Java - get long min value
2 points
Short solution:
xxxxxxxxxx1
long MIN_VALUE = Long.MIN_VALUE;2
3
System.out.println(MIN_VALUE); // -9223372036854775808Java Long min value is -9,223,372,036,854,775,808
Short solution to get long max value:
xxxxxxxxxx1
long MAX_VALUE = Long.MAX_VALUE;2
3
System.out.println(MAX_VALUE); // 9223372036854775807Java Long max value is 9,223,372,036,854,775,807
- Using build-in
Long.MIN_VALUE - Using Math power() method eg:
(long) Math.pow(2, 63) + 1 - Using bit shifting eg:
-1L << 63 - Using bit shifting and not eg:
~(~0L >>> 1)
