Below are some more details to explain this. Below programs illustrate the working of java.lang.Long.longValue() method. The MAX_VALUE property has a value of approximately 1.79E+308, or 2 1024.Values larger than MAX_VALUE are represented as Infinity.. Because MAX_VALUE is a static property of Number, you always use it as Number.MAX_VALUE, rather than as a property of a Number object you created. Maximum and Minimum Example in Java Our example program has two parts. Just Print the values using: Character.MAX_VALUE, Character.MIN_VALUE, Long.MAX_VALUE, Long.MIN_VALUE For Double and Long, these are huge. Java Program to convert Java Float to Numeric Primitive Data Types, Uninitialized primitive data types in C/C++ Program. Therefore, Java has constants to represent these numbers, so that these can be directly assigned to the variable without actually typing the whole number. The Long.max(long a, long b) java method returns the greater of two long values as if by calling Math.max. You can use Scanner class, added in Java 1.5 to read user input from the console. The officially supported range of values for Big integers is -(2 Integer.MAX_VALUE) -1 to +(2 Integer.MAX_VALUE) -1 . Recently in one interview , question was asked to find the the maximum or minimum value of the data type , there are many ways to do it , but the best solution is shared here ., most of the interviewee start using for loop or start remembering what is the exact range of the given data type . And, if you go over this number then you need something that can store bigger numbers then Long. max, min or average. public: long MaxValue = 9223372036854775807; public const long MaxValue = 9223372036854775807; val mutable MaxValue : int64 Public Const MaxValue As Long = 9223372036854775807 Field Value Int64 Remarks. A square number is a number in the form of n2. Long class defines three constants to designate long type's max value, min value and number of bits.
