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.parseLong(CharSequence s, int beginIndex, int endIndex, int radix): It parses the CharSequence argument as a signed long in the specified radix, beginning at the beginIndex and extending to endIndex - 1.
Long.parseUnsignedLong(String s): It parses the string argument as an unsigned decimal long.
Long.parseUnsignedLong(String s, int radix): It parses the string argument as an unsigned long in the radix specified by the second argument.
Long.parseUnsignedLong(CharSequence s, int beginIndex, int endIndex, int radix): It parses the CharSequence argument as an unsigned long in the specified radix, beginning at the beginIndex and extending to endIndex - 1.
Long.remainderUnsigned(): It returns the unsigned remainder from dividing the first argument by the second where each argument and the result is interpreted as an unsigned value.
Long.reverse(): It returns the value obtained by reversing the order of the bits in the two's complement binary representation of the specified long value.
Long.reverseBytes(): It returns the value obtained by reversing the order of the bytes in the two's complement representation of the specified long value.
Long.rotateLeft(): It returns the value obtained by rotating the two's complement binary representation of the specified long value left by the specified number of bits.
Long.rotateRight(): It returns the value obtained by rotating the two's complement binary representation of the specified long value right by the specified number of bits.
Long.signum(): It returns the signum function of the specified long value.
Long.SIZE: The number of bits used to represent a long value in twos complements binary form (i.e 64).
Long.sum(): It adds two long values together as per the + operator.
Long.toBinaryString(): It returns a string representation of the long argument as an unsigned integer in base 2.
Long.toHexString(): It returns a string representation of the long argument as an unsigned integer in base 16.
Long.toOctalString(): It returns a string representation of the long argument as an unsigned integer in base 8.
Long.toString(long i): It returns a String object representing the specified long.
Long.toString(long i, int radix): It returns a string representation of the first argument in the radix specified by the second argument.
Long.toUnsignedString(): It returns a string representation of the argument as an unsigned decimal value.
Long.valueOf(long l): It returns a Long instance representing the specified long value.
Long.valueOf(String s): It returns a Long object holding the value of the specified String.
Long.valueOf(String s, int radix): It returns a Long object holding the value extracted from the specified String when parsed with the radix given by the second argument.
