java reverse

整數(shù)類reverse()方法 (Integer class reverse() method)

• reverse() method is available in java.lang package.

  reverse()方法在java.lang包中可用。

• reverse() method is used to returns the value generated by reversing the order of bits in binary 2's complement denotation of the given argument.

  reverse()方法用于返回通過(guò)反轉(zhuǎn)給定參數(shù)的二進(jìn)制2的補(bǔ)碼表示形式的位順序生成的值。

• reverse() method is a static method, it is accessible with the class name too and if we try to access the method with the class object then also we will not get an error.

  reverse()方法是一個(gè)靜態(tài)方法，它也可以使用類名進(jìn)行訪問(wèn)，如果我們嘗試使用類對(duì)象訪問(wèn)該方法，那么我們也不會(huì)收到錯(cuò)誤。

• reverse() method does not throw an exception at the time of reversing the order of bits.

  reverse()方法在反轉(zhuǎn)位順序時(shí)不會(huì)引發(fā)異常。

Syntax:

句法：

public static int reverse(int value);

Parameter(s):

參數(shù)：

• int value – represents the integer value to be parsed.

  int value –表示要解析的整數(shù)值。

Return value:

返回值：

The return type of this method is int, it returns an integer value generated by reversing the bits order in 2's complement of the given integer value.

此方法的返回類型為int ，它返回一個(gè)整數(shù)值，該整數(shù)值是通過(guò)反轉(zhuǎn)給定整數(shù)值的2的補(bǔ)碼中的位順序而生成的。

Example:

例：

// Java program to demonstrate the example // of reverse(int value) method of Integer classpublic class ReverseOfIntegerClass {public static void main(String[] args) {int value = 1296;// Display valueSystem.out.println("value:" + value);// It returns the string representation of the given unsigned // integer value denoted by the argument in binary by calling// Integer.toBinaryString(value)System.out.println("Integer.toBinaryString(value): " + Integer.toBinaryString(value));// It returns the value generated by reversing the // order of the bits in the given argument value // by calling Integer.reverse(value)System.out.println("Integer.reverse(value): " + Integer.reverse(value));} }

Output

輸出量

value:1296 Integer.toBinaryString(value): 10100010000 Integer.reverse(value): 144703488
