java integer min value

. ConclusionIn conjunction with the above analysis, the conclusion about value passing and reference passing can be drawn as follows:(1) The basic data type transmission value, the modification of the formal parameters will not affect the actual parameters;(2) Reference type is referenced, formal parameters and arguments point to the same memory address (the same object), so the modification of parameters w

class string, long, integer, etc., although the class but the use of value passing (tested) reference passing is the copy of the address, common objects, etc.http://464772913.iteye.com/blog/1483163 the concepts of "formal parameters" and "actual parameters" must be understood before Java value passing and reference pa

If the basic integer and floating-point precision does not meet the requirements, you can use two very flat useful classes in the Java.math package: BigInteger and BigDecimal. These two classes can handle numeric values that contain a sequence of arbitrary lengths.BigIntegerclass implements the arbitrary precision of theintegerOperationBigDecimalThe realization of arbitrary precisionfloating point numberThe operation uses a static ValueOf method to co

Because in many cases, if the data to be converted is NULL, the caller expects the default value to be returned.The default value that is automatically provided by the system does not meet our needs, such as the default value of int is 0, but in SQL queries, if the query fails, we expect a value less than 0, such as se

A set in Java is a collection that does not contain duplicate elements, specifically an element pair that does not contain e1.equals (E2). Allows NULL to be added in set. Set does not guarantee the order of elements in the collection. When an element is added to a set, if the specified element does not exist, the addition succeeds. That is, if the element E1 (E==null e1==null:e.queals (E1)) is not present in the set, E1 can be added to the set. The

In the process of some interview enterprises, many people value the basic assessment. Among them, the transfer of value and address is a fundamental ability to assess the key, here I summed up 5 kinds of typical examples, and finally made a summary First of all, there are 8 basic data types, with an int type as an example of a value. public static v
