| Method Detail |
public static int abs(int a)
int value.
If the argument is not negative, the argument is returned.
If the argument is negative, the negation of the argument is returned.
Note that if the argument is equal to the value of
Integer.MIN_VALUE, the most negative representable
int value, the result is that same value, which is
negative.
a - an int value.Integer.MIN_VALUEpublic static long abs(long a)
long value.
If the argument is not negative, the argument is returned.
If the argument is negative, the negation of the argument is returned.
Note that if the argument is equal to the value of
Long.MIN_VALUE, the most negative representable
long value, the result is that same value, which is
negative.
a - a long value.Long.MIN_VALUE
public static int max(int a,
int b)
int values. That is, the
result is the argument closer to the value of
Integer.MAX_VALUE. If the arguments have the same value,
the result is that same value.a - an int value.b - an int value.a and b.Long.MAX_VALUE
public static long max(long a,

long values. That is, the
result is the argument closer to the value of
Long.MAX_VALUE. If the arguments have the same value,
the result is that same value.a - a long value.b - a long value.a and b.Long.MAX_VALUE
public static int min(int a,
int b)
int values. That is, the
result the argument closer to the value of Integer.MIN_VALUE.
If the arguments have the same value, the result is that same value.a - an int value.b - an int value.a and b.Long.MIN_VALUE

long values. That is, the
result is the argument closer to the value of
Long.MIN_VALUE. If the arguments have the same value,
the result is that same value.a - a long value.b - a long value.a and b.Long.MIN_VALUE
