Long.compare(): This method is available in java.lang.Long class of Java.
Syntax:
int java.lang.Long.compare(long x, long y)
This method takes two arguments of type long as its parameters. This method compares two long values numerically.
Parameters: Two parameters are required for this method.
x: the first long to compare.
y: the second long to compare.
Returns:
1. The value 0 if x == y.
2. A value less than 0 if x < y.
3. A value greater than 0 if x > y.
For Example:
long x = 10, y = 7
Long.compare(x,y) = > It returns 1.
Approach
Java
public class LongCompare {public static void main(String[] args) {long x = 10, y = 7;System.out.println(Long.compare(x, y));}}
Output:
1
Some methods of Long
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 two 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.
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 two complements binary forms (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.
