There is an integer array that requests the minimum absolute value of the difference between the two. Remember, you only need to obtain the minimum value and do not need to find the two numbers.

I. Introduction
Before starting this chapter, I would like to raise a question: "If the absolute value of an integer is equal to itself, What is the number ?" If your answer is 0 and all positive numbers, please read this article with patience.
This chapter is the second part of my "code Mystery" series. The previous article "code mystery-opening/preface" briefly introduces the differences between computers

Implement the function double power (double base,int exponent) to find the exponent of base, do not use the library function, do not consider the problem of large numbers.
Note: It is not possible to determine whether two decimals are equal or not, because the computer indicates a decimal error, and we can only judge whether the absolute
Program apes are very lazy, you know!What we are sharing today is the integer wrapper class. In real-world development, we often need to operate an integer, or a variety of conversions and so on. I will give you a specific explanation of the use of the integer today. Look at the code:Package Com.herman.test;public class Integertest {public static void main (strin

above phenomenon, I used the JAVAP tool to disassemble the. class file generated by the Java compiler:By carefully reading the Java compiler's native bytecode, I found the following statement to assign a value to an integer variable:Integer v1=100;The Integer.valueof method is actually called.The following statement,

There are four kinds of integer types in Java, which are byte short int long, where byte is only one byte 0 or 1, which is not explained in detail here.
The other three types are as follows:
1,Basic type: Short bits number: 16Packing class: Java.lang.ShortMinimum value: short.min_value=-32768 (-2 of 15 of this side)Maximum
One of the previous articles mentions why Java generics use objects instead of primitive types. But the difference between the integer and int is still not understand, continue to Baidu a bit, found a big guy's article, Feel good, just reprint share.

Static String
toString (int i)Returns a String object that represents the specified integer.

toString (int i, int radix)Returns the string representation of the first argument, using the cardinality specified by the second argument.
mathematical operations, such as elementary prime numbers, logarithms, square roots, and trigonometric functions, all static methods.1. Common methods?//Abs method, the result is positiveDoubleD1 = Math.Abs (-5);//the value of D1 is 5DoubleD2 = Math.Abs (5);//The value of D2 is 5?//The Ceil method, which results in a double value of the smallest
the difference between int and integer1, integer is the wrapper class int, int is a basic data type of Java2. The integer variable must be instantiated before it can be used, and the int variable does not need3, the integer is actually a reference to the object, when new an integer, is actually generated a pointer to t
The difference between an int and an integer is, in large part, the difference between a basic data type and its wrapper class:
int is the basic type, the value is stored directly, and the integer is the object, and the object is pointed with a reference

The introduction of auto- boxing (autoboxing) and Auto-unpacking (unboxing)after JDK1.5, which made a lot of confusion for beginners in Java, was a part of me just now.First, there are some basic concepts that need to be understood:1. Ingeter is the wrapper class for int, and the initial value of int is null for 0,ingeter. 2. An integer is a class that declares
