長類reverseBytes()方法 (Long class reverseBytes() method)

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

  reverseBytes()方法在java.lang包中可用。

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

  reverseBytes()方法用于返回通過反轉給定參數的二進制2的補碼表示形式的字節順序而生成的值。

• reverseBytes() 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.

  reverseBytes()方法是一個靜態方法，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，那么也不會出錯。

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

  reverseBytes()方法在反轉字節順序時不會引發異常。

Syntax:

句法：

    public static long reverseBytes (long value);

Parameter(s):

參數：

• long value – represents the long value to be parsed.

  long value –表示要解析的long值。

Return value:

返回值：

The return type of this method is long, it returns a long value generated by reversing the bytes order in 2's complement of the given long value.

此方法的返回類型為long ，它返回通過以給定long值的2的補碼反轉字節順序生成的long值。

Example:

例：

// Java program to demonstrate the example 
// of reverseBytes(long value) method of Long class
public class ReverseBytesOfLongClass {
public static void main(String[] args) {
long value = 1296;
// Display value
System.out.println("value: " + value);
// It returns the string representation of the given unsigned 
// long value denoted by the argument in binary by calling
// Long.toBinaryString(value)
System.out.println("Long.toBinaryString(value): " + Long.toBinaryString(value));
// It returns the value generated by reversing the order of the 
// bytes in the given argument value by calling //Long.reverseBytes(value)
System.out.println("Long.reverseBytes(value): " + Long.reverseBytes(value));
}
}

Output

輸出量

value: 1296
Long.toBinaryString(value): 10100010000
Long.reverseBytes(value): 1154328879490400256
