java reverse

整數類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()方法用于返回通過反轉給定參數的二進制2的補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()方法是一個靜態方法，它也可以使用類名進行訪問，如果我們嘗試使用類對象訪問該方法，那么我們也不會收到錯誤。

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

  reverse()方法在反轉位順序時不會引發異常。

Syntax:

句法：

    public static int reverse(int value);

Parameter(s):

參數：

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

  int value –表示要解析的整數值。

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 ，它返回一個整數值，該整數值是通過反轉給定整數值的2的補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 class
public class ReverseOfIntegerClass {
public static void main(String[] args) {
int value = 1296;
// Display value
System.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
