public static int compare(byte a, byte b)

Compares the two specified byte values, treating them as unsigned values between 0 and 255 inclusive. For example, (byte) -127 is considered greater than (byte) 127 because it is seen as having the value of positive 129.

Parameters

a:byte: the first byte to compare

lexicographicalComparator back to summary

lexicographicalComparator	back to summary
public static Comparator<byte[]> lexicographicalComparator() Returns a comparator that compares two `byte` arrays lexicographically. That is, it compares, using `compare(byte, byte)`), the first pair of values that follow any common prefix, or when one array is a prefix of the other, treats the shorter array as the lesser. For example, `[] < [0x01] < [0x01, 0x7F] < [0x01, 0x80] < [0x02]`. Values are treated as unsigned. The returned comparator is inconsistent with `Object#equals(Object)` (since arrays support only identity equality), but it is consistent with `java.util.Arrays#equals(byte[], byte[])`. Since 2.0

public static Comparator<byte[]> lexicographicalComparator()

Returns a comparator that compares two byte arrays lexicographically. That is, it compares, using compare(byte, byte)), the first pair of values that follow any common prefix, or when one array is a prefix of the other, treats the shorter array as the lesser. For example, [] < [0x01] < [0x01, 0x7F] < [0x01, 0x80] < [0x02]. Values are treated as unsigned.

The returned comparator is inconsistent with Object#equals(Object) (since arrays support only identity equality), but it is consistent with java.util.Arrays#equals(byte[], byte[]).

The implementor must ensure that `signum(compare(x, y)) == -signum(compare(y, x))` for all `x` and `y`. (This implies that `compare(x, y)` must throw an exception if and only if `compare(y, x)` throws an exception.) The implementor must also ensure that the relation is transitive: `((compare(x, y)>0) && (compare(y, z)>0))` implies `compare(x, z)>0`. Finally, the implementor must ensure that `compare(x, y)==0` implies that `signum(compare(x, z))==signum(compare(y, z))` for all `z`.

Doc from java.util.Comparator.compare.

Compares its two arguments for order. Returns a negative integer, zero, or a positive integer as the first argument is less than, equal to, or greater than the second.

The implementor must ensure that signum(compare(x, y)) == -signum(compare(y, x)) for all x and y. (This implies that compare(x, y) must throw an exception if and only if compare(y, x) throws an exception.)

The implementor must also ensure that the relation is transitive: ((compare(x, y)>0) && (compare(y, z)>0)) implies compare(x, z)>0.

Finally, the implementor must ensure that compare(x, y)==0 implies that signum(compare(x, z))==signum(compare(y, z)) for all z.

Parameters

left:byte[]: the first object to be compared.
