit, in the position of the lowest-order ("rightmost") one-bit in the specified long value.
Long.max(): It returns the greater of two long values.
Long.MAX_VALUE: A constant holding the maximum value long can have, 2^63-1.
Long.min(): It returns the smaller of two long values.
Long.MIN_VALUE: A constant holding the minimum value long can have, -2^63.
Long.numberOfLeadingZeros(): It returns the number of zero bits preceding the highest-order("leftmost") one-bit in the two's complement binary representation of the specified long value.
Long.numberOfTrailingZeros(): It returns the number of zero bits following the lowest-order ("rightmost") one-bit in the two's complement binary representation of the specified long value.
Long.parseLong(String s): It parses the string argument as a signed decimal long.
Long.parseLong(String s, int radix): It parses the string argument as a signed long in the radix specified by the second argument.
